After update to Visual Studio 2019 version 16.9, I started using Xcode Interface Builder to continue building your Xamarin.iOS user interfaces.
The problem is when I create new view controller in Xcode Interface Builder and InstantiateViewController, it return null. Before this update, I using Xamarin iOS designer ,it work fine.
Is there any way I can fix it?
Here some screenshot, for better view:-
