What functionality did you want to implement ? Firebase CloudMessaging or Firebase Crashlytics or both of them ?

Wanted to implement Firebase Crashlytics..

And i have commented the below line as new Xamarin.Firebase.iOSCrashlytics(4.6.2) doesn't need it.

In AppDelegate.cs //Crashlytics.Configure();

It seems Firebase.Core.App.Configure(); is also needed , did you add it ?

Yeah i tried that, But the app crashes with below message.

Error:
Objective-C exception thrown. Name: com.firebase.core Reason: Default app has already been configured.

Ensure that you call Firebase.Core.App.Configure(); only once in your project .

I test with Xamarin.Firebase.iOS.Crashlytics 4.6.2 , it works without any error .

I have done something like this
if(Firebase.Core.App.DefaultInstance == null) {
Firebase.Core.App.Configure();
}

But i don't think "Firebase.Core.App.Configure();" will be executed.

Replace

if(Firebase.Core.App.DefaultInstance == null) { Firebase.Core.App.Configure(); }

With

Firebase.Core.App.Configure();

HI @Cole Xia (Shanghai Wicresoft Co,.Ltd.)
As you told me to call 'Firebase.Core.App.Configure()' only once in the project, i added an if check.

And as i already told, if i just add 'Firebase.Core.App.Configure();' without the null check app will crash with below exception.

Exception:
Objective-C exception thrown. Name: com.firebase.core Reason: Default app has already been configured.
