Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

I would like to implement zoom functionality in my SceneKit game: when the user performs the pinch gesture on a point on the screen, the scene zooms in to make that point larger. Until now I simply changed SCNCamera.focalLength, but this simply zooms in to the center of what is currently visible on screen. Is it somehow possible to implement the zoom functionality described above by perhaps interactively rotating the camera at the same time towards the pinched point? Is there a formula for this? I would like to avoid suddenly rotating the camera to face the pinched point when the pinch gesture begins and then zoom in while the pinch is in progress.

I have a very basic App Intent extension in my macOS app that does nothing than accepting two parameters, but running it in Shortcuts always produces the error "The action “Compare” could not run because an internal error occurred.". What am I doing wrong? struct CompareIntent: AppIntent { static let title = LocalizedStringResource("intent.compare.title") static let description = IntentDescription("intent.compare.description") static let openAppWhenRun = true @Parameter(title: "intent.compare.parameter.original") var original: String @Parameter(title: "intent.compare.parameter.modified") var modified: String func perform() async throws -> some IntentResult { return .result() } }

The Verify the behavior of your intent in Simulator or on-device documentation says that it's sufficient to build and run the app and open the Shortcuts app to test an app intent, but that doesn't seem to be the case. I always needed to at least move the debugged app to the Applications folder before the app intents showed up in Shortcuts, and even then, most of the times I also need to wait a lot or restart the Mac. When updating an existing app intent (for instance by changing its title), building the app, overwriting the existing one in the Applications folder and restarting Shortcuts is not sufficient to make the new title appear in Shortcuts. Is there an efficient way to test app intents in the Shortcuts app? I already created FB15638502 one month ago but got no response.

I rarely use the Shortcuts app, so it took me a while to notice that my app's app intents all show incorrectly on macOS 15. On macOS 14 and 13, they used to show correctly, but now it seems that all localized strings show the key rather than the localized value. @available(iOS 16.0, macOS 13.0, *) struct MyAppIntent: AppIntent { static let title = LocalizedStringResource("key1", comment: "") static let description = IntentDescription(LocalizedStringResource("key2", comment: "")) ... } In Localizable.xcstrings file I have defined all the strings, for instance I have associated key1 with the value Title, but while the Shortcuts app used to display Title, it now displays key1. Is this a known issue or did something change in macOS 15 that would require me to update something?

When running the sample code below, every 3 seconds the middle sprite is replaced by a new one. When this happens, most of the time a flicker is noticeable. When recording the screen and stepping through the recording frame by frame, I noticed that the flicker is caused by a temporary reordering of the nodes’. Below you find two screenshots of two consecutive frames where the reordering is clearly visible. This only happens for a SpriteKit scene used as an overlay for a SceneKit scene. Commenting out buttons.zPosition = 1 or avoiding the fade in/out animations solves the issue. I have created FB15945016. import SceneKit import SpriteKit class GameViewController: NSViewController { let overlay = SKScene() var buttons: SKNode! var previousButton: SKSpriteNode! var nextButton: SKSpriteNode! var pageContainer: SKNode! var pageViews = [SKNode]() var page = 0 override func viewDidLoad() { super.viewDidLoad() let scene = SCNScene(named: "art.scnassets/ship.scn")! let scnView = self.view as! SCNView scnView.scene = scene overlay.anchorPoint = CGPoint(x: 0.5, y: 0.5) scnView.overlaySKScene = overlay buttons = SKNode() buttons.zPosition = 1 overlay.addChild(buttons) previousButton = SKSpriteNode(systemImage: "arrow.uturn.backward.circle") previousButton.position = CGPoint(x: -100, y: 0) buttons.addChild(previousButton) nextButton = SKSpriteNode(systemImage: "arrow.uturn.forward.circle") nextButton.position = CGPoint(x: 100, y: 0) buttons.addChild(nextButton) pageContainer = SKNode() pageViews = [SKSpriteNode(systemImage: "square.and.arrow.up"), SKSpriteNode(systemImage: "eraser")] overlay.addChild(pageContainer) setPage(0) Timer.scheduledTimer(withTimeInterval: 3, repeats: true) { [self] _ in setPage((page + 1) % 2) } } func setPage(_ page: Int) { pageViews[self.page].run(.sequence([ .fadeOut(withDuration: 0.2), .removeFromParent() ]), withKey: "fade") self.page = page let pageView = pageViews[page] pageView.alpha = 0 pageView.run(.fadeIn(withDuration: 0.2), withKey: "fade") pageContainer.addChild(pageView) } override func viewDidLayout() { overlay.size = view.frame.size } } extension SKSpriteNode { public convenience init(systemImage: String) { self.init() let width = 100.0 let image = NSImage(systemSymbolName: systemImage, accessibilityDescription: nil)!.withSymbolConfiguration(.init(hierarchicalColor: NSColor.black))! let scale = NSScreen.main!.backingScaleFactor image.size = CGSize(width: width * scale, height: width / image.size.width * image.size.height * scale) texture = SKTexture(image: image) size = CGSize(width: width, height: width / image.size.width * image.size.height) } }

