Specified cast is not valid error while using "SignInWithCredential".

[remeesms]

While using "SignInWithCredential" the app is crashing with "Specified cast is not valid " error.
Its happening after updating the firebase auth to version="6.2.1". Previously The "SignInAndRetrieveDataWithCredential" was working perfect.

Firebase versions using:

  <package id="Xamarin.Firebase.iOS.Analytics" version="5.1.4.1" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.Auth" version="6.2.1" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.CloudMessaging" version="4.1.1.1" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.Core" version="6.1.0" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.Database" version="6.0.0" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.InstanceID" version="4.2.1" targetFramework="xamarinios10" />
  <package id="Xamarin.Firebase.iOS.Storage" version="3.4.0" targetFramework="xamarinios10" />

Code Sample:

var credendtials = PhoneAuthProvider.DefaultInstance.GetCredential(verificationId, verificationCode);
Auth.DefaultInstance.SignInWithCredential(credential: credendtials, (task, error) =>
            {
                if (error != null)
                {                  
                    tcsPhone.SetResult(false);
                }
                else
                {
                    tcsPhone.SetResult(true);
                }

            });

Any update on this?

I'm also experiencing this same issue, although the login actually completes and if I restart the app then I'm logged in.

[remeesms]

@TonyPovey Yeah same behaviour here. @Redth Any update?

Guys, letting you know that a fix of this is in progress. Hope it will be released this week.

[remeesms]

Now it doesn't show this error but there is no return from SignInWithCredential. Is there any change need in the implementation?

[SotoiGhost]

@remeesms Nothing changed, we just changed the callback parameter type. If it seems to be failing, please, file a new issue describing the problem. Also, it would be great if you can provide a test case. Thanks in advance!

@SotoiGhost Filed a new issue here #337. Please have a look.
