-# 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, 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, FirebaseABTesting, FirebaseAuth, FirebaseCore,
-FirebaseDatabase, FirebaseMessaging, FirebaseFirestore,
-FirebaseFunctions, FirebaseRemoteConfig, and FirebaseStorage 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).
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting'
-pod 'Firebase/Auth'
-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).

 /**
- * Converts anything to anything, with an emphasis on performance and
- * safety.
  *
- * @author Andrei Alexandrescu (andrei.alexandrescu@fb.com)
+ * This file provides a generic interface for converting objects to and from
+ * string-like types (std::string, fbstring, StringPiece), as well as
+ * range-checked conversions between numeric and enum types. The mechanisms are
+ * extensible, so that user-specified types can add folly::to support.
+ *
+ *******************************************************************************
+ * TYPE -> STRING CONVERSIONS
+ *******************************************************************************
+ * You can call the to<std::string> or to<fbstring>. These are variadic
+ * functions that convert their arguments to strings, and concatenate them to
+ * form a result. So, for example,
+ *
+ * auto str = to<std::string>(123, "456", 789);
+ *
+ * Sets str to "123456789".
+ *
+ * In addition to just concatenating the arguments, related functions can
+ * delimit them with some string: toDelim<std::string>(",", "123", 456, "789")
+ * will return the string "123,456,789".
+ *
+ * toAppend does not return a string; instead, it takes a pointer to a string as
+ * its last argument, and appends the result of the concatenation into it:
+ * std::string str = "123";
+ * toAppend(456, "789", &str); // Now str is "123456789".
+ *
+ * The toAppendFit function acts like toAppend, but it precalculates the size
+ * required to perform the append operation, and reserves that space in the
+ * output string before actually inserting its arguments. This can sometimes
+ * save on string expansion, but beware: appending to the same string many times
+ * with toAppendFit is likely a pessimization, since it will resize the string
+ * once per append.
+ *
+ * The combination of the append and delim variants also exist: toAppendDelim
+ * and toAppendDelimFit are defined, with the obvious semantics.
+ *
+ *******************************************************************************
+ * STRING -> TYPE CONVERSIONS
+ *******************************************************************************
+ * Going in the other direction, and parsing a string into a C++ type, is also
+ * supported:
+ * to<int>("123"); // Returns 123.
+ *
+ * Out of range (e.g. to<std::uint8_t>("1000")), or invalidly formatted (e.g.
+ * to<int>("four")) inputs will throw. If throw-on-error is undesirable (for
+ * instance: you're dealing with untrusted input, and want to protect yourself
+ * from users sending you down a very slow exception-throwing path), you can use
+ * tryTo<T>, which will return an Expected<T, ConversionCode>.
+ *
+ * There are overloads of to() and tryTo() that take a StringPiece*. These parse
+ * out a type from the beginning of a string, and modify the passed-in
+ * StringPiece to indicate the portion of the string not consumed.
+ *
+ *******************************************************************************
+ * NUMERIC / ENUM CONVERSIONS
+ *******************************************************************************
+ * Conv also supports a to<T>(S) overload, where T and S are numeric or enum
+ * types, that checks to see that the target type can represent its argument,
+ * and will throw if it cannot. This includes cases where a floating point ->
+ * integral conversion is attempted on a value with a non-zero fractional
+ * component, and integral -> floating point conversions that would lose
+ * precision. Enum conversions are range-checked for the underlying type of the
+ * enum, but there is no check that the input value is a valid choice of enum
+ * value.
+ *
+ *******************************************************************************
+ * CUSTOM TYPE CONVERSIONS
+ *******************************************************************************
+ * Users may customize the string conversion functionality for their own data
+ * types, . The key functions you should implement are:
+ * // Two functions to allow conversion to your type from a string.
+ * Expected<StringPiece, ConversionCode> parseTo(folly::StringPiece in,
+ *     YourType& out);
+ * YourErrorType makeConversionError(YourErrorType in, StringPiece in);
+ * // Two functions to allow conversion from your type to a string.
+ * template <class String>
+ * void toAppend(const YourType& in, String* out);
+ * size_t estimateSpaceNeeded(const YourType& in);
+ *
+ * These are documented below, inline.
