Share sheet configuration
I'm trying to configure the share sheet. My project uses techniques from the Apple Sample project called CoreDataCloudKitShare which is found here: https://developer.apple.com/documentation/coredata/sharing_core_data_objects_between_icloud_users# In this sample code there's a "PersistenceController" which is an NSPersistentCloudKitContainer. In the "PersistenceController+SharingUtilities" file there are some extensions, and one of them is this: func configure(share: CKShare, with photo: Photo? = nil) { share[CKShare.SystemFieldKey.title] = "A cool photo" } This text "A cool photo" seems to be the only bespoke configuration of the share sheet within this project. I want to have more options to control the share sheet, does anyone know how this might be achieved? Thank you!

In SwiftUI in iOS 18.1, `SectionedFetchRequest` is not refreshed when changes are done to the fetched entity's attributes.
Hi, This issue started with iOS 18, in iOS 17 it worked correctly. I think there was a change in SectionedFetchRequest so maybe I missed it but it did work in iOS 17. I have a List that uses SectionedFetchRequest to show entries from CoreData. The setup is like this: struct ManageBooksView: View { @SectionedFetchRequest<Int16, MyBooks>( sectionIdentifier: \.groupType, sortDescriptors: [SortDescriptor(\.groupType), SortDescriptor(\.name)] ) private var books: SectionedFetchResults<Int16, MyBooks> var body: some View { NavigationStack { List { ForEach(books) { section in Section(header: Text(section.id)) { ForEach(section) { book in NavigationLink { EditView(book: book) } label: { Text(book.name) } } } } } .listStyle(.insetGrouped) } } } struct EditView: View { private var book: MyBooks init(book: MyBooks) { print("Init hit") self.book = book } } Test 1: So now when I change name of the Book entity inside the EditView and do save on the view context and go back, the custom EditView is correctly hit again. Test 2: If I do the same changes on a different attribute of the Book entity the custom init of EditView is not hit and it is stuck with the initial result from SectionedFetchResults. I also noticed that if I remove SortDescriptor(\.name) from the sortDescriptors and do Test 1, it not longer works even for name, so it looks like the only "observed" change is on the attributes inside sortDescriptors. Any suggestions will be helpful, thank you.

AVSpeechUtterance problem
I see this error in the debugger: #FactoryInstall Unable to query results, error: 5 IPCAUClient.cpp:129 IPCAUClient: bundle display name is nil Error in destroying pipe Error Domain=NSCocoaErrorDomain Code=4099 "The connection from pid 5476 on anonymousListener or serviceListener was invalidated from this process." UserInfo={NSDebugDescription=The connection from pid 5476 on anonymousListener or serviceListener was invalidated from this process.} on this function: func speakItem() { let utterance = AVSpeechUtterance(string: item.toString()) utterance.voice = AVSpeechSynthesisVoice(language: "en-GB") try? AVAudioSession.sharedInstance().setCategory(.playback) utterance.rate = 0.3 let synthesizer = AVSpeechSynthesizer() synthesizer.speak(utterance) } When running without the debugger, it will (usually) speak once, then it won't speak unless I tap the button that calls this function many times. I know AVSpeech has problems that Apple is long aware of, but I'm wondering if anyone has a work around. I was thinking there might be a way to call the destructor for AVSpeechUtterance and generate a new object each time speech is needed, but utterance.deinit() shows: "Deinitializers cannot be accessed"

What's the best way to support Genmoji with SwiftUI?
I want to support Genmoji input in my SwiftUI TextField or TextEditor, but looking around, it seems there's no SwiftUI only way to do it? If none, it's kind of disappointing that they're saying SwiftUI is the path forward, but not updating it with support for new technologies. Going back, does this mean we can only support Genmoji through UITextField and UIViewRepresentable? or there more direct options? Btw, I'm also using SwiftData for storage.

SwiftData: Default value for added property
Let's say I have a model like this: @Model final class DataModel { var firstProperty: String = "" } Later on I create a new property as such: @Model final class DataModel { enum DataEnum { case dataCase } var firstProperty: String = "" var secondProperty: DataEnum? = .dataCase } My expectation is for the data that is already stored, the secondProperty would be added with a default value of .dataCase. However, it's being set to nil instead. I could have sworn it would set to the default value given to it. Has that changed, or has it always been this way? Does this require a migration plan?

