================================================================= Got a SIGSEGV while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries

used by your application.

I'm willing to bet that the problem is that you have a UIViewController or a button, that is defined within the scope of a method, like your Main, not realizing that it will present before being garbage collected and then, as soon as you do anything, it crashes like this.

I've had it happen a couple of times.
