title: AOT issue with mvvmcross
body: <p>I'm unable to build Xamarin projects that reference MvvmCross as I receive the error:</p>
  
  <p>Error MT3001: Could not AOT the assembly '/Users/chriskoiak/Documents/Initial/Mobile Clients/xxxx/obj/iPhone/Debug/mtouch-cache/Build/Cirrious.CrossCore.dll' (MT3001)
  Error MT3001: Could not AOT the assembly '/Users/chriskoiak/Documents/Initial/Mobile Clients/xxxx/obj/iPhone/Debug/mtouch-cache/Build/Cirrious.MvvmCross.dll' (MT3001)</p>
  
  <p>This error occurred after I upgraded to xcode5, mvvmcross 3.0.12 Xamarin.iOS 7.0.0.11</p>
  
  <p>Has anyone else experienced this problem or can suggest a fix?</p>
  
  <p>Thanks</p>
