I have an app with two file types with the following extensions: gop (an exported type), sgf (an imported type). The Save command fails after the following sequence of events: I open a gop file, say the file "A.gop". I save this file as an sgf file, say "A.sgf". This Save As works perfectly and the document name in the document’s title bar has changed to "A.sgf". I change something in the document and then try to Save this change. This should just resave the document to "A.sgf", but "A.sgf" remains untouched. Instead I get a system alert with the message The document “A.sgf” could not be saved. A file with the name “A.gop” already exists. To save the file, either provide a different name, or move aside or delete the existing file, and try again. In the Xcode console I get the following diagnostic: NSFileSandboxingRequestRelatedItemExtension: an error was received from pboxd instead of a token. Domain: NSPOSIXErrorDomain, code: 2 [NSFileCoordinator itemAtURL:willMoveToURL:] could not get a sandbox extension. oldURL: file:///Users/francois/Desktop/A.sgf, newURL: file:///Users/francois/Desktop/A.gop The problem seems to relate to the sandbox. But I am at a loss to find a solution. (After closing the alert, I check that A.sgf did not register the change.) If I open an sgf file, say "B.sgf", save it as "B.gop", make a change in the document and then try to save this change (into "B.gop"), I hit the same problem, with "gop" and "sgf" interchanged. If, instead of saving "A.gop" as "A.sgf", I save it as "B.sgf", make a change in the document and then try to save this change into "B.sgf", I get the following system alert: The document “B.sgf” could not be saved. You don’t have permission. To view or change permissions, select the item in the Finder and choose File > Get Info. And in the Xcode console I get the following diagnostic: NSFileSandboxingRequestRelatedItemExtension: an error was received from pboxd instead of a token. Domain: NSPOSIXErrorDomain, code: 2 [NSFileCoordinator itemAtURL:willMoveToURL:] could not get a sandbox extension. oldURL: file:///Users/francois/Desktop/B.sgf, newURL: file:///Users/francois/Desktop/B.gop Again the sandbox ! (After closing the alert, I check that B.sgf did not register the change.) It’s clear my code is missing something, but what?

In keyboard shortcuts this buttons at the bottom are overlappin. Any one else?

I want to record screen ,and than when I call the method stopCaptureWithHandler:(nullable void (^)(NSError *_Nullable error))handler to stop recording and saving file. before call it,I check the value record of RPScreenRecorder sharedRecorder ,the value is false , It's weird! The screen is currently being recorded ! I wonder if the value of [RPScreenRecorder sharedRecorder].record will affect the method stopCaptureWithHandler: -(void)startCaptureScreen { [[RPScreenRecorder sharedRecorder] startCaptureWithHandler:^(CMSampleBufferRef _Nonnull sampleBuffer, RPSampleBufferType bufferType, NSError * _Nullable error) { //code } completionHandler:^(NSError * _Nullable error) { //code }]; } - (void)stopRecordingHandler { if([[RPScreenRecorder sharedRecorder] isRecording]){ // deal error .sometime isRecording is false }else { [[RPScreenRecorder sharedRecorder] stopCaptureWithHandler:^(NSError * _Nullable error) { }]; } } here are my code.

In iOS 18, I've observed unexpected behavior related to the UINavigationBar when transitioning between view controllers that have differing navigation bar visibility settings. Specifically, when returning from a modal presentation or a web view, the navigation bar reappears with an unexpected height (e.g., 103 points) and lacks content, displaying only an empty bar. Start with a UIViewController (e.g., HomeViewController) where the navigation bar is hidden using: override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) navigationController?.setNavigationBarHidden(true, animated: animated) } Present another UIViewController (e.g., a web view) modally. Dismiss the presented view controller. Observe that upon returning to HomeViewController, the navigation bar is visible with increased height and lacks expected content. Expected Behavior: The navigation bar should remain hidden upon returning to HomeViewController, maintaining the state it had prior to presenting the modal view controller. Actual Behavior: Upon dismissing the modal view controller, the navigation bar becomes visible with an unexpected height and lacks content, leading to a disrupted user interface. Additional Observations: This issue is specific to iOS 18; it does not occur in iOS 17 or earlier versions. The problem seems to stem from setting the navigation bar to be visible in the viewWillDisappear method, as shown below: override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) navigationController?.setNavigationBarHidden(false, animated: animated) } Removing or modifying this line mitigates the issue, suggesting a change in the view controller lifecycle behavior in iOS 18. Request for Clarification: Is this change in behavior intentional in iOS 18, or is it a regression? Understanding whether this is a new standard or a bug will help in implementing appropriate solutions. Workaround: As a temporary measure, I've adjusted the navigation bar visibility settings to avoid changing its state in viewWillDisappear, instead managing it in viewWillAppear or viewDidAppear.

