I have two projects. The first one is the iOS-App which is referencing a class library with the target framework "Xamarin.iOS". In that class library I implemented a CustomView which inherits from UIView. I also registered it with the "Register" attribute.
So in the interface designer I get the prefilled information to use this class as custom class after I dragged the UIView to my ViewController. But when I run the app I get the following information: "Unknown class MyCustomView in Interface Builder file."
If I move the my CustomView from the class library project into my first project then it will run as expected.
Does someone know how to use a CustomView, which is located in a referenced class library, in an Interface Builder file?
