ShareLink and DataRepresentation
In my app, I'd like to be able to share a .csv file via ShareLink and Transferable. I watched the "Meet Transferable" WWDC22 video and it should be possible as the presenter demonstrated that use case. However, when I try this on my end, I am able to share the content but somehow it is treated by iOS as plaintext and when sharing by email or messages, it will just add the text content to the body. If I try to share via AirDrop, it creates a random filename with the .txt extension even though I specify .commaSeparatedText. The only way this somewhat works is when saving to files. It will save as a .csv file but the filename is set to "comma-separated values". Here's some code: struct MyArchive {     enum ValidationError: Error {         case invalid     }     var filename: String { return "myarchive.csv"     }          init(csvData: Data) throws {         //...     }     func convertToCSV() throws -> Data {         let test = "Name,Email\nPete,pete@example.com"         if let data = test.data(using: .utf8) {             return data         }         else {             throw ValidationError.invalid         }     }  } extension MyArchive: Transferable {     static var transferRepresentation: some TransferRepresentation {         DataRepresentation(contentType: .commaSeparatedText) { archive in             try archive.convertToCSV()         } importing: { data in             try MyArchive(csvData: data)         }     } } And in my View: struct View: View { var body: some View { //... let csv = MyArchive() ShareLink( item: csv, preview: SharePreview(                         csv.filename,                         image: Image(systemName: "doc.plaintext")                     ) ) } } I'm at the point that I wonder if I'm doing something wrong or this just doesn't work in iOS 16 beta 1. Any hints? Thanks!

SwiftUI window aspect ratio
Is there a way to force a window to resize according to an aspect ratio? This is possible in AppKit via the NSWindow.contentAspectRatio property but I cannot find something similar for SwiftUI. Basically, I want the window to maintain the aspect ratio of its contents.

SwiftUI toolbar item keyboard shortcut not showing when holding command key on iPad?
How come keyboard shortcuts associated to toolbar items do not show up when you hold down the command key? import SwiftUI struct ContentView: View { var body: some View { NavigationStack { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") Button { } label: { Text("Tap Me!") } .keyboardShortcut("o", modifiers: .command) } .padding() .toolbar { ToolbarItem { Button { } label: { Image(systemName: "bolt") } .keyboardShortcut("k", modifiers: .command) } } } } } See screenshot. The shortcut for "Tap Me!" is being shown but not the one for the toolbar item. Am I doing something wrong or this is just not supported yet in SwiftUI? If that's the case, that seems to be a significant omission.

iOS: List selection is reset to nil when app is sent to background
For some reason, a List will reset its selection to nil when the app is in the background. Steps to reproduce the issue: Run attached sample project Once the app has launched, select a name in the sidebar Move the app to the background Wait a few seconds Bring back the app to the foreground Expected result: The list selection should still be valid Actual result: The list selection is set to nil Notes: I’m using a StateObject, which should be the way to ensure that data isn’t regenerated when views are rendered. Is this a bug or something else needs to be taken care of? class AppModel: ObservableObject {     @Published var selectedPerson: Person? } @main struct NilListSelectionApp: App {     @StateObject var appModel = AppModel()     var body: some Scene {         WindowGroup {             ContentView()                 .environmentObject(appModel)         }     } } struct Person: Identifiable, Hashable {     let id: UUID     let firstname: String     init(firstname: String) {         id = UUID()         self.firstname = firstname     } } struct ContentView: View {     @EnvironmentObject private var appModel: AppModel     var body: some View {         NavigationSplitView {             SidebarView()         } detail: {             PersonView(person: appModel.selectedPerson)         }     } } struct SidebarView: View {     @EnvironmentObject private var appModel: AppModel     private let persons = [Person(firstname: "Joe"), Person(firstname: "Jane")]     var body: some View {         List(persons, id:\.self, selection: $appModel.selectedPerson) { person in             Text(person.firstname).tag(person)         }         .listStyle(.sidebar)     } } struct PersonView: View {     let person: Person?     var body: some View {         if let person {             Text(person.firstname)         }         else {             Text("No Selection")         }     } }

