You specified .NET 8.0.3 as your current version, is that correct? There have been service releases. If you use that, does that work? You will need those for Xcode 15.4 compatibility. If you can create a reproduction project we can rule these things out. Thanks!

I am not the original poster, but I see this issue as well.

IOS 17.5.1, VS 17.10.6, MAUI workload 8.0.71, ios workload 17.5.8018. Note that I have Xcode 15.2, which the OP thought worked, but doesn't work for me.

My code is equivalent to:
string result = await Application.Current.MainPage.DisplayPromptAsync("blah", "blah");

The result of the call is nothing at all - it fails silently in Release mode. In debug mode, it doesn't reach the next line of code. I added a try/catch block, and no exception occurs.

I don't have a repro project for you, but I would expect that if you drop that line into a sample project, that is all that you would need to see the issue.

I tested this in IOS 17.6.1 without Xcode for me everything work stable
