FirebaseUI is an open-source library for iOS that allows you to quickly connect common UI elements to the Firebase database for data storage, allowing views to be updated in realtime as they change, and providing simple interfaces for common tasks like displaying lists or collections of items.

Additionally, FirebaseUI provides modern SwiftUI authentication components that simplify Firebase authentication by integrating with common identity providers like Facebook, Twitter, Google, and Apple.

FirebaseUI clients are also available for Android and web.

FirebaseUI supports iOS 17.0+ and Xcode 15+.

For SwiftUI authentication and modern features, use Swift Package Manager:

1. In Xcode, go to File > Add Package Dependencies
2. Enter the repository URL: https://github.com/firebase/FirebaseUI-iOS
3. Select the modules you need:
   • FirebaseAuthSwiftUI - Core SwiftUI authentication
   • FirebaseGoogleSwiftUI - Google Sign-In
   • FirebaseFacebookSwiftUI - Facebook Login
   • FirebasePhoneAuthSwiftUI - Phone Authentication
   • FirebaseAppleSwiftUI - Sign in with Apple
   • FirebaseTwitterSwiftUI - Twitter Login
   • FirebaseOAuthSwiftUI - Generic OAuth providers

For UIKit data binding features (Database, Firestore, Storage), use CocoaPods:

# Only pull in Firestore features
pod 'FirebaseUI/Firestore'

# Only pull in Database features
pod 'FirebaseUI/Database'

# Only pull in Storage features
pod 'FirebaseUI/Storage'

If you're including FirebaseUI in a project, make sure you also have:

platform :ios, '13.0'
use_frameworks!

The READMEs for components of FirebaseUI can be found in their respective project folders.

• SwiftUI Authentication

• Database
• Firestore
• Storage

If you'd like to contribute to FirebaseUI for iOS, you'll need to run the following commands to get your environment set up:

$ git clone https://github.com/firebase/FirebaseUI-iOS.git
$ cd FirebaseUI-iOS

# For SwiftUI components (uses Swift Package Manager)
$ cd samples/swiftui/FirebaseSwiftUISample
$ open FirebaseSwiftUISample.xcodeproj

# For UIKit data binding components (uses CocoaPods)
$ cd FirebaseDatabaseUI # or FirebaseFirestoreUI, FirebaseStorageUI
$ pod install

FirebaseUI includes several sample projects demonstrating different features:

Located in samples/swiftui/FirebaseSwiftUISample/, this sample demonstrates the modern SwiftUI authentication components.

Configuration:

1. Download GoogleService-Info.plist from Firebase Console
2. Copy it to the sample project folder
3. Update URL Types (for OAuth providers) in Project Settings -> Info tab -> Url Types:
   • REVERSED_CLIENT_ID (from GoogleService-Info.plist) - Required for Google Sign-In
   • fb{your-app-id} - Required for Facebook Login
4. For Facebook Login, update Info.plist with FacebookAppID and enable Keychain Sharing

Located in samples/objc/ and samples/swift/, these samples demonstrate FirebaseUI's data binding capabilities for Realtime Database and Storage.

Configuration:

1. Download GoogleService-Info.plist from Firebase Console
2. Copy it to samples/objc/GoogleService-Info.plist or samples/swift/GoogleService-Info.plist
3. Run pod install in the sample directory
4. Configure your Firebase Database and Storage in the Firebase Console
5. For the Chat sample, enable anonymous authentication in Firebase Console
6. For the Storage sample, configure appropriate Storage Security Rules