iOS 17b6: Simultaneous accesses to ..., but modification requires exclusive access crash using Observation and SwiftUI
Since iOS/iPadOS beta 6, I get a crash just by simply selecting an item in the sidebar of a navigation view. The selected item is part of an app mode, with conforms to the Observation protocol: import SwiftUI import Observation @main struct MREAApp: App { @State private var appModel = AppModel.shared var body: some Scene { WindowGroup { ContentView() .environment(appModel) } } } @Observable class AppModel { static var shared = AppModel() var selectedFolder: Folder? = nil } struct Folder: Hashable, Identifiable { let id = UUID() let name: String } struct ContentView: View { @Environment(AppModel.self) private var appModel var folders = [Folder(name: "Recents"), Folder(name: "Deleted"), Folder(name: "Custom")] var body: some View { NavigationSplitView { SidebarView(appModel: appModel, folders: folders) } detail: { if let folder = appModel.selectedFolder { Text(folder.name) } else { Text("No selection") } } } } struct SidebarView: View { @Bindable var appModel: AppModel var folders: [Folder] var body: some View { List(selection: $appModel.selectedFolder) { ForEach(folders, id: \.self) { folder in NavigationLink(value: folder) { Text(folder.name) } } } } } To reproduce the bug, just tap on one of the item. Oddly enough, this works fine in the Simulator. macOS 14 beta 5 is not affected either. Apple folks: FB12981860

Unable to export Strings Catalog
I've spent 3 days moving localization from my older project to my new project and converted to Strings Catalog. When I tried to export, I got the Unable to build project for localization string extraction error. Read about that and the workaround seems to be to set Localisation Export Supported to NO, which I did. I worked once and now it refuses to export and complains about missing targets, which I had to remove from the export process as recommended. WTH? Or, at some point it complained about a missing Swift Package. wwdc2023-10155

manageSubscriptionsSheet not showing
Trying to debug StoreKit on device using a sandboxed user. When I want to show manageSubscriptionsSheet, the screen flashes but nothing shows. This is visible in the console: SKEngagementRemoteViewTask: Presenting system engagement request. Request: {length = 5347, bytes = 0x62706c69 73743030 d4010203 04050607 ... 00000000 000012d7 } Present engagement request: {length = 5347, bytes = 0x62706c69 73743030 d4010203 04050607 ... 00000000 000012d7 }, clientBundleID: com.acme.myapp Finished presenting engagement request with view service There isn't much information in the documentation so I'm not sure if it's me not doing things correctly or a bug in iOS 17.2?

Is StoreKit.Transaction.currentEntitlements down at the moment?
Calling StoreKit.Transaction.currentEntitlements today just doesn't return. It just sits there. for await result in StoreKit.Transaction.currentEntitlements { switch result { case .verified(let transaction): currentTransaction = transaction case .unverified(let transaction, let error): currentTransaction = transaction } } The for loop never starts. This is using a Sandboxed user that made a renewal subscription purchase. Everything was working fine yesterday. Nothing on my end has changed since then. Is something wrong with StoreKit?

Context menus, alerts, popovers and tips do not respect preferred color scheme
It seems like some UI elements just don't use the preferred color scheme of their parent element: import SwiftUI struct ContentView: View { var body: some View { VStack { Button("Hold Me") { } .contextMenu(ContextMenu(menuItems: { Button("I should be dark") { } })) } .padding() .preferredColorScheme(.dark) } } If you set the device appearance to dark, then the context menu shows the correct color scheme. Setting .preferredColorScheme(.dark) to Button directly doesn't help. Aside from context menus, this applies to all sorts of elements: popovers, alerts, tips, ... Is there a workaround for this?
