We ran into a bug with our app Bezel (https://getbezel.app). When running on macOS Tahoe, windows would get partially clipped. This is because we have SwiftUI views that are larger than the window size, our SwiftUI views are supposed to be centered, which they are on macOS 13, 14, 15. But on macOS 26 (beta 1), the window contents are top-left aligned. This seems to be a bug, I have submitted FB18201269. This is my code: WindowGroup { ZStack { Color.green ZStack { Color.yellow Text("Hi") } .aspectRatio(1, contentMode: .fill) .border(.red) } } This first screenshot shows the old behavior on macOS 15: This second screenshot shows the new behavior on macOS 26 (beta 1) Can anyone confirm if this is indeed a bug, or if this an intended change in behavior?

Previously, I sorted my FetchResult in a TableView like this: @FetchRequest( sortDescriptors: [SortDescriptor(\.rechnungsDatum, order: .forward)], predicate: NSPredicate(format: "betragEingang == nil OR betragEingang == 0") ) private var verguetungsantraege: FetchedResults<VerguetungsAntraege> ... body ... Table(of:VerguetungsAntraege.self, sortOrder: $verguetungsantraege.sortDescriptors) { TableColumn("date", value:\.rechnungsDatum) { item in Text(Formatters.dateFormatter.string(from: item.rechnungsDatum ?? Date()) ) } .width(120) TableColumn("rechNrKurz", value:\.rechnungsNummer) { item in Text(item.rechnungsNummer ?? "") } .width(120) TableColumn("betrag", value:\.totalSum ) { Text(Formatters.currencyFormatter.string(from: $0.totalSum as NSNumber) ?? "kein Wert") } .width(120) TableColumn("klient") { Text(db.getKlientNameByUUID(id: $0.klient ?? UUID(), moc: moc)) } } rows: { ForEach(Array(verguetungsantraege)) { antrag in TableRow(antrag) } } There seem to be changes here in Xcode 26. In any case, I always get the error message in each line with TableColumn("title", value: \.sortingField) Ambiguous use of 'init(_:value:content:)' Does anyone have any idea what's changed? Unfortunately, the documentation doesn't provide any information.

How can I create a view that is like the one in the Photos app where you can select an item and it fills the window, then you can drag / swipe between items in that view? I have a working prototype, and it works for photos. But once I get to a video, the gesture no longer works.

I have an app in which the data model is @Observable, and views see it through @Environment(dataModel.self) private var dataModel. Since there are a large number of views, only some of which may need to be redrawn at a given time, I believe that @Observable is more efficient at run time than @Published and @ObservedObject I’ve been trying to make the app document based. Although I started using SwiftData, it has trouble with Codable, and a long thread in the Developer forum suggests that SwiftData does not support the Undo manager - and in any event, simple JSON serialization is all that this app requires. Unfortunately, ReferenceFileDocument inherits from ObservableObject, which seems to not play nice with @Observable. I’d like to keep using @Observable, but haven’t been able to figure out how. When I deserialize a JSON ReferenceFileDocument, I can’t seem to connect it to an @Observable class instance and to let the various views and view models know where to find and update it. I’d appreciate advice on how to implement document persistence in this app. Also, the default behaviour of DoumentGroup provides a nice menu to, another things, rename a new file to something other than Untitled xx, but it doesn’t appear to work (there is an extensive thread on the Developer website discussing this issue). Is there a solution to this problem? Thanks for any help you can offer.

I am looking at the demo code for CarPlay Maps app - https://developer.apple.com/documentation/carplay/integrating-carplay-with-your-navigation-app This worked in IOS 18 but now on IOS26 it doesn't work, eg the map in the CarPlay app no longer shows up. I don't see any docks to say what has changed, I wonder if anyone has any ideas?

Hello I'm currently building a feature within an ios app using SwiftUI and Mapkit to record the gps cordinates of a user as they move and render the track on the map. the idea is not really to have a "track" but to have a visual representation of the area the user sees while they are moving around. I need this width/breadth to be relative to the map and not the screen, such that when I zoom in and out of the map, the size will adjust automatically.

The URL directory obtained by UIDocumentPickerVieweController can be read and written in the directory after calling startAccessingDecurityScopeResource. However, after restarting the app, if the URL saved in the package is called startAccessingDecurityScopeResource again and returns NO, UIDocumentPickerVieweController must be called again to retrieve the URL, and then startAccessingDecurityScopeResource must be called again before continuing the operation. This is too troublesome. Is there a way to continue reading and writing operations in the URL directory after restarting the app?

