I am working currently on adapting our Email application written on Xamarin iOS to run correctly on Apple Silicon M1. I have faced the following problem that I can't solve so far. The problem is that our code written for iOS that uses UIDocumentInteractionController on Apple Silicon opens "Share to" menu, also if I try to change this to Launcher.OpenAsync() call from Xamarin.Essentials it also opens "Share to" menu instead of opening the file with default application. I tried to use Launcher.OpenAsync() from Xamarin.Mac application and run it directly on Apple Silicon from VS Mac and it works as expected this way - opens file with default application. However when running from iOS application installed on Apple Silicon it always opens "share to" menu. It is a big problem for us as we need to allow user to open attachments files from our email editor. Any ideas what I can try to do to solve the problem?
So in the end I replaced our UIDocumentInteractionController with Quick Look Preview Controller which works as expected both on iPhone and iOS application running on M1.
