Description kevinknoop 2014-04-03 04:11:17 UTC
I have attached a simple test case using the Layout DSL found here https://gist.github.com/praeclarum/5175100
This works 100% on Xamarin.iOS 7.2.0.
On Xamarin.iOS 7.2.1 this no longer works on a device. I get the exception below. It does however still work on the simulator. I understand JIT on the device is not possible but this does work with 7.2.0 hence me raising this issue.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Exception: Attempting to JIT compile method '(wrapper delegate-invoke) <Module>:invoke_callvirt_UIView_UIViewController (MonoTouch.UIKit.UIViewController)' while running with --aot-only. See http://docs.xamarin.com/ios/about/limitations for more information.
