+# Firebase iOS Open Source Development [![Build Status](https://travis-ci.org/firebase/firebase-ios-sdk.svg?branch=master)](https://travis-ci.org/firebase/firebase-ios-sdk)
+
+This repository contains a subset of the Firebase iOS SDK source. It currently
+includes FirebaseCore, FirebaseAuth, FirebaseDatabase, FirebaseFirestore,
+FirebaseFunctions, FirebaseInstanceID, FirebaseInAppMessaging,
+FirebaseInAppMessagingDisplay, FirebaseMessaging and FirebaseStorage.
+
+The repository also includes GoogleUtilities source. The
+[GoogleUtilities](GoogleUtilities/README.md) pod is
+a set of utilities used by Firebase and other Google products.
+
+Firebase is an app development platform with tools to help you build, grow and
+monetize your app. More information about Firebase can be found at
+[https://firebase.google.com](https://firebase.google.com).
+
+## Installation
+
+See the three subsections for details about three different installation methods.
+1. [Standard pod install](README.md#standard-pod-install)
+1. [Installing from the GitHub repo](README.md#installing-from-github)
+1. [Experimental Carthage](README.md#carthage-ios-only)
+
+### Standard pod install
+
+Go to
+[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
+
+### Installing from GitHub
+
+For releases starting with 5.0.0, the source for each release is also deployed
+to CocoaPods master and available via standard
+[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
+
+These instructions can be used to access the Firebase repo at other branches,
+tags, or commits.
+
+#### Background
+
+See
+[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
+for instructions and options about overriding pod source locations.
+
+#### Accessing Firebase Source Snapshots
+
+All of the official releases are tagged in this repo and available via CocoaPods. To access a local
+source snapshot or unreleased branch, use Podfile directives like the following:
+
+To access FirebaseFirestore via a branch:
+```
+pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+```
+
+To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
+
+```
+pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
+pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
+```
+
+### Carthage (iOS only)
+
+Instructions for the experimental Carthage distribution are at
+[Carthage](Carthage.md).
+
+### Rome
+
+Instructions for installing binary frameworks via
+[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
+
+## Development
+
+To develop Firebase software in this repository, ensure that you have at least
+the following software:
+
+  * Xcode 10.1 (or later)
+  * CocoaPods 1.7.2 (or later)
+
+For the pod that you want to develop:
+
+`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open`
+
+Firestore and Functions have self contained Xcode projects. See
+[Firestore/README.md](Firestore/README.md) and
+[Functions/README.md](Functions/README.md).
+
+### Adding a New Firebase Pod
+
+See [AddNewPod.md](AddNewPod.md).
+
+### Code Formatting
+
+To ensure that the code is formatted consistently, run the script
+[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
+before creating a PR.
+
+Travis will verify that any code changes are done in a style compliant way. Install
+`clang-format` and `swiftformat`.
+These commands will get the right versions:
+
+```
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/773cb75d360b58f32048f5964038d09825a507c8/Formula/clang-format.rb
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/3dfea1004e0736754bbf49673cca8aaed8a94089/Formula/swiftformat.rb
+```
+
+Note: if you already have a newer version of these installed you may need to
+`brew switch` to this version.
+
+### Running Unit Tests
+
+Select a scheme and press Command-u to build a component and run its unit tests.
+
+#### Viewing Code Coverage
+
+First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
+
+After running the `AllUnitTests_iOS` scheme in Xcode, execute
+`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
+at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
+
+### Running Sample Apps
+In order to run the sample apps and integration tests, you'll need valid
+`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
+files without real values, but can be replaced with real plist files. To get your own
+`GoogleService-Info.plist` files:
+
+1. Go to the [Firebase Console](https://console.firebase.google.com/)
+2. Create a new Firebase project, if you don't already have one
+3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
+identifier (e.g. `com.google.Database-Example`)
+4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
+(e.g. in [Example/Database/App/](Example/Database/App/));
+
+Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
+special Apple capabilities, and you will have to change the sample app to use a unique bundle
+identifier that you can control in your own Apple Developer account.
+
+## Specific Component Instructions
+See the sections below for any special instructions for those components.
+
+### Firebase Auth
+
+If you're doing specific Firebase Auth development, see
+[the Auth Sample README](Example/Auth/README.md) for instructions about
+building and running the FirebaseAuth pod along with various samples and tests.
