Hi 🙂

The issue was on iPhone5S with iOS 8.02

error:

Unhandled Exception: System.ExecutionEngineException: Attempting to JIT compile method ‘(wrapper dynamic-method) System.Runtime.CompilerServices.ExecutionScope:lambda_method (System.Runtime.CompilerServices.ExecutionScope,object,object,object,object)’ while running with –aot-only.

As far as I know the “System.Reflection.Emit” api is available in mono but does not work on iOS.
You can use reflection on iOS but there is no way to compile code at runtime. And I think that “System.Reflection.Emit.DynamicMethod.CreateDelegate” does this. But I am not a .net Reflection Pro!

Cheers! 🙂