My app is designed to share and import images with apps such as the File app. I created a program after looking at various information, but the app from which the images are shared does not work, and the screen cannot be moved to the main screen of my app. The program is as follows. How should I modify it? import UIKit import MobileCoreServices import UniformTypeIdentifiers class ShareViewController: UIViewController { let suiteName: String = "group.com.valida.pettyGeneral" let keyString: String = "share-general" override func viewDidLoad() { var nameArray: [String] = [String]() let sharedDefaults: UserDefaults = UserDefaults(suiteName: self.suiteName)! guard let inputItem = self.extensionContext?.inputItems.first as? NSExtensionItem, let attachments = inputItem.attachments else { return } let identifier = UTType.image.identifier let imgAttachments = attachments.filter { $0.hasItemConformingToTypeIdentifier(identifier) } let dispatchGroup = DispatchGroup() for (no, itemProvider) in imgAttachments.enumerated() { dispatchGroup.enter() itemProvider.loadItem(forTypeIdentifier: identifier, options: nil) { [self] item, error in do { if let error = error { throw error } else if let url = item as? URL { let data = try Data(contentsOf: url) let fileManager = FileManager.default let url = fileManager.containerURL(forSecurityApplicationGroupIdentifier: suiteName) if let url = url?.appendingPathComponent(String(no)) { try! data.write(to: url) } nameArray.append(String(no)) } do { dispatchGroup.leave() } } catch { print("Error") do { dispatchGroup.leave() } } } } dispatchGroup.notify(queue: .main) { [self] in // 全ての画像を保存 sharedDefaults.set(nameArray, forKey: self.keyString) sharedDefaults.synchronize() // メニュー画面に移動する openUrl(url: URL(string: "container-general://")) self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil) } } //#selector(openURL(_:))はこの関数がないと作れない @objc func open(_ url: URL) {} func openUrl(url: URL?) { let selector = #selector(open(_ : )) var responder = (self as UIResponder).next while let r = responder, !r.responds(to: selector) { responder = r.next } _ = responder?.perform(selector, with: url) } func openContainerApp() { let url = URL(string: "container-general://") // カスタムスキームを作って指定する var responder: UIResponder? = self while responder != nil { if let application = responder as? UIApplication { let selector = sel_registerName("openURL:") application.perform(selector, with: url) break } responder = responder?.next } } }

In iPadOS 26, the Control Center includes a Multitasking button that lets users switch between full-screen and windowed apps. Is any UISceneDelegate method invoked when this happens, or is there another mechanism by which the app is notified?

I’m trying to add a TextField to the toolbar using .principal placement, and I want it to either fill the screen width or expand based on the surrounding content. However, it’s not resizing as expected — the TextField only resizes correctly when I provide a hardcoded width value. This behavior was working fine in previous versions of Xcode, but seems to be broken in Xcode 26. Not sure if this is an intentional change or a bug. i am using iOS26 beta and Xcode 26 beta struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() .toolbar { ToolbarItem(placement: .principal) { HStack { TextField("Search", text: .constant("")) .textFieldStyle(.roundedBorder) .frame(maxWidth: .infinity) // .frame(width: 300) Button("cancel") { } } .frame(maxWidth: .infinity) } } } } #Preview { NavigationView { ContentView() } }

I’m updating my app’s alternate icons using UIApplication.shared.setAlternateIconName, and I noticed that in iOS 26, Xcode now supports the new .icon file format for App Icons. Is it possible to reference .icon files directly for alternate icons? Or does setAlternateIconName still only support traditional .png assets inside the AppIcon set? I couldn’t find any documentation confirming this either way, and I want to ensure compatibility with the new format while supporting alternate icons. Any clarification or Apple documentation link would be greatly appreciated!

1.When I attempted to open the subsequent AppIntent within the perform method of the AppIntent instance, I always received the following error： How to solve the problems of inconsistency of this type? I couldn't find any sample code. 2.When I used method 'Button(intent: OpenAppIntent())' to open my app through the dialog custom view of AppIntent, but I couldn't find a way to close this AppIntent dialog. How can i remove this dialog?

error I get when I try and install predictive code completion model

I am trying out the new AttributedString binding with SwiftUI’s TextEditor in iOS26. I need to save this to a Core Data database. Core Data has no AttributedString type, so I set the type of the field to “Transformable”, give it a custom class of NSAttributedString, and set the transformer to NSSecureUnarchiveFromData When I try to save, I first convert the Swift AttributedString to NSAttributedString, and then save the context. Unfortunately I get this error when saving the context, and the save isn't persisted: CoreData: error: SQLCore dispatchRequest: exception handling request: <NSSQLSaveChangesRequestContext: 0x600003721140> , <shared NSSecureUnarchiveFromData transformer> threw while encoding a value. with userInfo of (null) Here's the code that tries to save the attributed string: struct AttributedDetailView: View { @ObservedObject var item: Item @State private var notesText = AttributedString() var body: some View { VStack { TextEditor(text: $notesText) .padding() .onChange(of: notesText) { item.attributedString = NSAttributedString(notesText) } } .onAppear { if let nsattributed = item.attributedString { notesText = AttributedString(nsattributed) } else { notesText = "" } } .task { item.attributedString = NSAttributedString(notesText) do { try item.managedObjectContext?.save() } catch { print("core data save error = \(error)") } } } }

Hi all, I’m trying to implement a collapsible section in a List on watchOS (watchOS 10+). The goal is to have a disclosure chevron that toggles a section open/closed with animation, similar to DisclosureGroup on iOS. Unfortunately, DisclosureGroup is not available on watchOS. 😢 On iOS, this works as expected using this Section init: Section("My Header", isExpanded: $isExpanded) { // content } That gives me a tappable header with a disclosure indicator and the animation built in, as expected. But on watchOS, this same init displays the header, but it’s not tappable, and no disclosure triangle appears. I’ve found that to get it working on watchOS, I need to use the other initializer: Section(isExpanded: $isExpanded) { // content } header: { Button(action: { isExpanded.toggle() }) { HStack { Title("My Header") Spacer() Image(systemName: isExpanded ? "chevron.down" : "chevron.right") } } That works, but feels like a workaround. Is this the intended approach for watchOS, or am I missing a more native way to do this? Any best practices or alternative recommendations appreciated. Thanks!

