🐛 [firebase_auth] iOS crashes when signing in with Apple

[felixgabler]

Bug report

Describe the bug
When I try to sign in with my Apple ID using await _auth.signInWithProvider(appleProvider) the app crashes on iOS. On Android it works fine.

The console output:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[3]'

Steps to reproduce

Steps to reproduce the behavior:

1. Set up an apple provider with scopes 'email' and 'name' (but it also crashes without)

final appleProvider = auth.AppleAuthProvider()
      ..addScope('email')
      ..addScope('name');

2. Call FirebaseAuth.instance.signInWithProvider(appleProvider)
3. In the iOS dialog, select that you want to share name and use email relay
4. Use face ID or password to authorize the sign in with Apple
5. The app just crashes

Expected behavior

The app should sign me in with my Apple ID and return name and email in the userCredential.user.providerData.

Sample project

If required, I can take the time to set something up but for iOS I feel like it is super complicated with new App ID, Team ID etc. Or am I missing a simple way to share it?

Here is the relevant code I use (copied from my app).

Future<String?> signInWithApple() async {
    final appleProvider = AppleAuthProvider()
      ..addScope('email')
      ..addScope('name');
    final UserCredential userCredential;
    if (kIsWeb) {
      userCredential = await FirebaseAuth.instance.signInWithPopup(appleProvider);
    } else {
      userCredential = await FirebaseAuth.instance.signInWithProvider(appleProvider);
      // CRASHES HERE
    }

    // OTHER BUG: name and email are not returned on iOS
   return userCredential.user?.providerData.firstOrNull?.displayName;
}

---

Additional context

Tested both on a simulator and a real device. I always removed the Apple ID from the app between tests using the Apple ID settings. Also tried flutter clean and removing the scopes name and email.

The scopes actually also do not seem to work correctly with the new signInWithProvider (also not with linkWithProvider) in my testing with the previous version of this package. They do not return a name and email. Should I create another issue about this?

I previously used sign_in_with_apple but replaced it and set everything up according to https://firebase.google.com/docs/auth/flutter/federated-auth#ios. It works well for Android for both sign in and linking. It also returns the name and email correctly.

👍 - Also seeing the same issue and the same error.

One other test note: After app restart the auth object is valid and available. ie the auth user then exists in our app state on next restart. So crash occurs after successful login. Crash is critical closes app completely, doesn't just hang. Closing the dialog and not attempting to login does not crash.

Thanks for the report @felixgabler
Using the code sample provided, I am able to replicate this issue using latest plugin version and on stable version (3.3.3) which throws below error log:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[3]'

Also verified using previous plugin version (3.10.0) and replicates.

if you need a solution right now and it's urgent to work with apple sign in you can use firebase_auth: 3.9.0 it works perfectly

[Lyokone]

Thanks for the report, I'm looking into this

[felixgabler]

Does it also correctly return name and email according to the scopes? That's also a major blocker for us

[Lyokone]

@felixgabler If I'm not mistaken, for security reasons, Apple returns the Name and the Email only on the first sign-in, if you don't catch them at this time, you cannot retrieve them again. Might need to double-check that, but please open another PR concerning this issue.

yes it returns only for first sign-in

yes it does, but to mention for apple it returns email and fullname only in first sign in after that it returns null, so you should store them in secure storage if you want to reuse them

Thanks for looking into it again! I know that it doesn't work on subsequent logins but normally it works when I disconnect my apple ID in the apple ID settings (https://appleid.apple.com/account/manage). For example, it does work with sign in with apple on Android.

I was just curious whether you know if it broke somewhere between these versions.

Will open another issue later.

[Lyokone]

I've opened #9644 that fixes the issue, will probably be merged and released early next week

[GeylanKalafMohe]

This need to be fixed as soon as possible! It's very urgent.

Does not work, unfortunately. Still crashes!

[Lyokone]

The fix was released in v3.11.1 thanks for your patience.