I was able to confirm with a customer of mine that calling copyfile with a source file that is a symbolic link on a NTFS partition always causes the error NSPOSIXErrorDomain 12 Cannot allocate memory They use NTFS drivers from Paragon. They tried copying a symbolic link from NTFS to both APFS and NTFS with the same result. Is this an issue with macOS, or with the NTFS driver? Copying regular files on the other hand always works. Copying manually from the Finder also seems to always work, both with regular files and symbolic links, so I'm wondering how the Finder does it. Here is the sample app that they used to reproduce the issue. The first open panel allows to select the source directory and the second one the destination directory. The variable filename holds the name of the symbolic link to be copied from the source to the destination. Apparently it's not possible to select a symbolic link directly in NSOpenPanel, as it always resolves to the linked file. @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ notification: Notification) { let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true openPanel.canChooseFiles = false openPanel.runModal() let filename = "Modules" let source = openPanel.urls[0].appendingPathComponent(filename) openPanel.runModal() let destination = openPanel.urls[0].appendingPathComponent(filename) do { let state = copyfile_state_alloc() defer { copyfile_state_free(state) } var bsize = UInt32(16_777_216) if copyfile_state_set(state, UInt32(COPYFILE_STATE_BSIZE), &bsize) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } if copyfile_state_set(state, UInt32(COPYFILE_STATE_STATUS_CB), unsafeBitCast(copyfileCallback, to: UnsafeRawPointer.self)) != 0 || copyfile_state_set(state, UInt32(COPYFILE_STATE_STATUS_CTX), unsafeBitCast(self, to: UnsafeRawPointer.self)) != 0 || copyfile(source.path, destination.path, state, copyfile_flags_t(COPYFILE_NOFOLLOW)) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } } catch { let error = error as NSError let alert = NSAlert() alert.messageText = "\(error.localizedDescription)\n\(error.domain) \(error.code)" alert.runModal() } } private let copyfileCallback: copyfile_callback_t = { what, stage, state, src, dst, ctx in if what == COPYFILE_COPY_DATA { if stage == COPYFILE_ERR { return COPYFILE_QUIT } var size: off_t = 0 copyfile_state_get(state, UInt32(COPYFILE_STATE_COPIED), &size) } return COPYFILE_CONTINUE } }

In my SceneKit game I'm able to connect two players with GKMatchmakerViewController. Now I want to support the scenario where one of them disconnects and wants to reconnect. I tried to do this with this code: nonisolated public func match(_ match: GKMatch, player: GKPlayer, didChange state: GKPlayerConnectionState) { Task { @MainActor in switch state { case .connected: break case .disconnected, .unknown: let matchRequest = GKMatchRequest() matchRequest.recipients = [player] do { try await GKMatchmaker.shared().addPlayers(to: match, matchRequest: matchRequest) } catch { } @unknown default: break } } } nonisolated public func player(_ player: GKPlayer, didAccept invite: GKInvite) { guard let viewController = GKMatchmakerViewController(invite: invite) else { return } viewController.matchmakerDelegate = self present(viewController) } But after presenting the view controller with GKMatchmakerViewController(invite:), nothing else happens. I would expect matchmakerViewController(_:didFind:) to be called, or how would I get an instance of GKMatch? Here is the code I use to reproduce the issue, and below the reproduction steps. Code Run the attached project on an iPad and a Mac simultaneously. On both devices, tap the ship to connect to GameCenter. Create an automatched match by tapping the rightmost icon on both devices. When the two devices are matched, on iPad close the dialog and tap on the ship to disconnect from GameCenter. Wait some time until the Mac detects the disconnect and automatically sends an invitation to join again. When the notification arrives on the iPad, tap it, then tap the ship to connect to GameCenter again. The iPad receives the call player(_:didAccept:), but nothing else, so there’s no way to get a GKMatch instance again.