+
+### Firebase Database
+
+To run the Database Integration tests, make your database authentication rules
+[public](https://firebase.google.com/docs/database/security/quickstart).
+
+### Firebase Storage
+
+To run the Storage Integration tests, follow the instructions in
+[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
+
+#### Push Notifications
+
+Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
+In order to actually test receiving push notifications, you will need to:
+
+1. Change the bundle identifier of the sample app to something you own in your Apple Developer
+account, and enable that App ID for push notifications.
+2. You'll also need to
+[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
+at **Project Settings > Cloud Messaging > [Your Firebase App]**.
+3. Ensure your iOS device is added to your Apple Developer portal as a test device.
+
+#### iOS Simulator
+
+The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
+In order to receive push notifications, you'll have to follow the steps above and run the app on a
+physical device.
+
+## Community Supported Efforts
+
+We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
+very grateful!  We'd like to empower as many developers as we can to be able to use Firebase and
+participate in the Firebase community.
+
+### macOS and tvOS
+Thanks to contributions from the community, FirebaseAuth, FirebaseCore, FirebaseDatabase, FirebaseMessaging,
+FirebaseFirestore, FirebaseFunctions and FirebaseStorage now compile, run unit tests, and work on
+macOS and tvOS.
+
+For tvOS, checkout the [Sample](Example/tvOSSample).
+
+Keep in mind that macOS and tvOS are not officially supported by Firebase, and this repository is
+actively developed primarily for iOS. While we can catch basic unit test issues with Travis, there
+may be some changes where the SDK no longer works as expected on macOS or tvOS. If you encounter
+this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
+
+Note that the Firebase pod is not available for macOS and tvOS.
+
+To install, add a subset of the following to the Podfile:
+
+```
+pod 'FirebaseAuth'
+pod 'FirebaseCore'
+pod 'FirebaseDatabase'
+pod 'FirebaseFirestore'
+pod 'FirebaseFunctions'
+pod 'FirebaseMessaging'
+pod 'FirebaseStorage'
+```
+

+# Firebase iOS Open Source Development [![Build Status](https://travis-ci.org/firebase/firebase-ios-sdk.svg?branch=master)](https://travis-ci.org/firebase/firebase-ios-sdk)
+
+This repository contains a subset of the Firebase iOS SDK source. It currently
+includes FirebaseCore, FirebaseAuth, FirebaseDatabase, FirebaseFirestore,
+FirebaseFunctions, FirebaseInstanceID, FirebaseInAppMessaging,
+FirebaseInAppMessagingDisplay, FirebaseMessaging and FirebaseStorage.
+
+The repository also includes GoogleUtilities source. The
+[GoogleUtilities](GoogleUtilities/README.md) pod is
+a set of utilities used by Firebase and other Google products.
+
+Firebase is an app development platform with tools to help you build, grow and
+monetize your app. More information about Firebase can be found at
+[https://firebase.google.com](https://firebase.google.com).
+
+## Installation
+
+See the three subsections for details about three different installation methods.
+1. [Standard pod install](README.md#standard-pod-install)
+1. [Installing from the GitHub repo](README.md#installing-from-github)
+1. [Experimental Carthage](README.md#carthage-ios-only)
+
+### Standard pod install
+
+Go to
+[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
+
+### Installing from GitHub
+
+For releases starting with 5.0.0, the source for each release is also deployed
+to CocoaPods master and available via standard
+[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
+
+These instructions can be used to access the Firebase repo at other branches,
+tags, or commits.
+
+#### Background
+
+See
+[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
+for instructions and options about overriding pod source locations.
+
+#### Accessing Firebase Source Snapshots
+
+All of the official releases are tagged in this repo and available via CocoaPods. To access a local
+source snapshot or unreleased branch, use Podfile directives like the following:
+
+To access FirebaseFirestore via a branch:
+```
+pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+```
+
+To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
+
+```
+pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
+pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
+```
+
+### Carthage (iOS only)
+
+Instructions for the experimental Carthage distribution are at
+[Carthage](Carthage.md).