SwiftUI DatePicker size not configurable
Hey guys, I'm totally new to Swift programming and I'm setting up a view for registering users. I use a VStack to organize the TextFields as well as a DatePicker, but the last one seems to be very rebellious. Here's my code: VStack { TextField("E-Mailadresse", text: $mail) .frame(height: 30) .textFieldStyle(.roundedBorder) .multilineTextAlignment(.center) .focused($hasFocus, equals: .mail) .onKeyPress(.tab, action: {hasFocus = .password; return .handled}) SecureField("Passwort", text: $password) .frame(height: 30) .textFieldStyle(.roundedBorder) .multilineTextAlignment(.center) .focused($hasFocus, equals: .password) .onKeyPress(.tab, action: {hasFocus = .name; return .handled}) TextField("Name", text: $name) .frame(height: 30) .textFieldStyle(.roundedBorder) .multilineTextAlignment(.center) .focused($hasFocus, equals: .name) .onKeyPress(.tab, action: {hasFocus = .prename; return .handled}) TextField("Vorname", text: $prename) .frame(height: 30) .textFieldStyle(.roundedBorder) .multilineTextAlignment(.center) .focused($hasFocus, equals: .prename) .onKeyPress(.tab, action: {hasFocus = .birthday; return .handled}) DatePicker("Geb.:", selection: $birthday, displayedComponents: [.date]) .datePickerStyle(.wheel) .clipped() //.focused($hasFocus, equals: .birthday) Button("Registrieren") {self.register()} .padding(.top, 20) .keyboardShortcut(.defaultAction) } .frame(width: 375) } And this is how it looks like: As you can see, neither is the DatePicker centered correctly (it's more left located) nor is it clipped (reduced). I also tried adding a .frame() to itself, then I was ably to reduce it to the preferred height, but I can' reduce its width and as a result of this, I can also not write a full label like "Date of Birth" or something, because the wheel of the DatePicker always overlays it... Is that a kind of misbehavior or am I missing something? Thank you very much in anticipation for your feedback! Kind regards Kevin

Management of multiple root views in SwiftUI
Hey guys, I'm totally unexperienced in Swift coding and I'm doing my first steps using Swift Playgrounds on my macOS as well as on my iPadOS. I'm setting up a simple App that can be divided in 4 main categories (Splash, Authentication, Content, Setup). Each category (except the Splash as the short intro when running the app) can have a NavigationStack (e. g. switching between login view, register view, forgott password view in authentication). So I thought about having a root view for each of them. My google research gave me lots of ways and hints but it's not clear at all for me if I should and how I should do this. I often read about a RootViewController but I guess that's UIKit stuff and nothing for SwiftUI. Then I read about delegates and such. Then, I read an article that exactly fits my goals and I just liked to get your opinion what you think about this way to solve my plan: First of all, I define a separate class for a appRootManager: final class appRootManager: ObservableObject { enum eRootViews { case Splash, Authentification, Content, Setup } @Published var currentRoot: eRootViews = .Splash } The main app file looks like this: @main struct MyApp: App { @StateObject private var oRootManager = appRootManager() var body: some Scene { WindowGroup() { Group { switch oRootManager.currentRoot { case .Splash: viewSplash() case .Authentification: viewLogin() case .Content: viewContent() case .Setup: viewSetup() } } .environmentObject(oRootManager) .modelContainer(for: [Account.self]) } } } In each of the for root view files (e. g. Splash view) I make the appRootManager addressable and switch the root view by updating the enum value, like for example: struct viewSplash: View { @EnvironmentObject private var oRootManager: appRootManager var body: some View { ZStack { Color.blue .ignoresSafeArea() Text("Hello World") .font(.title) .fontWeight(.semibold) .foregroundColor(.white) } .onAppear() { DispatchQueue.main.asyncAfter(deadline: .now() + 3) { withAnimation(.spring()) {oRootManager.currentRoot = .Authentification} } } } } It works fine and does exactly what I like to have (when I run the app out of Swift Playgrounds). I'm just wondering why it does not work in the App Preview in Swift Playgrounds and this is why I'd like to have your opinion to the way I solve my plan. I'm very happy for any feedback. Thanks a lot in anticipation! Kind regards Kevin

Problem with audio files in Swift
Hi guys, I've been this app for quite a while and I wanted to add audio to it but I've encountered a strange bug. Whenever I try to play the audio from the testing device, it prints out that the audio file cannot be found. I've checked multiple times the names and the code and I get no errors there whatsoever. I have no idea what might be causing this. Here's a part of the code: `import SwiftUI import AVFoundation struct Card: Identifiable { let id = UUID() let heading: String let description: String let imageName: String let detailDescription: String let sonification: String } struct ExplorepageUI: View { @State private var selectedCard: Card? @State private var showMore = false @State private var currentIndex = 0 @State private var currentCards: [Card] = [] let galaxies = [ Card(heading: "The Mice Galaxies", description: "They’re located about 300 million light-years away in the constellation Coma Berenices.", imageName: "TheMiceGalaxiesHubble", detailDescription:""" Their name refers to the long tails produced by tidal action, the relative difference between gravitational pulls on the near and far parts of each galaxy, known here as a galactic tide. It is a possibility that both galaxies, which are members of the Coma Cluster, have experienced collision, and will continue colliding until they coalesce. The colors of the galaxies are peculiar. In NGC 4676A a core with some dark markings is surrounded by a bluish white remnant of spiral arms. The tail is unusual, starting out blue and terminating in a more yellowish color, despite the fact that the beginning of each arm in virtually every spiral galaxy starts yellow and terminates in a bluish color. NGC 4676B has a yellowish core and two arcs; arm remnants underneath are bluish as well. The galaxies were photographed in 2002 by the Hubble Space Telescope. In the background of the Mice Galaxies, there are over 3000 galaxies, at distances up to 13 billion light-years. """, sonification: "SonificationoftheMiceGalaxies"), `class MusicPlayer: ObservableObject { private var audioPlayer: AVPlayer? func playSound(named sonificationFileName: String){ if let url = Bundle.main.url(forResource: sonificationFileName, withExtension: "mp3"){ print("✅ Found audio file at: \(url)") audioPlayer = try? AVPlayer(url: url) audioPlayer?.play() print("🎵 Audio should now be playing!") } else { print("❌ Audio file not found: \(sonificationFileName).mp3") } } func pause(){ audioPlayer?.pause() } }

