Is there a setting am I missing or Simulator is just broken on Beta 2 and won't go on the Internet? Xcode 12.4 is working fine. Other devs see this as well. Nothing in the release notes. Any workaround?

I cannot find how to opt-out some textfield and secure text fields (which for content type isn't even set) so that password autofill won't show up. Of course, Mac documentation is almost non-existent on the subject.

I don't know if this is a Xcode bug but all my projects just stop debugging with a SIGCONT message. I can still resume them but this is annoying. I can even reproduce the issue by creating a new Mac app with the basic project template and it'll SIGCONT as soon as I start debugging.

When creating a new SwiftUI project (either Xcode 12 or 12.2) and selecting both CoreData and CloudKit options, running the app on an iOS device shows absolutely nothing. This is not the case if creating a universal project and running it on macOS, which works and shows some UI. It's just a blank screen on iOS.

Hi! What is wrong with this code and why does this work for a Picker but not a List? struct ContentView: View {     enum FooBar: CaseIterable, Identifiable {         public var id : String { UUID().uuidString }                 case foo         case bar         case buzz         case bizz     }     @State var selectedFooBar: FooBar = .bar     var body: some View {         VStack {             Picker("Select", selection: $selectedFooBar) {                 ForEach(FooBar.allCases) { item in                     Text(self.string(from: item)).tag(item)                 }             }                         List(FooBar.allCases, selection: $selectedFooBar) { item in                 Text(self.string(from: item)).tag(item)             }                         Text("You selected: \(self.string(from: selectedFooBar))")         }     }     private func string(from item: FooBar) -> String {         var str = ""                  switch item {         case .foo:             str = "Foo"                      case .bar:             str = "Bar"                      case .buzz:             str = "Buzz"                      case .bizz:             str = "Bizz"         }         return str     } }

Since iPadOS 13, hitting Command-Q on a hardware keyboard is no longer triggering `UIKeyCommands` or is even ignored by `pressesBegan` and its siblings.Is there a way for an app to get this shortcut back?

I'm sure it's something very silly but how should one reset the state value of a child view when another state has changed?For example, the code below shows 2 folders, which respectively have 2 and 3 items., which can be edited.If you select the second folder (Work) and its 3rd item (Peter) and then select the first folder (Home), the app crashes since `selectedItemIndex` is out of bounds.I tried to "reset" the state value when the view gets initialized but it seems like changing the state like such triggers out a "runtime: SwiftUI: Modifying state during view update, this will cause undefined behavior." warning.init(items: Binding<[Item]>) { self._items = items self._selectedItemIndex = State(wrappedValue: 0) }What is the proper way to do this? Thanks!Here's the code:AppDelegate.swiftimport Cocoa import SwiftUI @NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate { var window: NSWindow! func applicationDidFinishLaunching(_ aNotification: Notification) { // Create the SwiftUI view that provides the window contents. let store = ItemStore() let contentView = ContentView(store: store) // Create the window and set the content view. window = NSWindow( contentRect: NSRect(x: 0, y: 0, width: 480, height: 300), styleMask: [.titled, .closable, .miniaturizable, .resizable, .fullSizeContentView], backing: .buffered, defer: false) window.center() window.setFrameAutosaveName("Main Window") window.contentView = NSHostingView(rootView: contentView) window.makeKeyAndOrderFront(nil) } func applicationWillTerminate(_ aNotification: Notification) { // Insert code here to tear down your application } }ContentView.swiftimport SwiftUI final class ItemStore: ObservableObject { @Published var data: [Folder] = [Folder(name: "Home", items: [Item(name: "Mark"), Item(name: "Vincent")]), Folder(name: "Work", items:[Item(name: "Joseph"), Item(name: "Phil"), Item(name: "Peter")])] } struct Folder: Identifiable { var id = UUID() var name: String var items: [Item] } struct Item: Identifiable { static func == (lhs: Item, rhs: Item) -> Bool { return true } var id = UUID() var name: String var content = Date().description init(name: String) { self.name = name } } struct ContentView: View { @ObservedObject var store: ItemStore @State var selectedFolderIndex: Int? var body: some View { HSplitView { // FOLDERS List(selection: $selectedFolderIndex) { Section(header: Text("Groups")) { ForEach(store.data.indexed(), id: \.1.id) { index, folder in Text(folder.name).tag(index) } }.collapsible(false) } .listStyle(SidebarListStyle()) // ITEMS if selectedFolderIndex != nil { ItemsView(items: $store.data[selectedFolderIndex!].items) } } .frame(minWidth: 800, maxWidth: .infinity, maxHeight: .infinity) } } struct ItemsView: View { @Binding var items: [Item] @State var selectedItemIndex: Int? var body: some View { HSplitView { List(selection: $selectedItemIndex) { ForEach(items.indexed(), id: \.1.id) { index, item in Text(item.name).tag(index) } } .frame(width: 300) if selectedItemIndex != nil { DetailView(item: $items[selectedItemIndex!]) .padding() .frame(minWidth: 200, maxHeight: .infinity) } } } } struct DetailView: View { @Binding var item: Item var body: some View { VStack { TextField("", text: $item.name) } } } struct IndexedCollection<Base: RandomAccessCollection>: RandomAccessCollection { typealias Index = Base.Index typealias Element = (index: Index, element: Base.Element) let base: Base var startIndex: Index { base.startIndex } var endIndex: Index { base.endIndex } func index(after i: Index) -> Index { base.index(after: i) } func index(before i: Index) -> Index { base.index(before: i) } func index(_ i: Index, offsetBy distance: Int) -> Index { base.index(i, offsetBy: distance) } subscript(position: Index) -> Element { (index: position, element: base[position]) } } extension RandomAccessCollection { func indexed() -> IndexedCollection<Self> { IndexedCollection(base: self) } }

So my app had its distribution certificate expired today. Usually, apps that were signed while the certificate was still valid should be unaffected and keep running. To my knowledge, this has been the case for years. You'd just then create a new certificate next time you wanted to push an update.However, and I'm not sure if this is a new restriction in macOS 10.15, but now my app will refuse to launch! You can imagine the support nightmare that will be."You should've pushed an update with a new certificate already!" you might say? Well what happens if some of your users don't run you app very often and they miss the update? Well they´re stuck with an app that no longer launches and have to redownload the updated app entirely instead of getting it via in-app updates.I don't know if this is a bug on Apple's end or this is now by design. If so, well this socks as this not only hurt developers that distribute their apps outside the MAS but users as well that rely on those apps and may find themselves unable to use the apps they need to get their work done until they figure out how to fix the problem or contact the developer for a solution.Anyone else had this issue?

Hi,My iOS Swift app contains a in-house built framework (A), which is also using Swift. This framework includes 2 in-house built frameworks (B and C) using Objective-C."Embedded Content Contains Swift Code" is set to YES for the app and to NO for the A, B and C frameworks.When I try to submit the app to iTC, I get these errors:ERROR ITMS-90205: "Invalid Bundle. The bundle at 'yourapp.app/Frameworks/A.framework' contains disallowed nested bundles."...ERROR ITMS-90206: "Invalid Bundle. The bundle at 'yourapp.app/Frameworks/A.framework' contains disallowed file 'Frameworks'."...How can I fix those?