+
+### Rome
+
+Instructions for installing binary frameworks via
+[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
+
+## Development
+
+To develop Firebase software in this repository, ensure that you have at least
+the following software:
+
+  * Xcode 10.1 (or later)
+  * CocoaPods 1.7.2 (or later)
+
+For the pod that you want to develop:
+
+`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open`
+
+Firestore and Functions have self contained Xcode projects. See
+[Firestore/README.md](Firestore/README.md) and
+[Functions/README.md](Functions/README.md).
+
+### Adding a New Firebase Pod
+
+See [AddNewPod.md](AddNewPod.md).
+
+### Code Formatting
+
+To ensure that the code is formatted consistently, run the script
+[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
+before creating a PR.
+
+Travis will verify that any code changes are done in a style compliant way. Install
+`clang-format` and `swiftformat`.
+These commands will get the right versions:
+
+```
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/773cb75d360b58f32048f5964038d09825a507c8/Formula/clang-format.rb
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/3dfea1004e0736754bbf49673cca8aaed8a94089/Formula/swiftformat.rb
+```
+
+Note: if you already have a newer version of these installed you may need to
+`brew switch` to this version.
+
+### Running Unit Tests
+
+Select a scheme and press Command-u to build a component and run its unit tests.
+
+#### Viewing Code Coverage
+
+First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
+
+After running the `AllUnitTests_iOS` scheme in Xcode, execute
+`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
+at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
+
+### Running Sample Apps
+In order to run the sample apps and integration tests, you'll need valid
+`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
+files without real values, but can be replaced with real plist files. To get your own
+`GoogleService-Info.plist` files:
+
+1. Go to the [Firebase Console](https://console.firebase.google.com/)
+2. Create a new Firebase project, if you don't already have one
+3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
+identifier (e.g. `com.google.Database-Example`)
+4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
+(e.g. in [Example/Database/App/](Example/Database/App/));
+
+Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
+special Apple capabilities, and you will have to change the sample app to use a unique bundle
+identifier that you can control in your own Apple Developer account.
+
+## Specific Component Instructions
+See the sections below for any special instructions for those components.
+
+### Firebase Auth
+
+If you're doing specific Firebase Auth development, see
+[the Auth Sample README](Example/Auth/README.md) for instructions about
+building and running the FirebaseAuth pod along with various samples and tests.
+
+### Firebase Database
+
+To run the Database Integration tests, make your database authentication rules
+[public](https://firebase.google.com/docs/database/security/quickstart).
+
+### Firebase Storage
+
+To run the Storage Integration tests, follow the instructions in
+[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
+
+#### Push Notifications
+
+Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
+In order to actually test receiving push notifications, you will need to:
+
+1. Change the bundle identifier of the sample app to something you own in your Apple Developer
+account, and enable that App ID for push notifications.
+2. You'll also need to
+[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
+at **Project Settings > Cloud Messaging > [Your Firebase App]**.
+3. Ensure your iOS device is added to your Apple Developer portal as a test device.
+
+#### iOS Simulator
+
+The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
+In order to receive push notifications, you'll have to follow the steps above and run the app on a
+physical device.
+
+## Community Supported Efforts
+
+We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
+very grateful!  We'd like to empower as many developers as we can to be able to use Firebase and
+participate in the Firebase community.
+
+### macOS and tvOS
+Thanks to contributions from the community, FirebaseAuth, FirebaseCore, FirebaseDatabase, FirebaseMessaging,
+FirebaseFirestore, FirebaseFunctions and FirebaseStorage now compile, run unit tests, and work on
+macOS and tvOS.
+
+For tvOS, checkout the [Sample](Example/tvOSSample).
+
+Keep in mind that macOS and tvOS are not officially supported by Firebase, and this repository is
+actively developed primarily for iOS. While we can catch basic unit test issues with Travis, there
+may be some changes where the SDK no longer works as expected on macOS or tvOS. If you encounter
+this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
+
+Note that the Firebase pod is not available for macOS and tvOS.
