Prevent dismissal of sheet in SwiftUI
I'd like to emulate the behavior of UIViewController.isModalInPresentation in SwiftUI. In my first attempt, I defined the following view: struct ModalView<Content: View>: UIViewControllerRepresentable { 		var content: () -> Content 		func makeUIViewController(context: Context) -> UIHostingController<Content> { 				let controller = UIHostingController(rootView: content()) 				controller.isModalInPresentation = true 				return controller 		} 		func updateUIViewController(_ imagePickerController: UIHostingController<Content>, context: Context) {} } From my main app view, I then present the ModalView as a sheet: struct ContentView: View { 		@State 		var presentSheet: Bool = true 		var body: some View { 				Text("Hello, world!") 						.sheet(isPresented: $presentSheet) { 								ModalView { 										Text("Sheet") 								} 						} 		} } But the user is still able to dismiss the ModalView by swiping down. I would expect this sheet to be non-dismissible. Is anything like this supposed to work? If not, is there some other way to prevent the dismissal of a sheet in SwiftUI? The closest workaround I've found is to apply .highPriorityGesture(DragGesture()) to the content of the sheet, but swiping down with two fingers still works.
