# Firebase Apple Open Source Development
|
|
|
|
This repository contains the source code for all Apple platform Firebase SDKs except FirebaseAnalytics.
|
|
|
|
Firebase is an app development platform with tools to help you build, grow, and
|
|
monetize your app. More information about Firebase can be found on the
|
|
[official Firebase website](https://firebase.google.com).
|
|
|
|
## Installation
|
|
|
|
See the subsections below for details about the different installation methods. Where
|
|
available, it's recommended to install any libraries with a `Swift` suffix to get the
|
|
best experience when writing your app in Swift.
|
|
|
|
1. [Standard pod install](#standard-pod-install)
|
|
2. [Swift Package Manager](#swift-package-manager)
|
|
3. [Installing from the GitHub repo](#installing-from-github)
|
|
4. [Experimental Carthage](#carthage-ios-only)
|
|
|
|
### Standard pod install
|
|
|
|
For instructions on the standard pod install, visit:
|
|
[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
|
|
|
|
### Swift Package Manager
|
|
|
|
Instructions for [Swift Package Manager](https://swift.org/package-manager/) support can be
|
|
found in the [SwiftPackageManager.md](SwiftPackageManager.md) Markdown file.
|
|
|
|
### Installing from GitHub
|
|
|
|
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 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:
|
|
```ruby
|
|
pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'main'
|
|
pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'main'
|
|
```
|
|
|
|
To access FirebaseMessaging via a checked-out version of the firebase-ios-sdk repo:
|
|
```ruby
|
|
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 can be found at
|
|
[Carthage.md](Carthage.md).
|
|
|
|
### Using Firebase from a Framework or a library
|
|
|
|
For details on using Firebase from a Framework or a library, refer to [firebase_in_libraries.md](docs/firebase_in_libraries.md).
|
|
|
|
## Development
|
|
|
|
To develop Firebase software in this repository, ensure that you have at least
|
|
the following software:
|
|
|
|
* Xcode 15.2 (or later)
|
|
|
|
CocoaPods is still the canonical way to develop, but much of the repo now supports
|
|
development with Swift Package Manager.
|
|
|
|
### CocoaPods
|
|
|
|
Install the following:
|
|
* CocoaPods 1.12.0 (or later)
|
|
* [CocoaPods generate](https://github.com/square/cocoapods-generate)
|
|
|
|
For the pod that you want to develop:
|
|
|
|
```ruby
|
|
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](Firestore/README.md) Markdown file.
|
|
|
|
#### 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
|
|
|
|
Alternatively, disable signing in each target:
|
|
* Go to Build Settings tab
|
|
* Click `+`
|
|
* Select `Add User-Defined Setting`
|
|
* Add `CODE_SIGNING_REQUIRED` setting with a value of `NO`
|
|
|
|
### Swift Package Manager
|
|
* To enable test schemes: `./scripts/setup_spm_tests.sh`
|
|
* `open Package.swift` or double click `Package.swift` in Finder.
|
|
* Xcode will open the project
|
|
* Choose a scheme for a library to build or test suite to run
|
|
* Choose a target platform by selecting the run destination along with the scheme
|
|
|
|
### Adding a New Firebase Pod
|
|
|
|
Refer to [AddNewPod](AddNewPod.md) Markdown file for details.
|
|
|
|
### Managing Headers and Imports
|
|
|
|
For information about managing headers and imports, see [HeadersImports](HeadersImports.md) Markdown file.
|
|
|
|
### Code Formatting
|
|
|
|
To ensure that the code is formatted consistently, run the script
|
|
[./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/main/scripts/check.sh)
|
|
before creating a pull request (PR).
|
|
|
|
GitHub Actions will verify that any code changes are done in a style-compliant
|
|
way. Install `clang-format` and `mint`:
|
|
|
|
```console
|
|
brew install clang-format@18
|
|
brew install mint
|
|
```
|
|
|
|
### Running Unit Tests
|
|
|
|
Select a scheme and press Command-u to build a component and run its unit tests.
