Fixes a crash where Firebase Auth's Apple Sign-In handler crashes with EXC_BAD_ACCESS on iOS/macOS when the completion handler is deallocated during async operations.

Specifically:

  • Captures appleCompletion locally within handleSignInWithApple to prevent deallocation
  • Adds nil check before calling the completion handler
  • Creates strong references for callbacks in async operations

Affects both iOS and macOS platforms through the shared implementation.

Closes #17216.
