I just upgraded from Xamarin 220.127.116.11 to Xamarin 18.104.22.168 and now I have random crashes when using my app with the iOS simulator with the debugger attached. It does not crash when using the iOS simulator without the debugger and it does not crash on the iPad with and without the debugger.
I have the following lines in the debug output of Visual Studio before crashing:
2017-04-27 11:11:47.131 Pelican[3873:68294] warning: mono_class_from_mono_type: implement me 0x74
