firebase-ios-sdk: The Standard for iOS App Development: Firebase SDK Source Code Released
firebase/firebase-ios-sdk
About the project
It contains the official source code for Firebase services on Apple platforms. You can directly view the implementations of 13 major modules essential for app development, including Authentication, Database, Messaging, and Crash Reporting.
Installation is supported via Swift Package Manager and CocoaPods. Since new version releases for CocoaPods will cease in October 2026, adopting SPM should be considered. The Gemini Foundation Models framework adapter is available in preview, allowing you to test AI Logic features in advance.
macOS, Catalyst, and tvOS are in beta support, while visionOS and watchOS are community-supported. Firebase Analytics is not open source but is provided as a binary alongside other modules, making the rest useful for iOS developers who need to modify source code or debug.
