How to read symbolicated crash log?

Question

Today my first app was rejected from testflight, because it crashed on start. But I cannot replicate it, because I do not have an Iphone, and in the simulator it works. I managed to symbolicate the crash log, but cant figure out how to read it. Could you please explain what this means and how it is read?

have to dump some text because its longer than the max. allowed post length:

Answer 1

So @sharkyenergy found the real bug: I am placing his solution above my suggestions:

"I developed on windows, but due to the pinch/zoom problem, i had to move to a mac. I didnt know that on mac you must add every nuget package to the.ios project too, while on windows they are shared. after adding all the packages it didnt crash anymore."

If his solution doesn't work for you, you can try the following below the line:

---

Things you can try,

1. While creating the archive, we use the Release-iPhone config, which is different from the Release-iPhone Simulator config. So when you are testing, you may not be testing the ACTUAL configuration. To check this, open the iOS Project Options in Visual Studio and compare all the settings to be the same (particularly the Linker behavior). Then test it on the simulator again and it could catch the error.

2. Occasionally your app can crash on launch in prod only, and the Microsoft AppCenter package can help you with this for free. Here's something you can add in the AppDelegate just when your FinishedLaunching function begins:

AppCenter.Start(Constants.AppCenteriOSKey, typeof(Analytics), typeof(Crashes));
if (Crashes.HasCrashedInLastSessionAsync().Result)
{
    ErrorReport crashReport = Crashes.GetLastSessionCrashReportAsync().Result;
    if (crashReport.StackTrace == null)
        Analytics.TrackEvent("AppCrashedInLastLaunch: Crash Report Trace is Null");
    else
    {
        var dict = new Dictionary<string, string>();
        dict.Add("CrashId", crashReport.Id);
        dict.Add("StackTrace", crashReport.StackTrace);
        Analytics.TrackEvent(string.Format("AppCrashedInLastLaunch: " + crashReport), dict);
    }
}
