This might not occur that often in your projects but if you find yourself dropping a MapView on your storyboard and then just running the app you will most certainly will experience a crash. Why?
- Make sure you have enabled Map services in your Info.plist file
- Make sure you give your MapView a name (that automagically creates an outlet)
If you don’t give your MapView a name then the Xamarin/Mono linker will not link in the MapKit framework due to it not being used in code.
