Firebase after version 12

From the Firebase migration page (last updated 13 October 2026):

• "Firebase 12 is the final major version published to CocoaPods, and Firebase will stop publishing new versions to CocoaPods in October 2026."
• The change covers 20 listed pods (Firebase, FirebaseAnalytics, FirebaseCore, FirebaseCrashlytics, FirebaseMessaging and others) "and their subdependencies".
• Existing versions, 12 and earlier, stay installable. New features and fixes ship through Swift Package Manager and the manual XCFramework download only.

What podexit shows

The listed pods are capped at 12.x. Pods they depend on (FirebaseCoreInternal, FirebaseSessions, GoogleUtilities, nanopb and so on) are capped with Firebase, with the listed pod that pulls them in. From the native-app fixture:

FirebaseAnalytics     12.19.0  capped at 12.x        yes (Firebase)
FirebaseCoreInternal  12.19.0  capped with Firebase  yes             FirebaseCore
GoogleUtilities       8.1.4    capped with Firebase  yes             AppCheckCore +8
Copy

The list of pods, the version cap, the date and the source URL live in data/publisher-policy.json; every entry must cite its source.

Native apps

1. In Xcode, add https://github.com/firebase/firebase-ios-sdk as a package dependency.
2. Add the products you used as pods (FirebaseAnalytics, FirebaseCrashlytics, …) to your app target. The package brings GoogleAppMeasurement, GoogleUtilities, GoogleDataTransport, nanopb and Promises itself.
3. Remove the Firebase pods from the Podfile and run pod install.

If some of your other dependencies cannot leave CocoaPods yet, Firebase recommends the manual XCFramework installation over mixing CocoaPods and Swift Package Manager in one target.

Flutter and React Native

• FlutterFire: Firebase says updating to the latest FlutterFire moves the Apple side to Swift Package Manager automatically. See Flutter apps and plugins.
• React Native Firebase: version 26 declares the Firebase SDK with spm_dependency, so its lockfile has no Firebase pods (see the rn-app fixture). See React Native and Expo.

Staying on CocoaPods for now

Firebase 12 keeps installing. Pin the version you test with (pod 'FirebaseAnalytics', '~> 12.19') so a pod update does not surprise you, and plan the move: fixes after October 2026 will not reach it.
