Displaying a subtitle for nested UIMenus
The sessions talks about a new subtitle ability for UIMenus (“These buttons also benefit from improvements in menus like the ability for menu items to have subtitles for greater clarity.”) but I cannot find documentation on how to enable said subtitle. Even using the example code with the new .singleSelection option does not display any subtitle.. Anyone did succeed in doing so?

Custom Container View with ForEach(subviews:content:)
Hi, I’m trying to implement a custom horiztonal Picker using the newly introduced API on ForEach like the following: struct ScopeBar<SelectionValue: Hashable, Content: View>: View { // MARK: Initializers @Binding private var selection: SelectionValue @ViewBuilder private var content: () -> Content public init(selection: Binding<SelectionValue>, @ViewBuilder content: @escaping () -> Content) { _selection = selection self.content = content } // MARK: Content var body: some View { ScrollView(.horizontal) { LazyHStack { ForEach(subviews: content()) { subview in Button { // selection = subview.id as! SelectionValue } label: { subview } .tag(subview.id) } } } } } The following implementation is what I’m trying to achieve for the custom container usage: struct MyOtherView: View { enum SomeScopes: String, CaseIterable, Hashable { case first case second case third case fourth case fifth } @State private var selection: SomeScopes = .first var body: some View { ScopeBar(selection: $selection) { ForEach(SomeScopes.allCases, id: \.rawValue) { scope in Text(scope.rawValue) } } } } I’m having some trouble figuring out two things: How can I make my SelectionValue equal to the Subview.ID so that my selection behaves internally like a Picker would? Say I wanted to add an Image(…) in addition to the Text(scope.rawValue), how would I do it in order for the Button { … } label: { … } to use both views, and not each separately…?
