Hi folks I'm playing with the new @AppStorage wrapper because I'm considering using it to store some simple application state data. I've created a custom class, which conforms to ObservableObject, and RawRepresentable, and it all works fine if I do all my work in a single view. If I invoke a subview, and pass in the @AppStorage object as an environmentObject, I can read data from it, but updates to the data never propagate back to the underlying storage. Here is a simplified reproducer, using the new @main/App lifecycle. I would be thrilled if anyone can help me figure out what's wrong: // //  ContentView.swift //  AppStorageTest // //  Created by Chris Jones on 25/06/2020. // import SwiftUI import Combine @main struct AppStorageTestApp: App {     var body: some Scene {         WindowGroup {             ContentView()         }     } } class Person: RawRepresentable, ObservableObject {     @Published var name: String     @Published var age: Int     // RawRepresentable     var rawValue: String {         get {             let value = "\(name):\(age)"             print("Returning raw value: "+value)             return value         }     }     required init?(rawValue: String) {         if rawValue == "" {             print("Initialised with empty rawValue, setting defaults")             self.name = "Jonny Appleseed"             self.age = 42             return         }         print("Initialising with rawValue: \(rawValue)")         let parts = rawValue.split(separator: ":")         self.name = String(parts[0])         self.age = Int(parts[1])!     } } struct ContentView: View {     @AppStorage("person") var person: Person = Person(rawValue: "")!     var body: some View {         // Swap this subview out for the VStack{} from ContentSubview and this all works         ContentSubview().environmentObject(person)     } } struct ContentSubview: View {     @EnvironmentObject var person: Person     var body: some View {         VStack {             TextField("Name: ", text: $person.name).padding()             TextField("Age: ", value: $person.age, formatter: NumberFormatter()).padding()         }     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView().environmentObject(Person(rawValue: "")!)     } }

I've just upgraded to Xcode 12 beta 3 and my app, which was building fine on beta 2 now fails to build with the error: 'init(selection:content:)' is unavailable in watchOS which refers to a call of the form List(selection: $someBinding) { SomeContentHere() } The docs seem to suggest that this initialiser is supposed to be available for watchOS. Is anyone else seeing this?

I'm trying to add QuickLook previews to a SwiftUI app which uses Table(). I've added the .quickLookPreview() modifier to my Table(), and added a menu command for invoking it, and if I select that menu item manually, it works fine, but I have two keyboard related issues which are making it difficult to actually ship this functionality: When using the .quickLookPreview() variant for a set of URLs, keyboard navigation between the quicklook previews only works with left/right arrows, but being invoked by a Table, it would make much more sense for up/down arrows to navigate through the previews I set a .keyboardShortcut() on the menu command to use Space, since that's the normally-expected shortcut for quicklook, and it doesn't work. If I set it to some random other key (like "a") it does work, but .space doesn't do anything.
