Crashlytics not logging in iOS app

Question

Hi,

I have Xamarin Forms and I am trying to use Crashlytics. It works perfectly on my Android app but on iOS it does not log anything and I am not getting any error.

In my AppDelegate:

Firebase.Core.App.Configure();
Firebase.Crashlytics.Crashlytics.SharedInstance.SendUnsentReports();

Hello,

Welcome to our Microsoft Q&A platform!

You could try to add the following code, the Init method is necessary:

    Firebase.Core.App.Configure();  
    Crashlytics.SharedInstance.Init();  
    Crashlytics.SharedInstance.SetCrashlyticsCollectionEnabled(true);  
    Crashlytics.SharedInstance.SendUnsentReports();  

I test an out-of-bounds crash of an array.

private void Button_Clicked(object sender, EventArgs e)  
        {  
            var list = new List<string>  
            {  
                "11111",  
                "2",  
                "3",  
                "4",  
                "5",  
                "6",  
                "7",  
            };  
            for (int i = 0; i < 10; i++)  
            {  
                Console.WriteLine("{0}",list[i]);  
            }  
        }  

In the dashboard, I see an error " This app has 2 unprocessed crash issues. Please upload 2 dSYM files to handle the crash. " It means that the crash can be reported to Crashlytics Dashboard, but I didn't upload the dSYM files. You may not encounter this issue if you upload a dSYM file.
