Missing Package Reference in NativeDialog sample app

When attempting to build this sample app to iOS, get following error:

../Fuse.Dialogs/Dialogs.uno(44.22): E3104: Fuse.Scripting.Context does not contain a member called 'Dispatcher'. Could you be missing a package reference?

So the readme states that this sample app is meant only for Android.

Not sure why the an iOS routing wasn’t set up to print something like ‘Not supported on this platform’ as was illustrated in the Youtube Foreign Code tutorial.
