Description

Adding firebase_core and firebase_crashlytics to an existing project, failed to build iOS app:

Lexical or Preprocessor Issue (Xcode): Include of non-modular header inside framework module 'firebase_crashlytics.Crashlytics_Platform':
'/Users/sunbro/dev/my_app/ios/Pods/Headers/Public/Firebase/Firebase.h'
/Users/sunbro/.puro/shared/pub_cache/hosted/pub.dev/firebase_crashlytics-4.1.2/ios/Classes/Crashlytics_Platform.h:20:8

Lexical or Preprocessor Issue (Xcode): Include of non-modular header inside framework module 'firebase_crashlytics.ExceptionModel_Platform':
'/Users/sunbro/dev/my_app/ios/Pods/Headers/Public/Firebase/Firebase.h'
/Users/sunbro/.puro/shared/pub_cache/hosted/pub.dev/firebase_crashlytics-4.1.2/ios/Classes/ExceptionModel_Platform.h:20:8

Reproducing the issue

• using latest stable flutter (3.24.3)
• using latest XCode 16 (16A242d)
• adding firebase [core & crashlytics] to the app
• using flutterfire cli to setup the app with multiple flavor (will also fail if only using a single ios flavor/schema)
• running flutter build ios

Firebase Core version

3.5.0

Flutter Version

3.24.3

Additional context and comments

setup up was done via the flutterfire cli:

flutterfire configure -o "lib/firebase/firebase_options_dev.dart" --platforms "ios" -i "<my.bundle.Id>.dev" --ios-build-config "Release-dev" --ios-out "ios/dev"
flutterfire configure -o "lib/firebase/firebase_options_stage.dart" --platforms "ios" -i "<my.bundle.Id>.stage" --ios-build-config "Release-stage" --ios-out "ios/stage"
flutterfire configure -o "lib/firebase/firebase_options_prod.dart" --platforms "ios" -i "<my.bundle.Id>" --ios-build-config "Release-prod" --ios-out "ios/prod"

Set minimum deployment target to 13 (in XCode and in Flutter/AppFrameworkInfo.plist)

I made sure that everything is up-to-date

flutterfire configure
flutterfire update
flutter clean && flutter pub get
cd ios && pod install --clean-install
