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…?

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?
