[firebase_auth] Firestore crash on user authentication on iOS

[GustavoDuregger]

Is there an existing issue for this?

• I have searched the existing issues.

Which plugins are affected?

Core, Auth, Other

Which platforms are affected?

iOS

Description

The application crashes after authentication. In the case where the user is already logged in, the failure occurs immediately after opening the app.

Crash logs mention problems with GRPC/SSL

This is happening in an installed Testflight application. I can't reproduce it in a simulator locally.

Reproducing the issue

Add firebase_auth: ^4.6.0; firebase_core: ^2.24.2; firebase_storage: ^11.2.0;
Run app in testflight
Authenticate the user via your preferred Google Sign In method
See that it crashes
Open the app again, see that it immediately crashes.

Firebase Core version

2.25.5

Flutter Version

3.19.1

Hi, your error message is exactly the same as mine. I use flutter for ios app.

A few days ago, my software department manager deployed the APP I developed and executed it according to the deployment process I wrote. Finally, this error occurred during the testflight test.

However, when I followed the deployment process, deployed and executed flutter build ipa on my other apple mac, and then ran the testflight test again, I found that there was no such error.

Therefore, I suspect that there may be a problem with the Xcode or cocoapods version that causes problems in building the ipa, or an exception occurs when the flutter package is installed into the ios package.

my cocoapods version:
1.15.2
XCode version:
Version 14.3.1 (14E300c)

  cached_network_image: ^3.3.1

Hi @GustavoDuregger, @Whaleman0423, this issue appears widespread among ReactNative users as well (see invertase/react-native-firebase#7695), indicating it might stem from the native library, potentially due to a migration to OpenSSL.

In the meantime, please consider upvoting firebase/firebase-ios-sdk#12606 and sharing your crash report there for visibility.