onMove bug
I'm not sure where to report this, so here it is. If you have a list of items and you make them clickable and movable, moving one or more items in the list and then clicking will cause them to move. This is yet another reason that SwiftData needs to track onMove. Minimal reproducible code: // // ContentView.swift // exampleBug // // Create a new project. // Replace the default Item class with the one below, and replace ContentView with its class below // Run the app and add a few items a few seconds apart so you can tell them apart. // Drag an item to a new position in the list. // Click one of the checkboxes and watch the list positions change for no reason! // import SwiftUI import SwiftData @Model final class Item { var timestamp: Date var checkbox: Bool = false init(timestamp: Date) { self.timestamp = timestamp } } struct ContentView: View { @Environment(\.modelContext) private var modelContext @State private var editMode = EditMode.inactive @Query private var items: [Item] var body: some View { NavigationStack { List { ForEach(items) { item in HStack { Text(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard)) Button("", systemImage: item.checkbox ? "checkmark.circle.fill" : "circle") { item.checkbox.toggle() try? modelContext.save() } } } .onMove(perform: { indices, newOffset in var theItems = items theItems.move(fromOffsets: indices, toOffset: newOffset) }) } .environment(\.editMode, $editMode) .moveDisabled(false) .toolbar { ToolbarItem(placement: .navigationBarTrailing) { EditButton() } ToolbarItem { Button(action: addItem) { Label("Add Item", systemImage: "plus") } } } } } func addItem() { withAnimation { let newItem = Item(timestamp: Date()) modelContext.insert(newItem) } } func deleteItems(offsets: IndexSet) { withAnimation { for index in offsets { modelContext.delete(items[index]) } } } } #Preview { ContentView() .modelContainer(for: Item.self, inMemory: true) } code-block

SwiftUI TextSelection crash on macOS
I have a very simple SwiftUI app, works fine on iOS, crashes on macOS: struct ContentView: View { @State var testStr: String = "" @State var selection: TextSelection? = nil var body: some View { VStack { TextField("Test", text: $testStr, selection: $selection) .onChange(of: selection) {print("selection changed")} } .padding() } } • Start app, write something in the TextField and move the cursor around. iOS: "selection changed" Mac: nothing (Bug ?) • double click on some word both Mac and iOS: "selection changed" • write some more in the TextField iOS: selection changed Mac: crash Any idea what I am doing wrong?

SwiftUI/WebKit Allowing popups and links
We are using an imbedded WKWebView in a SwiftUI view. There are links within the pages being viewed - they are company pages - and some link to other pages as well as open named (or unnamed) browser tabs. In our implementation, when there is a named (or unnamed) link to another browser tab, the view does not do anything. Any ideas on how to allow tabs to open in some manner and allow the users to access the links?

Drag and drop from the Files app onto a List doesn't work anymore in iOS 18
Hi I think I found an issue with SwiftUI List on iOS 18.0 and 18.1 Using the ContentView from the code block below: if you try to drag and drop the globe image onto the blue rows, things work fine on both iOS 17 and 18 with either List or VStack. However if you first drag and drop the image onto the Files app and then drag the newly created PNG file back into our app, it won't work on iOS 18 with the blue row inside the List. Also there's no visual feedback when hovering that blue row (unlike the one inside the VStack). I've tried various view modifiers but no luck so far. Any help is appreciated. Thank you. FB15618535 struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .resizable() .scaledToFit() .frame(height: 100) .draggable(Image(systemName: "globe")) List { Color.gray .frame(height: 100) Color.blue .frame(height: 100) .dropDestination(for: Image.self) { _, _ in print("List dropped") return true } } VStack { Color.gray Color.blue .dropDestination(for: Image.self) { _, _ in print("VStack dropped") return true } } } .padding() } }

SwiftUI Color Issue
I have ran into an issue that is illustrated by the code in the following GitHub repository. https://github.com/dougholland/ColorTest When a SwiftUI color originates from the ColorPicker it can be persisted correctly and renders the same as the original color. When the color originates from the MapFeature.backgroundColor, it is always rendered with the light appearance version of the color and not the dark appearance version. The readme in the GitHub repo has screenshots that show this. Any assistance would be greatly appreciated as this is affecting an app that is in development and I'd like to resolve this before the app is released. If this is caused by a framework bug, any possible workaround would be greatly appreciated also. I suspect it maybe a framework issue, possibly with some code related to the MapFeature.backgroundColor, because the issue does not occur when the color originates from the ColorPicker.
