[Bug] Crash on iOS 12 (happens on 50%+ of sessions) #820

Closed UlulabDev closed 1 year ago

UlulabDev commented 1 year ago

[REQUIRED] Please fill in the following fields:

[REQUIRED] Please describe the issue here:

Since our last app update, we are getting a lot of crash reports from Apple. Crashlytics and our own custom crash handling system don't see this crash, so it went undetected for months. As the call stack shows, it happens in the awake of a manager class so it's really early on in the lifecycle of a session. This crash only occurs for iOS 12 - further iOS versions never trigger this issue. We are getting more reports recently of iPads on iOS 16 hanging, but we don't know if this is related to this issue or not.

At least 50% of sessions on iOS 12 have got this crash, so it's pretty critical.

Unfortunately I don't have a good explanation as to why this crash started with this version only. We resolved dependencies in Unity to update the version of a different package (RevenueCat), and that did update the ExternalDependencyManager from version 1.2.175 to version 1.2.176. Not sure which libraries were changed on iOS as a result of this though.

The call stack seems to point to firebase. So my best guess is that this change in dependency manager version got another version of iOS libraries, which now causes the crash.

Steps to reproduce:

Open the app and it crashes.

We will soon be getting a device that can run iOS 12 to try and repro, but we don't have one at the moment so we can't repro. So far these statistics are coming from App Store Connect.

Built with XCode version 13.4.1

Relevant Code:

This is the code in our Awake function which is part of the callstack below:
private void Awake()
    {
        // This should not be necessary as it is supposed to be true by default.
        // It has been noted somewhere that never calling this may result in Firebase not working due to a bug.
        FirebaseAnalytics.SetAnalyticsCollectionEnabled(true);

        //From https://firebase.google.com/docs/unity/setup#confirm-google-play-version
        FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
        {
            var dependencyStatus = task.Result;
            if (dependencyStatus == DependencyStatus.Available)
            {
                // Create and hold a reference to your FirebaseApp,
                // where app is a Firebase.FirebaseApp property of your application class.
                app = FirebaseApp.DefaultInstance;

                delayedMessages.Enqueue("Firebase is Initialized");
            }
            else
            {
                delayedMessages.Enqueue($"Could not resolve all Firebase dependencies: {dependencyStatus}");
            }
        });
    }

Hi @UlulabDev,

Thanks for reporting this. It seems that you're already in touch with one of our engineers in another GitHub ticket. That said, I'll be closing this for now so that all discussion could be contained in one thread.
