I believe this also affects net7.0-maccatalyst, as I'm seeing the same issue when building under dotnet 7.0.309.

If you simply add the DisplayActionSheet to the OnCounterClicked handler of the standard Maui app the action sheet does not appear and following statements are not executed. On Windows and Android this works as expected. I also suddenly have in my app when running on MacCatalyst MenuBarItems in my XAML that do not respond when clicked. I have a feeling these problems are related.

private void OnCounterClicked(object sender, EventArgs e)
{
	count++;

	this.DisplayActionSheet("What type of condition?", "Cancel", null, "Source Condition", "Position Condition", "Attribute Condition", "Affected By Condition");

    if (count == 1)
		CounterBtn.Text = $"Clicked {count} time";
	else
		CounterBtn.Text = $"Clicked {count} times";

	SemanticScreenReader.Announce(CounterBtn.Text);
}

I ran into the same issue, and was getting the following null reference exception, .NET 7.0.401

await Application.Current.MainPage.DisplayActionSheet("Title", "Cancel", null, "test", "test1", "test2");

When I run the standard Maui app described above, with or without the change, it outputs this message when it starts up. It seems DisplayActionSheet is getting called from somewhere and already reporting a problem.

I was seeing this message before I had issues with DisplayActionSheet, though.

[cdavidyoung]

Yes, but perhaps it was trying to tell us something. I would think that warning should be fixed in any case and perhaps it will resolve this problem.

@Matthewrbowker One more datapoint is that DisplayAlert seems to work fine. I suppose I could convert the DisplayActionSheet in my app to a series of DisplayAlert but that would be rather awkward. : ) Besides that, the other thing that is not working for me are MenuBarItems. I have a feeling that when DisplayActionSheet is fixed it will fix MenuBarItems as well.

[cdavidyoung]

@Matthewrbowker Here is another clue. My main development Mac is an M1 with the latest updates. I have an old Mac Mini 2014 available as well so I decided to try my app on it. Wouldn't you know it. The DisplayActionSheet and MenuBarItems work fine on it. Here are screenshots. Is there anything else I can do to help diagnose this?

[ultra133]

I can confirm this issue. A delivered program has suddenly stopped working. On a computer with Sonoma 14.1 installed, DisplayActionSheet no longer runs and no action sheet is displayed. On an older computer with Ventura 13.6.1, no error occurs and the action sheet is displayed.

[mwnovaprove]

Same issue here, with Sonoma 14.1 installed. Is there any workaround or are we forced to wait for an hotfix?

[ultra133]

Since calling an action sheet with UIKit is really a no-brainer, this could be an easy workaround for those who can't wait for a fix:

#if MACCATALYST
        if ((Handler as PageHandler)?.ViewController is not UIViewController viewController) return;

        var completion = new TaskCompletionSource<string>();

        var alert = UIAlertController.Create("Caption", null, UIAlertControllerStyle.ActionSheet);
        alert.AddAction(UIAlertAction.Create("Cancel", UIAlertActionStyle.Cancel, _ => completion.TrySetResult("Cancel")));
        alert.AddAction(UIAlertAction.Create("One", UIAlertActionStyle.Default, _ => completion.TrySetResult("One")));
        alert.AddAction(UIAlertAction.Create("Two", UIAlertActionStyle.Default, _ => completion.TrySetResult("Two")));
        alert.AddAction(UIAlertAction.Create("Three", UIAlertActionStyle.Default, _ => completion.TrySetResult("Three")));
        viewController.PresentViewController(alert, true, null);

        var result = await completion.Task;
#else
        var result = await DisplayActionSheet("Caption", "Cancel", null, "One", "Two", "Three");
#endif

PLEASE FIX THIS

This will impact any iOS apps published on the store that are set to be allowed to run on M-procesor Macs. So even if you haven't specifically released a Mac version of your app, your users may still be launching the iOS app on Mac and getting the crash.

It looks like there is a fix in progress in the PR #19629 which is good!
