[iOS] App exceptions on physical device, but works on the simulator #12503

Closed AndreasReitberger closed 11 months ago

AndreasReitberger commented 1 year ago

Description

I was facing a strange behaviour of my app. It was working fine while running on the simulator. However once I moved to a physical device (iPhone in my case), the app throws exceptions and crashes.

After a while I figured out, that a missing StaticResource, better a missing style, was the issue.

System.Reflection.TargetInvocationException: Position 165:45. StaticResource not found for key DefaultBorderlessEntry

Style="{StaticResource DefaultBorderlessEntry}"

It would have saved me a lot of headache if the Simulator would also throw an exception if a StaticResource is not found. Is there a way to adjust this?

@StephaneDelcroix seems like something you might know more about?

It would be even more awesome if the build task already sees that the StaticResource is not found. Like it works with CompiledBindings. https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/data-binding/compiled-bindings