+
+To install, add a subset of the following to the Podfile:
+
+```
+pod 'FirebaseAuth'
+pod 'FirebaseCore'
+pod 'FirebaseDatabase'
+pod 'FirebaseFirestore'
+pod 'FirebaseFunctions'
+pod 'FirebaseMessaging'
+pod 'FirebaseStorage'
+```

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Firebase iOS Open Source Development [![Build Status](https://travis-ci.org/firebase/firebase-ios-sdk.svg?branch=master)](https://travis-ci.org/firebase/firebase-ios-sdk)
+
+This repository contains a subset of the Firebase iOS SDK source. It currently
+includes FirebaseCore, FirebaseABTesting, FirebaseAuth, FirebaseDatabase,
+FirebaseFirestore, FirebaseFunctions, FirebaseInstanceID, FirebaseInAppMessaging,
+FirebaseInAppMessagingDisplay, FirebaseMessaging and FirebaseStorage.
+
+The repository also includes GoogleUtilities source. The
+[GoogleUtilities](GoogleUtilities/README.md) pod is
+a set of utilities used by Firebase and other Google products.
+
+Firebase is an app development platform with tools to help you build, grow and
+monetize your app. More information about Firebase can be found at
+[https://firebase.google.com](https://firebase.google.com).
+
+## Installation
+
+See the three subsections for details about three different installation methods.
+1. [Standard pod install](README.md#standard-pod-install)
+1. [Installing from the GitHub repo](README.md#installing-from-github)
+1. [Experimental Carthage](README.md#carthage-ios-only)
+
+### Standard pod install
+
+Go to
+[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
+
+### Installing from GitHub
+
+For releases starting with 5.0.0, the source for each release is also deployed
+to CocoaPods master and available via standard
+[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
+
+These instructions can be used to access the Firebase repo at other branches,
+tags, or commits.
+
+#### Background
+
+See
+[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
+for instructions and options about overriding pod source locations.
+
+#### Accessing Firebase Source Snapshots
+
+All of the official releases are tagged in this repo and available via CocoaPods. To access a local
+source snapshot or unreleased branch, use Podfile directives like the following:
+
+To access FirebaseFirestore via a branch:
+```
+pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+```
+
+To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
+
+```
+pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
+pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
+```
+
+### Carthage (iOS only)
+
+Instructions for the experimental Carthage distribution are at
+[Carthage](Carthage.md).
+
+### Rome
+
+Instructions for installing binary frameworks via
+[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
+
+## Development
+
+To develop Firebase software in this repository, ensure that you have at least
+the following software:
+
+  * Xcode 10.1 (or later)
+  * CocoaPods 1.7.2 (or later)
+
+For the pod that you want to develop:
+
+`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open`
+
+Firestore has a self contained Xcode project. See
+[Firestore/README.md](Firestore/README.md).
+
+### Adding a New Firebase Pod
+
+See [AddNewPod.md](AddNewPod.md).
+
+### Code Formatting
+
+To ensure that the code is formatted consistently, run the script
+[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
+before creating a PR.
+
+Travis will verify that any code changes are done in a style compliant way. Install
+`clang-format` and `swiftformat`.
+These commands will get the right versions:
+
+```
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/773cb75d360b58f32048f5964038d09825a507c8/Formula/clang-format.rb
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/3dfea1004e0736754bbf49673cca8aaed8a94089/Formula/swiftformat.rb
+```
+
+Note: if you already have a newer version of these installed you may need to
+`brew switch` to this version.
+
+### Running Unit Tests
+
+Select a scheme and press Command-u to build a component and run its unit tests.
+
+#### Viewing Code Coverage
+
+First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
+
+After running the `AllUnitTests_iOS` scheme in Xcode, execute
+`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
+at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
+
+### Running Sample Apps
+In order to run the sample apps and integration tests, you'll need valid
+`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
+files without real values, but can be replaced with real plist files. To get your own
+`GoogleService-Info.plist` files:
+
+1. Go to the [Firebase Console](https://console.firebase.google.com/)
+2. Create a new Firebase project, if you don't already have one
+3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
+identifier (e.g. `com.google.Database-Example`)
+4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
+(e.g. in [Example/Database/App/](Example/Database/App/));
+
+Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
+special Apple capabilities, and you will have to change the sample app to use a unique bundle
+identifier that you can control in your own Apple Developer account.
+
+## Specific Component Instructions
+See the sections below for any special instructions for those components.
+
+### Firebase Auth
+
+If you're doing specific Firebase Auth development, see
+[the Auth Sample README](Example/Auth/README.md) for instructions about
+building and running the FirebaseAuth pod along with various samples and tests.