In the past, I used to export a developer-signed test version of my macOS app in Xcode, create a zip archive from the Finder, upload it to my website and share the link to the testers. The last time I did this with macOS 14 the tester was still able to download the test app and run it. But it seems that with macOS 15 the trick to open the context menu on the downloaded app and click Open to bypass the macOS warning that the app couldn't be checked when simply double-clicking it, doesn't work anymore. Now I'm always shown an alert that macOS couldn't check the app for malware, and pushes me to move it to the bin. In this StackOverflow topic from 10 years ago they suggested to use ditto and tar to compress and uncompress the app, but neither worked for me. How can I share macOS apps that I signed myself with testers without physically handing them a drive containing the uncompressed app?

I would like to preload and use some images for both SpriteKit and SceneKit models (my game uses SceneKit with a SpriteKit overlay), and as far as I can see the only efficient way would be to create and preload SKTexture objects which can be supplied to SKSpriteNode(texture:) and SCNMaterial.diffuse.contents. The problem is that SKTexture are rendered too bright in SceneKit, for some unknown reason. Here a comparison between rendering an image (from URL) and a SKTexture: And the code that produces it: let url = Bundle.main.url(forResource: "art.scnassets/texture.png", withExtension: nil)! let plane1 = SCNPlane(width: 10, height: 10) plane1.firstMaterial!.diffuse.contents = url.path let node1 = SCNNode(geometry: plane1) node1.position.x = -5 scene.rootNode.addChildNode(node1) let plane2 = SCNPlane(width: 10, height: 10) plane2.firstMaterial!.diffuse.contents = SKTexture(image: NSImage(byReferencing: url)) let node2 = SCNNode(geometry: plane2) node2.position.x = 5 scene.rootNode.addChildNode(node2) This issue was already mentioned in this other post, but since I wasn't notified of the reply from Quinn asking about the feedback number I created at the time, it didn't make any progress.

I'm trying to create the app icon for my visionOS app. The Assets catalog already contains AppIcon for iOS and I've added another AppIcon for visionOS. If I only add the Back layer of the visionOS icon, compiling succeeds despite there being an error The visionOS App Icon "AppIcon" must have at least 2 layers with applicable content. Although it has 3 layers, only 1 has applicable content. As soon as I add one of the other two layers, say the Front layer, compiling fails, but this time Xcode only shows a generic compiler error Command CompileAssetCatalogVariant emitted errors but did not return a nonzero exit code to indicate failure If I click that message, a long build log opens containing among other things: 2024-10-31 11:28:15.258 AssetCatalogSimulatorAgent[66919:1456355] -[TDTextureRawRenditionSpec _createImageRefWithURL:andDocument:format:] Texture image asset file:///~/Documents/apps/myApp/xcode/iOS/Assets.xcassets/AppIcon.solidimagestack/Back.solidimagestacklayer/Content.imageset/icon_layer3.heic not in one of supported formats ... libc++abi: terminating due to uncaught exception of type NSException Command CompileAssetCatalogVariant failed with a nonzero exit code What is the problem? I filed FB15642844.