|
|
|
|
### Running Sample Apps
|
|
To run the sample apps and integration tests, you'll need a valid
|
|
`GoogleService-Info.plist
|
|
` file. The Firebase Xcode project contains dummy plist
|
|
files without real values, but they 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 add it to the Xcode project.
|
|
|
|
### Coverage Report Generation
|
|
|
|
For coverage report generation instructions, see [scripts/code_coverage_report/README](scripts/code_coverage_report/README.md) Markdown file.
|
|
|
|
## Specific Component Instructions
|
|
See the sections below for any special instructions for those components.
|
|
|
|
### Firebase Auth
|
|
|
|
For specific Firebase Auth development, refer to the [Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
|
|
building and running the FirebaseAuth pod along with various samples and tests.
|
|
|
|
### Firebase Database
|
|
|
|
The Firebase Database Integration tests can be run against a locally running Database Emulator
|
|
or against a production instance.
|
|
|
|
To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before
|
|
running the integration test.
|
|
|
|
To run against a production instance, provide a valid `GoogleServices-Info.plist` and copy it to
|
|
`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to
|
|
[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are
|
|
running.
|
|
|
|
### Firebase Dynamic Links
|
|
|
|
Firebase Dynamic Links is **deprecated** and should not be used in new projects. The service will shut down on August 25, 2025.
|
|
|
|
Please see our [Dynamic Links Deprecation FAQ documentation](https://firebase.google.com/support/dynamic-links-faq) for more guidance.
|
|
|
|
### Firebase Performance Monitoring
|
|
|
|
For specific Firebase Performance Monitoring development, see
|
|
[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK
|
|
and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about
|
|
integrating Performance with the dev test App.
|
|
|
|
### Firebase Storage
|
|
|
|
To run the Storage Integration tests, follow the instructions in
|
|
[StorageIntegration.swift](FirebaseStorage/Tests/Integration/StorageIntegration.swift).
|
|
|
|
#### Push Notifications
|
|
|
|
Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
|
|
In order to 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.
|
|
To receive push notifications, follow the steps above and run the app on a physical device.
|
|
|
|
### Vertex AI for Firebase
|
|
|
|
See the [Vertex AI for Firebase README](FirebaseVertexAI#development) for
|
|
instructions about building and testing the SDK.
|
|
|
|
## Building with Firebase on Apple platforms
|
|
|
|
Firebase provides official beta support for macOS, Catalyst, and tvOS. visionOS and watchOS
|
|
are community supported. Thanks to community contributions for many of the multi-platform PRs.
|
|
|
|
At this time, most of Firebase's products are available across Apple platforms. There are still
|
|
a few gaps, especially on visionOS and watchOS. For details about the current support matrix, see
|
|
[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform)
|
|
in Firebase's documentation.
|
|
|
|
### visionOS
|
|
|
|
Where supported, visionOS works as expected with the exception of Firestore via Swift Package
|
|
Manager where it is required to use the source distribution.
|
|
|
|
To enable the Firestore source distribution, quit Xcode and open the desired
|
|
project from the command line with the `FIREBASE_SOURCE_FIRESTORE` environment
|
|
variable: `open --env FIREBASE_SOURCE_FIRESTORE /path/to/project.xcodeproj`.
|
|
To go back to using the binary distribution of Firestore, quit Xcode and open
|
|
Xcode like normal, without the environment variable.
|
|
|
|
### watchOS
|
|
Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and
|
|
work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample).
|
|
|
|
Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit
|
|
test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected
|
|
on watchOS. 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 watchOS.
|
|
**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
|
|
|
|
#### Additional Crashlytics Notes
|
|
* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are
|
|
not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded)
|
|
|
|
## Combine
|
|
Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine
|
|
framework. This module is currently under development and not yet supported for use in production
|
|
environments. For more details, please refer to the [docs](FirebaseCombineSwift/README.md).
|
|
|