+
+### Firebase Database
+
+To run the Database Integration tests, make your database authentication rules
+[public](https://firebase.google.com/docs/database/security/quickstart).
+
+### Firebase Storage
+
+To run the Storage Integration tests, follow the instructions in
+[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
+
+#### Push Notifications
+
+Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
+In order to actually test receiving push notifications, you will need to:
+
+1. Change the bundle identifier of the sample app to something you own in your Apple Developer
+account, and enable that App ID for push notifications.
+2. You'll also need to
+[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
+at **Project Settings > Cloud Messaging > [Your Firebase App]**.
+3. Ensure your iOS device is added to your Apple Developer portal as a test device.
+
+#### iOS Simulator
+
+The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
+In order to receive push notifications, you'll have to follow the steps above and run the app on a
+physical device.
+
+## Community Supported Efforts
+
+We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
+very grateful!  We'd like to empower as many developers as we can to be able to use Firebase and
+participate in the Firebase community.
+
+### macOS and tvOS
+Thanks to contributions from the community, FirebaseABTesting, FirebaseAuth, FirebaseCore,
+FirebaseDatabase, FirebaseMessaging,
+FirebaseFirestore, FirebaseFunctions and FirebaseStorage now compile, run unit tests, and work on
+macOS and tvOS.
+
+For tvOS, checkout the [Sample](Example/tvOSSample).
+
+Keep in mind that macOS and tvOS are not officially supported by Firebase, and this repository is
+actively developed primarily for iOS. While we can catch basic unit test issues with Travis, there
+may be some changes where the SDK no longer works as expected on macOS or tvOS. If you encounter
+this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
+
+Note that the Firebase pod is not available for macOS and tvOS.
+
+To install, add a subset of the following to the Podfile:
+
+```
+pod 'FirebaseABTesting'
+pod 'FirebaseAuth'
+pod 'FirebaseCore'
+pod 'FirebaseDatabase'
+pod 'FirebaseFirestore'
+pod 'FirebaseFunctions'
+pod 'FirebaseMessaging'
+pod 'FirebaseStorage'
+```
+
+## Roadmap
+
+See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source
+plans and directions.
+
+## Contributing
+
+See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase
+iOS SDK.

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+# Firebase iOS Open Source Development [![Build Status](https://travis-ci.org/firebase/firebase-ios-sdk.svg?branch=master)](https://travis-ci.org/firebase/firebase-ios-sdk)
+
+This repository contains a subset of the Firebase iOS SDK source. It currently
+includes FirebaseCore, FirebaseABTesting, FirebaseAuth, FirebaseDatabase,
+FirebaseFirestore, FirebaseFunctions, FirebaseInstanceID, FirebaseInAppMessaging,
+FirebaseInAppMessagingDisplay, FirebaseMessaging and FirebaseStorage.
+
+The repository also includes GoogleUtilities source. The
+[GoogleUtilities](GoogleUtilities/README.md) pod is
+a set of utilities used by Firebase and other Google products.
+
+Firebase is an app development platform with tools to help you build, grow and
+monetize your app. More information about Firebase can be found at
+[https://firebase.google.com](https://firebase.google.com).
+
+## Installation
+
+See the three subsections for details about three different installation methods.
+1. [Standard pod install](README.md#standard-pod-install)
+1. [Installing from the GitHub repo](README.md#installing-from-github)
+1. [Experimental Carthage](README.md#carthage-ios-only)
+
+### Standard pod install
+
+Go to
+[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
+
+### Installing from GitHub
+
+For releases starting with 5.0.0, the source for each release is also deployed
+to CocoaPods master and available via standard
+[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
+
+These instructions can be used to access the Firebase repo at other branches,
+tags, or commits.
+
+#### Background
+
+See
+[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
+for instructions and options about overriding pod source locations.
+
+#### Accessing Firebase Source Snapshots
+
+All of the official releases are tagged in this repo and available via CocoaPods. To access a local
+source snapshot or unreleased branch, use Podfile directives like the following:
+
+To access FirebaseFirestore via a branch:
+```
+pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+```
+
+To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
+
+```
+pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
+pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
+```
+
+### Carthage (iOS only)
+
+Instructions for the experimental Carthage distribution are at
+[Carthage](Carthage.md).