To make UI testing easier and faster, I usually create URL bookmarks during normal app usage in the Simulator so that they can be instantly resolved on app launch during UI tests. For example, one of my apps allows browsing selected folders and stores bookmarks so they can be quickly opened again on following app launches, and instead of selecting the test folder each time at the beginning of the UI test, I select it once during normal app usage so that it's available immediately during the UI test. This usually works fine, but every now and then the UI tests fail because the tested app isn't able to resolve the stored bookmark. I don't know why this happens, but usually opening and closing the app again in the Simulator and re-running the UI tests solves the issue. The problem now is that I've just tried to setup some new UI tests for Apple Vision Pro Simulator and I'm never able to resolve bookmarks. So I created a sample project that reproduces the issue, and curiously enough the bookmarks don't even resolve when using an iPad Simulator (which usually works fine with my regular UI tests). What am I doing wrong? This can be reproduced with a default iOS project, embedding the default storyboard view controller in a navigation view controller, and this code: import UIKit class ViewController: UIViewController, UIDocumentPickerDelegate { override func viewDidLoad() { navigationItem.rightBarButtonItem = UIBarButtonItem(systemItem: .add, primaryAction: UIAction(handler: { _ in let picker = UIDocumentPickerViewController(forOpeningContentTypes: [.folder]) picker.delegate = self self.present(picker, animated: true) })) if let bookmark = UserDefaults.standard.data(forKey: "bookmark") { readBookmark(bookmark) } } func readBookmark(_ bookmark: Data) { do { let label = UILabel(frame: CGRect(x: 100, y: 100, width: 600, height: 100)) label.numberOfLines = 0 var stale = false let url = try URL(resolvingBookmarkData: bookmark, bookmarkDataIsStale: &stale) if !url.startAccessingSecurityScopedResource() { fatalError() } label.text = url.path view.addSubview(label) } catch { fatalError(error.localizedDescription) } } func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) { do { let url = urls[0] if !url.startAccessingSecurityScopedResource() { fatalError() } let bookmark = try url.bookmarkData() UserDefaults.standard.set(bookmark, forKey: "bookmark") readBookmark(bookmark) } catch { fatalError(error.localizedDescription) } } } And a default UI test, which always crashes because of the fatalError() in the catch clause of readBookmark(_:): final class problemUITests: XCTestCase { @MainActor func testExample() throws { let app = XCUIApplication() app.launch() } }

I'm trying to close the UIFontPickerViewController in a UI test by tapping the close button in the navigation bar. In a default iOS app, I embed the default storyboard view controller in a navigation view controller, then in code I open the font picker like this: class ViewController: UIViewController, UIFontPickerViewControllerDelegate { override func viewDidAppear(_ animated: Bool) { let picker = UIFontPickerViewController(configuration: .init()) picker.delegate = self self.present(picker, animated: true) } func fontPickerViewControllerDidPickFont(_ viewController: UIFontPickerViewController) { } } And the UI test looks like this: final class problemUITests: XCTestCase { @MainActor func testExample() throws { let app = XCUIApplication() app.launch() sleep(2) let button = app.navigationBars.element(boundBy: 1).buttons.element(boundBy: 0) print(button.debugDescription) XCTAssert(button.waitForExistence(timeout: 2)) button.tap() } } When running the UI test, the XCTAssert always fails and the button.tap() also fails with an error message Failed to tap "chiudi" Button: No matches found for Element at index 1 from input {( NavigationBar )} "chiudi" means "close" in Italian, my macOS system language. It sounds to me like I correctly get the close button, but the messages Xcode prints make no sense to me. It's particularly confusing given that the output of the print statement shows that the button is there, but somehow fails to be tapped: Attributes: Button, 0x104f44660, {{701.0, 320.0}, {43.0, 44.0}}, label: 'chiudi' Element subtree: →Button, 0x104f44660, {{701.0, 320.0}, {43.0, 44.0}}, label: 'chiudi' Image, 0x104f44780, {{709.0, 327.5}, {30.0, 30.0}}, identifier: 'UICloseButtonBackground' Path to element: →Application, 0x104f35940, pid: 29803, label: 'problem' ↳Window (Main), 0x104f376a0, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f42e10, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43100, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43220, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43340, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43460, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43580, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f436a0, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f437c0, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f438e0, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43a00, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43b20, {{0.0, 0.0}, {1032.0, 1376.0}} ↳Other, 0x104f43c40, {{276.0, 314.0}, {480.0, 748.0}} ↳Other, 0x104f43e80, {{276.0, 314.0}, {480.0, 748.0}} ↳Other, 0x104f43fa0, {{276.0, 314.0}, {480.0, 748.0}} ↳Other, 0x104f440c0, {{276.0, 314.0}, {480.0, 748.0}} ↳Other, 0x104f441e0, {{276.0, 314.0}, {480.0, 748.0}} ↳Other, 0x104f44300, {{276.0, 314.0}, {480.0, 748.0}} ↳NavigationBar, 0x104f44420, {{276.0, 314.0}, {480.0, 108.0}}, identifier: 'Scegli font' ↳Button, 0x104f44660, {{701.0, 320.0}, {43.0, 44.0}}, label: 'chiudi' Query chain: →Find: Target Application 'org.desairem.problem' Output: { Application, 0x104f781b0, pid: 29803, label: 'problem' } ↪︎Find: Descendants matching type NavigationBar Output: { NavigationBar, 0x10607c0d0, {{0.0, 24.0}, {1032.0, 50.0}}, identifier: 'UIFontPickerView' NavigationBar, 0x10607dab0, {{276.0, 314.0}, {480.0, 108.0}}, identifier: 'Scegli font' } ↪︎Find: Element at index 1 Output: { NavigationBar, 0x1064693a0, {{276.0, 314.0}, {480.0, 108.0}}, identifier: 'Scegli font' } ↪︎Find: Descendants matching type Button Output: { Button, 0x104f714a0, {{701.0, 320.0}, {43.0, 44.0}}, label: 'chiudi' Button, 0x104f71800, {{711.0, 378.0}, {17.0, 22.0}}, identifier: 'Dictate', label: 'Avvia dettatura' } ↪︎Find: Element at index 0 Output: { Button, 0x104f5d5e0, {{701.0, 320.0}, {43.0, 44.0}}, label: 'chiudi' }

