User Profile

I have a SwiftUI application whose primary scene has the simplified definition: WindowGroup(id: someID, for: SomeModel.self) { $id in RootView(id: $id) } The body of RootView includes: someView .navigationTitle($title) .navigationDocument(model) The navigation title displays the correct value, however according to the documentation of the above modifiers, the navigation title should be editable and include a proxy icon. Neither of these is the case. RootView does not include a NavigationStack nor a NavigationSplitView. The Transferable implementation of the model is correct since drag & drop work fine. The UTType for the model conforms to public.content but not public.data since the model does not represent a file. Have I overlooked something in the implementation or is this a bug in the current beta? Xcode: Version 14.0 beta 6 (14A5294g), Feedback: FB11402796.
