Auth

Which platforms are affected?

iOS

Description

A crash is happening when trying to sign in with Apple on my iOS live app with firebase_auth and using the AppleAuthProvider class.

Reproducing the issue

I have no idea how to reproduce it since it happened only to my live users and i have tested the Sign in With Apple multiple times after without any success to reproduce the issue...

Here is the code i am calling in my released app to sign in with Apple :

Future<bool> signInWithApple() async {
    AppleAuthProvider appleAuthProvider = AppleAuthProvider();
    appleAuthProvider.addScope("email");
    appleAuthProvider.addScope("fullName");
    try {
       UserCredential? userCredential = await FirebaseAuth.instance.signInWithProvider(appleAuthProvider);
       return userCredential != null;
    } catch (error) {
       print("Error sign in with Apple $error");
    }
    return false;
}

Firebase Core version

3.8.1

Flutter Version

3.24.5

So far i have received 4 crashes on 4 different phones :

[stx]

Same issue.

Crashing on handleSignInWithApple (FLTFirebaseAuthPlugin.m) on this line

object.appleCompletion(nil, [FLTFirebaseAuthPlugin convertToFlutterError:error]);

[SelaseKay]

Could you please provide a complete example to help reproduce this issue? I’m unable to replicate it on my end.

[Tom3652]

In my latest release i have no more this crash which includes the latest firebase_auth version.
I can't say it's fixed but i had crashes for few months and suddenly i have not.

I wish i had a reproductible code sample but no, maybe it's fixed and i can update here if i see a new crash later.

[SelaseKay]

Sure. I'll go ahead and close this issue in the meantime.
