Crash on production app

[shatodj]

Hi Touchlab,

I tried to implement CrashKiOS for our project and was successful when the app was built for development on iOS. In the production environment, there was a crash immediately after the app started.

Here is the error I picked up from the Console.

Scene FBSceneManager/sceneID:<APPBUNDLE>-default update failed: <NSError: 0x283a1ddd0; domain: FBSceneErrorDomain; code: 1 ("operation-failed"); "Scene update failed."> {
    NSUnderlyingError = <NSError: 0x283a1cba0; domain: FBWorkspaceScene; code: 1; "Client process exited.">;
}

I just have no clue where to look to solve the issue. Maybe you will be able to see the problem here. Thank you for the feedback.

Are you using CrashKiOS with crashlytics or bugsnag? We aren't initially sure what the issue is. Can you share any more context or a small reproducing project?

Did you solve the problem?

[shatodj]

Are you using CrashKiOS with crashlytics or bugsnag? We aren't initially sure what the issue is. Can you share any more context or a small reproducing project?

Thanks for your interest. We're using Crashlytics. Currently, we have decided to leave CrashkiOS since we are not able to solve it fast. I will provide a small project once I have more time. It's not trivial.

@dmikots not yet, sadly :(

[tomasjablonskis]

We have the same issue as well. Everything works until we upload app to TestFlight or App Store then it just crashes on start without any stacktrace to help us track it down.

[DmitriiVM]

And we are experiencing the same problem as described above.

[TadeasKriz]

Hey everyone, could you try running the app on your device/simulator in Release configuration? It should also crash and should give you a stack trace in Xcode. If you could share that, it'd help us finding a reproducer and a fix. Thank you!

[tomasjablonskis]

@TadeasKriz the funny thing is that it does not crash in any configuration or on any device until app is uploaded to TestFlight or App Store.

[TadeasKriz]

Just to doublecheck, following the steps below don't lead to a crash?

1. in Xcode click on the "Edit Scheme",
2. then in "Build" change configuration from "Debug" to "Release"
3. run on a device

Does not crash.

[TadeasKriz]

Can you check your "Run Phases" to see if any of them have "For install builds only" enabled?

[tomasjablonskis]

None of them have "For install builds only" enabled.

[TadeasKriz]

Thanks, that's good to know. Would you be able to tell us more about your specific project? What libraries do you use and how you have everything configured?

[tomasjablonskis]

Its a simple KMM project. We are consuming shared KMM module on iOS through Cocoapods. We do not have any custom configuration. SPM packages used:

• Alamofire 5.9.1
• TunnelKit 6.2.0
• SocketIO 16.1.0
• Siren 5.8.1
• Firebase 10.24.0
• Lottie 4.4.3

[TadeasKriz]

And on the Kotlin side, what dependencies do you use and how do you have CrashKiOS configured?
