# Firebase iOS Open Source Development [](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, FirebaseRemoteConfig, 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)
|
|
* [CocoaPods generate](https://github.com/square/cocoapods-generate)
|
|
|
|
For the pod that you want to develop:
|
|
|
|
`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
|
|
|
|
Note: If the CocoaPods cache is out of date, you may need to run
|
|
`pod repo update` before the `pod gen` command.
|
|
|
|
Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
|
|
those platforms. Since 10.2, Xcode does not properly handle multi-platform
|
|
CocoaPods workspaces.
|
|
|
|
Firestore has a self contained Xcode project. See
|
|
[Firestore/README.md](Firestore/README.md).
|
|
|
|
### Development for Catalyst
|
|
* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
|
|
* Check the Mac box in the App-iOS Build Settings
|
|
* Sign the App in the Settings Signing & Capabilities tab
|
|
* Click Pods in the Project Manager
|
|
* Add Signing to the iOS host app and unit test targets
|
|
* Select the Unit-unit scheme
|
|
* Run it to build and test
|
|
|
|
### 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 upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/e3496d9/Formula/clang-format.rb
|
|
brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/7963c3d/Formula/swiftformat.rb
|
|
```
|
|
|
|
Note: if you already have a newer version of these installed you may need to
|
|
`brew switch` to this version.
|
|
|
|
To update this section, find the versions of clang-format and swiftformat.rb to
|
|
match the versions in the CI failure logs
|
|
[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
|
|
|
|
### 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.
|
|
|
|
### tvOS, macOS, and Catalyst
|
|
Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
|
|
tvOS, macOS, and Catalyst.
|
|
|
|
For tvOS, checkout the [Sample](Example/tvOSSample).
|
|
|
|
Keep in mind that macOS, Catalyst 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).
|
|
|
|
During app setup in the console, you may get to a step that mentions something like "Checking if the app
|
|
has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/Catalyst.
|
|
**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
|
|
|
|
To install, add a subset of the following to the Podfile:
|
|
|
|
```
|
|
pod 'Firebase/ABTesting'
|
|
pod 'Firebase/Auth'
|
|
pod 'Firebase/Crashlytics'
|
|
pod 'Firebase/Database'
|
|
pod 'Firebase/Firestore'
|
|
pod 'Firebase/Functions'
|
|
pod 'Firebase/Messaging'
|
|
pod 'Firebase/RemoteConfig'
|
|
pod 'Firebase/Storage'
|
|
```
|
|
|
|
#### Additional Catalyst Notes
|
|
|
|
* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
|
|
to Build Settings.
|
|
* FirebaseFirestore requires signing the
|
|
[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).