+
+### Rome
+
+Instructions for installing binary frameworks via
+[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
+
+## Development
+
+To develop Firebase software in this repository, ensure that you have at least
+the following software:
+
+  * Xcode 10.1 (or later)
+  * CocoaPods 1.7.2 (or later)
+
+For the pod that you want to develop:
+
+`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open`
+
+Firestore has a self contained Xcode project. See
+[Firestore/README.md](Firestore/README.md).
+
+### Adding a New Firebase Pod
+
+See [AddNewPod.md](AddNewPod.md).
+
+### Code Formatting
+
+To ensure that the code is formatted consistently, run the script
+[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
+before creating a PR.
+
+Travis will verify that any code changes are done in a style compliant way. Install
+`clang-format` and `swiftformat`.
+These commands will get the right versions:
+
+```
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/773cb75d360b58f32048f5964038d09825a507c8/Formula/clang-format.rb
+brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/3dfea1004e0736754bbf49673cca8aaed8a94089/Formula/swiftformat.rb
+```
+
+Note: if you already have a newer version of these installed you may need to
+`brew switch` to this version.
+
+### Running Unit Tests
+
+Select a scheme and press Command-u to build a component and run its unit tests.
+
+#### Viewing Code Coverage
+
+First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
+
+After running the `AllUnitTests_iOS` scheme in Xcode, execute
+`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
+at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
+
+### Running Sample Apps
+In order to run the sample apps and integration tests, you'll need valid
+`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
+files without real values, but can be replaced with real plist files. To get your own
+`GoogleService-Info.plist` files:
+
+1. Go to the [Firebase Console](https://console.firebase.google.com/)
+2. Create a new Firebase project, if you don't already have one
+3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
+identifier (e.g. `com.google.Database-Example`)
+4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
+(e.g. in [Example/Database/App/](Example/Database/App/));
+
+Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
+special Apple capabilities, and you will have to change the sample app to use a unique bundle
+identifier that you can control in your own Apple Developer account.
+
+## Specific Component Instructions
+See the sections below for any special instructions for those components.
+
+### Firebase Auth
+
+If you're doing specific Firebase Auth development, see
+[the Auth Sample README](Example/Auth/README.md) for instructions about
+building and running the FirebaseAuth pod along with various samples and tests.
+
+### Firebase Database
+
+To run the Database Integration tests, make your database authentication rules
+[public](https://firebase.google.com/docs/database/security/quickstart).
+
+### Firebase Storage
+
+To run the Storage Integration tests, follow the instructions in
+[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
+
+#### Push Notifications
+
+Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
+In order to actually test receiving push notifications, you will need to:
+
+1. Change the bundle identifier of the sample app to something you own in your Apple Developer
+account, and enable that App ID for push notifications.
+2. You'll also need to
+[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
+at **Project Settings > Cloud Messaging > [Your Firebase App]**.
+3. Ensure your iOS device is added to your Apple Developer portal as a test device.
+
+#### iOS Simulator
+
+The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
+In order to receive push notifications, you'll have to follow the steps above and run the app on a
+physical device.
+
+## Community Supported Efforts
+
+We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
+very grateful!  We'd like to empower as many developers as we can to be able to use Firebase and
+participate in the Firebase community.
+
+### macOS and tvOS
+Thanks to contributions from the community, FirebaseABTesting, FirebaseAuth, FirebaseCore,
+FirebaseDatabase, FirebaseMessaging,
+FirebaseFirestore, FirebaseFunctions and FirebaseStorage now compile, run unit tests, and work on
+macOS and tvOS.
+
+For tvOS, checkout the [Sample](Example/tvOSSample).
+
+Keep in mind that macOS and tvOS are not officially supported by Firebase, and this repository is
+actively developed primarily for iOS. While we can catch basic unit test issues with Travis, there
+may be some changes where the SDK no longer works as expected on macOS or tvOS. If you encounter
+this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
+
+Note that the Firebase pod is not available for macOS and tvOS.
+
+To install, add a subset of the following to the Podfile:
+
+```
+pod 'FirebaseABTesting'
+pod 'FirebaseAuth'
+pod 'FirebaseCore'
+pod 'FirebaseDatabase'
+pod 'FirebaseFirestore'
+pod 'FirebaseFunctions'
+pod 'FirebaseMessaging'
+pod 'FirebaseStorage'
+```