When the perform method of my AppIntent returns the custom view's dialog, and after I click the "Click Test" button, my app will be launched, but this dialog does not close. How can I close it? struct QuestionResultView: View { var body: some View { VStack { if #available(iOS 17.0, *) { Button(role:.cancel, intent: OpenAppIntent()) { Text("Click Test") } } }.frame(height: 300) } } struct OpenAppIntent : AppIntent { static let title: LocalizedStringResource = "Open my app" static let openAppWhenRun: Bool = true static let isDiscoverable: Bool = false; @MainActor func perform() async throws -> some IntentResult { return .result() } } struct OpenPhotoRecognizing: AppIntent { static let title: LocalizedStringResource = "Read photo" static let description = IntentDescription("") static let openAppWhenRun: Bool = false func perform() async throws -> some IntentResult & ShowsSnippetView & ProvidesDialog{ return .result(dialog: "Demo Test") { DemoResultView() } } }

The default behavior on UIScrollView is that "canCancelContentTouches" is true. If you add a UIButton to a UICollectionViewCell and then scroll (drag) the scroll view with a touch beginning on that button in that cell, it cancels ".touchUpInside" on the UIButton. However, if you have a Button in a SwiftUI view configured with "contentConfiguration" it does not cancel the touch, and the button's action is triggered if the user is still touching that cell when the scroll (drag) completes. Is there a way to forward the touch cancellations to the SwiftUI view, or is it expected that all interactivity is handled only in UIKit, and not inside of "contentConfiguration" in specific cases? This behavior seems to occur on all SwiftUI versions supporting UIHostingConfiguration so far.

My Objective-C Catalyst app when built with Xcode 16.x/iOS 18 does not have a visible Tab Bar when run on Sequoia. App starts up in first tab, but there is no way to access other tabs. The same app when run on macOS Sonoma (or macOS Catalina) has a normal Tab Bar. The app has an initial View UITabBarController with 3 tabs. The main tab is a UiSplitViewController. Minimum macOS deployment 10.5. If app is built on Sonoma with Xcode 15.x/iOS 17 the Tab Bar is normal on macOS Sonoma, Sequoia, and Catalina. I've tried without success: if (@available(macCatalyst 18.0, *)) { self.tabBarController.tabBarHidden = false; } else { // Fallback on earlier versions } I wonder if this console log message has anything to do with the problem: CLIENT OF UIKIT REQUIRES UPDATE: This process does not adopt UIScene lifecycle. This will become an assert in a future version.

I was trying to adapt memoji in my app which write by objective-c.I have a textView for user input and I need to keep allowsEditingTextAttributes == NO for some reason.Is there any other way to show memoji sticker in system emoji keyboard?Thanks!

Sorry if this is too basic, but I really can't figure out how to make this work. I am trying to make a journal app and I want to have a button that creates a new journalentry and then loads it. This code snippet (I removed irrelevant bits) shows how I'm trying to go about it. Basically, the newEntryButtons should launch a JournalPromptRoute for one of the different options: that's the method argument. But putting .createNewEntry() inside the argument means that new entries are being constantly created. I want the system to create a new entry once on the button press and then go to it from the navigationDestination area. Can anyone please explain to me how this is supposed to work? I believe the code snippet is detailed enough to get the point across but please let me know if you need more info. case library case blank(entry: Entry) case mystery case summary(entry: Entry) case entry(entry: Entry) } struct JournalHome: View { @ObservedObject var viewModel: JournalViewModel var mainContent: some View { ScrollView { newEntryButtons LazyVStack { ForEach(filteredEntries) { entry in NavigationLink( value: JournalPromptRoute.entry(entry: entry) ) { JournalCard(entry) } } } } } var body: some View { NavigationStack(path: $path) { mainContent .navigationDestination(for: JournalPromptRoute.self) { route in switch route { case .blank(let entry): JournalEntryView( entry: entry, index: 0, viewModel: viewModel ) } } } } var newEntryButtons: some View { ScrollView(.horizontal) { HStack(spacing: 15) { EntryButton( description: "Add blank entry", method: JournalPromptRoute.blank(entry: viewModel.createNewEntry()), viewModel: viewModel, path: $path ) EntryButton( description: "Select a Journey", method: JournalPromptRoute.library, viewModel: viewModel, path: $path ) EntryButton( description: "Let the Journey find you", method: JournalPromptRoute.mystery, viewModel: viewModel, path: $path ) } } } }
