I made a binding from a objective-c framework, it is working correctly but when I try to link my Xamarin.iOS project (Link Framework SDKs Only), I get this error
MTOUCH: Error MT5211: Native linking failed, undefined Objective-C class: GLKView. The symbol 'OBJC_CLASS$_GLKView' could not be found in any of the libraries or frameworks linked with your application. (MT5211)
In the microsoft documentation, says to add the [Protocol] attribute to the binding project.
I tried to add the attribute in the ApiDefinition.cs, first on top of the class and then before all methods and interfaces the classe have, with no success.