I’m working with AppIntents and AppEntity to integrate my app’s data model into Shortcuts and Siri. In the example below, I define a custom FoodEntity and use it as a @Parameter in an AppIntent. I’m providing dynamic options for this parameter via an optionsProvider. In the Shortcuts app, everything works as expected: when the user runs the shortcut, they get a list of food options (from the dynamic provider) to select from. However, in Siri, the experience is different. Instead of showing the list of options, Siri asks the user to say the name of the food, and then tries to match it using EntityStringQuery. I originally assumed this might be a design decision to allow hands-free use with voice, but I found that if you use an AppEnum instead, Siri does present a tappable list of options. So now I’m wondering: why the difference? Is there a way to get the @Parameter with AppEntity + optionsProvider to show a tappable list in Siri like it does in Shortcuts or with an AppEnum? Any clarification on how EntityQuery.suggestedEntities() and DynamicOptionsProvider interact with Siri would be appreciated! struct CaloriesShortcuts: AppShortcutsProvider { static var appShortcuts: [AppShortcut] { AppShortcut( intent: AddCaloriesInteractive(), phrases: [ "Add to \(.applicationName)" ], shortTitle: "Calories", systemImageName: "fork" ) } } struct AddCaloriesInteractive: AppIntent { static var title: LocalizedStringResource = "Add to calories log" static var description = IntentDescription("Add Calories using Shortcuts.") static var openAppWhenRun: Bool = false static var parameterSummary: some ParameterSummary { Summary("Calorie Entry SUMMARY") } var displayRepresentation: DisplayRepresentation { DisplayRepresentation(stringLiteral:"Add to calorie log") } @Dependency private var persistenceManager: PersistenceManager @Parameter(title: LocalizedStringResource("Food"), optionsProvider: FoodEntityOptions()) var foodEntity: FoodEntity @MainActor func perform() async throws -> some IntentResult & ProvidesDialog { return .result(dialog: .init("Added \(foodEntity.name) to calorie log")) } } struct FoodEntity: AppEntity { static var defaultQuery = FoodEntityQuery() @Property var name: String @Property var calories: Int init(name: String, calories: Int) { self.name = name self.calories = calories } static var typeDisplayRepresentation: TypeDisplayRepresentation { TypeDisplayRepresentation(name: "Calorie Entry") } static var typeDisplayName: LocalizedStringResource = "Calorie Entry" var displayRepresentation: AppIntents.DisplayRepresentation { DisplayRepresentation(title: .init(stringLiteral: name), subtitle: "\(calories)") } var id: String { return name } } struct FoodEntityQuery: EntityQuery { func entities(for identifiers: [FoodEntity.ID]) async throws -> [FoodEntity] { var result = [FoodEntity]() for identifier in identifiers { if let entity = FoodDatabase.allEntities().first(where: { $0.id == identifier }) { result.append(entity) } } return result } func suggestedEntities() async throws -> [FoodEntity] { return FoodDatabase.allEntities() } } extension FoodEntityQuery: EntityStringQuery { func entities(matching string: String) async throws -> [FoodEntity] { return FoodDatabase.allEntities().filter({$0.name.localizedCaseInsensitiveCompare(string) == .orderedSame}) } } struct FoodEntityOptions: DynamicOptionsProvider { func results() async throws -> ItemCollection<FoodEntity> { ItemCollection { ItemSection("Section 1") { for entry in FoodDatabase.allEntities() { entry } } } } } struct FoodDatabase { // Fake data static func allEntities() -> [FoodEntity] { [ FoodEntity(name: "Orange", calories: 2), FoodEntity(name: "Banana", calories: 2) ] } }

Hello, the LocalizedStringKey does not work in the live activity. What do you suggest me to use in order to get localization in the live activity?

