Xamarin.iOS app crashes on startup on iOS13 on Testflight

Question

I have tested the application on Testflight and as soon as I open it everything works correctly. The problem comes when I close the app and open it again, at that moment the application crashed and does not let me open it anymore.

I am testing on my iphone 6s with iOS 13.1.3.

Can anyone help me, please?

Answer 1

The App Center SDKs work well for capturing crash information. You can then see it in the App Center Portal

Answer 2

I have already added AppCenter to the project, and now I can see the analytics, but it doesn't catch me crash error.

About the configuration of AppCenter, I have added to the AppDelegate.cs (FinishedLaunching)

AppCenter.Start("bxxxxxxxxxxxxxxxxxxxxxxxxxxx3a0",
                   typeof(Analytics), typeof(Crashes));
Crashes.NotifyUserConfirmation(UserConfirmation.AlwaysSend);

Crashes.SetEnabledAsync(true);

And to the App.xaml.cs

AppCenter.LogLevel = LogLevel.Verbose;
AppCenter.Start("ios=b41cxxxxxxxxxxxxxxxxxxxxxxxxxx0;" +
                  "uwp={Your UWP App secret here};" +
                  "android={Your Android App secret here}",
                  typeof(Analytics), typeof(Crashes));
Crashes.NotifyUserConfirmation(UserConfirmation.AlwaysSend);

I test the Crashes.GenerateTestCrash on the simulator and It works, but exaclty the iPhone crash no
