Getting System.TypeInitializationException: The type initializer for 'IOS' threw an exception in iOS 13 after updating Visual studio and macOS

[divyesh008]

Xamarin.Auth Issue

Note: I have added --optimize=force-rejected-types-removal in additional mtouch argument with linker behavior Link from sdk only to forcefully remove trace of deprecated UIWebView.

When code executes this line:

rc.PresentViewController(auth.GetUI(), true, null);

var presenter = new Xamarin.Auth.Presenters.OAuthLoginPresenter();
presenter.Login(auth);

IF BUG, INCLUDE THIS PART:

Version

• nuget version = 1.7.0
• component version =
• sample

Steps to reproduce

1. Perform authentication steps as mentioned in this nuget's readme
2. Add --optimize=force-rejected-types-removal mtouch argument with Link from sdk only linker behavior
3. Execute: rc.PresentViewController(auth.GetUI(), true, null);

Platform:

• [] .NET version = .NET Core Runtime: 3.1.6 / .NET Core SDK: 3.1.302
• [] mono version = 6.10.0.106
• Xamarin.iOS Version: 13.18.3.2 (Visual Studio Community)

Expected behaviour

LinkedIn, Insta and Facebook login succeeds

Actual behaviour