I'm trying to create a .pkg installer with productbuild/pkgbuild. But I'd also like to add my custom installer plugin to this. I'm using the following script. I'd like to add my bundle into this script. Since there are no official docs from apple how to do this nor there are a lot of updated resources, here are some things I have tried. adding the following line to Distrubtion.xml <bundle id="pluginid" path="path/to/myplugin.bundle"/> adding component tag to pkgbuild also doesn't do anything --component "path/to/myplugin.bundle" The bundle itself is build with XCode - it is a simple UI for user to type some input in Apple provides documentation for Distribution.xml file, which supports different UI elements but doesn't support text input - docs I have been also looking at this tutorial , it is very outdated but i could still fit it to my needs except the part where the .bundle file needs to be inserted into .pkg. Note - there is no option to view the contents of .pkg file build with pkbuild/productbuild How can i do this process correctly? I would like to link my installer pane plugin to a generic .pkg(with licenses and so on). I'd appreciate any kind of help!

I am experiencing memory leaks in my iOS app that seem to be related to an issue between UIInputView and _UIInputViewContent. After using the memory graph, I'm seeing that instances of these objects aren't being deallocated properly. The UIInputViewController whichs holds the inputView is being deallocated properly along with its subviews.I have tried to remove all of UIInputViewController's subviews and their functions but the uiInputView is not being deallocated. The current setup of my app is a collectionView with multiple cell,each possessing a textfield with holds a UIInputViewController.When i scroll up or down,the views are being reused as expected and the number of UIInputViewController stays consistent with the number of textfields.However the number of inputView keeps increasing referencing solely _UIInputViewContent. class KeyboardViewController: UIInputViewController { // Callbacks var key1: ((String) -> Void)? var key2: (() -> Void)? var key3: (() -> Void)? var key4: (() -> Void)? private lazy var buttonTitles = [ ["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"] ] override func viewDidLoad() { super.viewDidLoad() setupKeyboard() } lazy var mainStackView: UIStackView = { let mainStackView = UIStackView() mainStackView.axis = .vertical mainStackView.distribution = .fillEqually mainStackView.spacing = 16 mainStackView.translatesAutoresizingMaskIntoConstraints = false return mainStackView }() private func setupKeyboard() { let keyboardView = UIView(frame:CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 279.0)) keyboardView.addSubview(mainStackView) NSLayoutConstraint.activate([ mainStackView.topAnchor.constraint(equalTo: keyboardView.topAnchor, constant: 16), mainStackView.leadingAnchor.constraint(equalTo: keyboardView.leadingAnchor, constant: 0), mainStackView.trailingAnchor.constraint(equalTo: keyboardView.trailingAnchor, constant: -24), mainStackView.bottomAnchor.constraint(equalTo: keyboardView.bottomAnchor, constant: -35) ]) // Create rows for (_, _) in buttonTitles.enumerated() { let rowStackView = UIStackView() rowStackView.axis = .horizontal rowStackView.distribution = .fillEqually rowStackView.spacing = 1 // Create buttons for each row for title in rowTitles { let button = createButton(title: title) rowStackView.addArrangedSubview(button) } mainStackView.addArrangedSubview(rowStackView) } self.view = keyboardView } private func createButton(title: String) -> UIButton { switch title { ///returns a uibutton based on title } } // MARK: - Button Actions @objc private func numberTapped(_ sender: UIButton) { if let number = sender.title(for: .normal) { key1?(number) } } @objc private func key2Called() { key2?() } @objc private func key3Called() { key3?() } @objc private func key4Called() { key4?() } deinit { // Clear any strong references key1 = nil key2 = nil key3 = nil key4 = nil for subview in mainStackView.arrangedSubviews { if let stackView = subview as?

