I am not sure if this is because i updated Xamarin Forms or VS for Mac or what. But it looks like a Xamarin Forms issue.
But now in iOS when i launch my app on a simulator I get this weird exception that I've never seen before.
It happens during the splash screen:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Anybody else? Any idea how to get it to work again?
Thanks!