I've been running my SceneKit game for many weeks in Xcode without performance issues. The game itself is finished, so I thought I could go on with publishing it on the App Store, but when archiving it in Xcode and running the archived app, I noticed that it seriously hangs. The hangs only seem to happen when I run the game in fullscreen mode. I tried disabling game mode, but the hangs still happen. Only when I run in windowed mode the game runs smoothly. Instruments confirms that there are many serious hangs, but it also reports that CPU usage is quite low during those hangs, on average about 15%. From what I know, hangs happen when the main thread is busy, but how can that be when CPU usage is so low, and why does it only happen in fullscreen mode for release builds?

I'm trying to display a right-aligned timecode in my game. I had expected that digits would all have the same width, but this doesn't seem to be the case in SpriteKit, even though it seems to be the case in AppKit. In SpriteKit, with the default font there is a noticeable difference in width between the digit 1 and the rest (1 is thinner), so whenever displaying a number with the least significant digit 1 all preceding digits shift slightly to the right. This happens even when setting a NSAttributedString with a font that has a fixedAdvance attribute. class GameScene: SKScene { override func didMove(to view: SKView) { let label = SKLabelNode(text: "") view.scene!.addChild(label) // label.horizontalAlignmentMode = .left label.horizontalAlignmentMode = .right var i = 11 Timer.scheduledTimer(withTimeInterval: 0.5, repeats: true) { _ in label.text = "\(i)" // let font = NSFont(descriptor: NSFontDescriptor(fontAttributes: [.name: "HelveticaNeue-UltraLight", .fixedAdvance: 20]), size: 30)! // let paragraphStyle = NSMutableParagraphStyle() // paragraphStyle.alignment = .right // label.attributedText = NSAttributedString(string: "\(i)", attributes: [.font: font, .foregroundColor: SKColor.labelColor, .paragraphStyle: paragraphStyle]) i += 5 } } } With AppKit, when using SpriteKit's default font HelveticaNeue-UltraLight, this issue doesn't exist, regardless whether I set the fixedAdvance font attribute. class ViewController: NSViewController { override func viewDidLoad() { super.viewDidLoad() let font = NSFont(descriptor: NSFontDescriptor(fontAttributes: [.name: "HelveticaNeue-UltraLight"]), size: 30)! // let font = NSFont(descriptor: NSFontDescriptor(fontAttributes: [.name: "HelveticaNeue-Light", .fixedAdvance: 20]), size: 30)! let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.alignment = .right let textField = NSTextField(labelWithString: "") textField.font = font textField.alignment = .right // textField.alignment = .left textField.frame = CGRect(x: 100, y: 100, width: 100, height: 100) view.addSubview(textField) var i = 11 Timer.scheduledTimer(withTimeInterval: 0.5, repeats: true) { _ in textField.stringValue = "\(i)" // textField.attributedStringValue = NSAttributedString(string: "\(i)", attributes: [.font: font, .paragraphStyle: paragraphStyle]) i += 5 } } } Is there a solution to this problem? I filed FB15553700.