Hello. I use NavigationStack for navigating in app. I have 4 screens - A, B, C, D. In some moment I have path [A, B, C] for NavigationStack. After user did action I should show path [A, B, D]. In other hands I should replace screen C with screen D. struct HomeView: View { @ObservedObject var viewModel: HomeViewModel var body: some View { NavigationStack(path: $viewModel.path) { ContentView() .navigationDestination(for: HomeViewModel.Path.self) { destination in // B, C, D views here... } } .navigationViewStyle(StackNavigationViewStyle()) } } Solution looks like same as for UIKit. I replaced last item in stack. It works, but "push" animation broke. var updatedPath = self.path updatedPath.removeLast() updatedPath.append(newPathItem) self.path = updatedPath I found suggest in Internet that you can remove view from stack after some delay. But it has some magic. For example 1 second delay works properly on iOS 18, but cause crash on iOS 16. 1 millisecond delay works on iOS 16, but sometimes didn't. self.path.append(newPathItem) DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1000)) { UIView.setAnimationsEnabled(false) self.path.remove(at: self.path.count - 2) DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1)) { UIView.setAnimationsEnabled(true) } } It is easy task to replace current top screen in UINavigationController of UIKit. How I can do it properly in SwiftUI and save animation?

When I present a view controller, whose view is a SwiftUI View, via presentAsModalWindow(_:) the presented window is no longer centered horizontally to the screen, but rather its origin is there. I know this issue occurs for macOS 15.2+, but can't tell if it is from 15.0+. I couldn't find any documentation on why was this changed. Here's an example code that represents my architecture: class RootViewController: NSViewController { private lazy var button: NSButton = NSButton( title: "Present", target: self, action: #selector(presentView)) override func viewDidLoad() { super.viewDidLoad() // Add button to tree } @objc func presentView() { presentAsModalWindow(PresentedViewController()) } } class PresentedViewController: NSViewController { override loadView() { view = NSHostingView(rootView: MyView()) } } struct MyView: View { /* impl */ }

Various TextField and TextView elements of Apple apps have text edit actions for text correction, but also auto completion. How can I create such a menu for a TextField in SwiftUI on macOS? the textCompletion modifier did not result in this menu. Many thanks in advance! Jan

In SwiftUI for macOS, how can I animate the transition from one Tab to another Tab within TabView when the selection changes? In AppKit, we can do the following: let tabViewController = NSTabViewController() tabViewController.transitionOptions = [.crossfade, .allowUserInteraction] How can I achieve the same crossfade effect when using TabView?

Background Color Issue in Custom Keyboard Extension in Dark Mode for iOS 18.4.1 Issue Description I'm developing a custom keyboard extension for iOS 18.4.1 and experiencing an issue with background colors when using Dark Mode. After a user makes a selection from a menu in the keyboard, the background color of a view unexpectedly changes to white instead of maintaining the dark theme color. Steps to Reproduce Enable Dark Mode on the device Activate the custom keyboard in any text field Perform a specific interaction (selecting an item from a menu) After selection, the background of the view turns white instead of remaining dark Technical Details The issue appears to be related to UIScrollView's background color behavior The problem doesn't occur on initial display of the menu, only after user interaction I've attempted to set background colors explicitly on the view hierarchy, but the issue persists Environment iOS 18.4.1 Xcode 16.0 Custom keyboard extension Questions Has anyone encountered similar issues with view background colors changing after user interactions in keyboard extensions on iOS 18.4.1? Is there a recommended approach to maintain dark background colors in keyboard extensions after user selections? Could this be related to a change in how UIScrollView handles background colors in recent iOS versions? Thank you for any assistance or insights.

Dear all, Sorry if the topic has already been commented but I could not be able to find it in over 10,000 picks using the forum search field...

I have an app that run Monte Carlo simulations. I run thousands of simulations in the app and a simulation runs can take on the order of 30 seconds to a minute to complete. I would like to have a progress view that tracks the number of simulation runs. How can I implement this in swiftui?

In my CarPlay app, I am hiding the navigation bar by using the following: self.mapTemplate?.automaticallyHidesNavigationBar = true self.mapTemplate?.hidesButtonsWithNavigationBar = false I don't want the navigation bar to show unless a user interacts with the map by tapping it. Strangely, when I present a CPNavigationAlert the navigation bar will often appear and then disappear after the alert is dismissed. Is there a setting or reason that the navigation bar would be appearing when presenting this alert? I would like to keep the nav bar hidden during this time.

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?
