A user of my app brought to my attention that unless they select their ~/Library/Mail folder explicitly in an open panel, they get an error when scanning it inside my app. I can confirm that I also get a permission error when trying to scan it as a subfolder of ~/Library, but not if I select it directly. I'm assuming this is intentional, but it would be nice to have an explanation or some documentation that I can point my users to when they encounter what appears to them as a bug in my app. What makes this matter even more confusing is that selecting a folder in any open panel of an app gives the app access to it for the lifetime of the app, but after restarting the app, access is lost again (unless it has a bookmark to it). This was probably the reason why the user thought that it worked in another app but not in mine. This is the code I use to scan: let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true if openPanel.runModal() == .cancel { return } let enumerator = FileManager.default.enumerator(at: openPanel.urls[0], includingPropertiesForKeys: nil) { url, error in print(url.path, error) return true } while let url = enumerator?.nextObject() as? URL { } And this the error related to the Mail folder: ~/Library/Mail Error Domain=NSCocoaErrorDomain Code=257 "The file “Mail” couldn’t be opened because you don’t have permission to view it." UserInfo={NSURL=file:///~/Library/Mail, NSFilePath=/~/Library/Mail, NSUnderlyingError=0x600002991470 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

In macOS 26 I noticed there is a section Menu Bar in System Settings which allows to toggle visibility of status items created with NSStatusItem. I'm assuming this is new, since I never noticed it before. Currently my app has a menu item that allows toggling its status item, but now I wonder whether it should always create the status item and let the user control its visibility from System Settings. Theoretically, keeping this option inside the app could lead to confusion if the user has previously disabled the status item in System Settings, then perhaps forgot about it, and then tries to enable it inside the app, but apparently nothing happens because System Settings overrides the app setting. Should I remove the option inside the app? This also makes me think of login items, which can be managed both in System Settings and inside the app via SMAppService. Some users ask why my app doesn't have a launch at login option, and I tell them that System Settings already offers that functionality. Since there is SMAppService I could offer an option inside the app that is kept in sync with System Settings, but I prefer to avoid duplicating functionality, particularly if it's something that is changed once by the user and then rarely (if ever) changed afterwards. But I wonder: why can login items be controlled by an app, and the status item cannot (at least I'm not aware of an API that allows to change the option in System Settings)? If the status item can be overridden in System Settings, why do login items behave differently?

macOS 26 sometimes draws the title bar background even when setting NSWindow.titlebarAppearsTransparent = true and I don't understand the logic behind it, or how I can turn this off. I'm trying to do something similar to Xcode's "Welcome to Xcode" window which has a left view and a right table view. In my simplified example, the window contains a label and a text view. This used to work in macOS 15, but in macOS 26 the text view is partially covered by the title bar: As soon as I remove the line scrollView.hasVerticalScroller = true, the title bar isn't drawn anymore: The title bar also isn't drawn when removing the view on the left of the text view: I created FB20341654. This may be related to this other issue: NSWindow.titlebarAppearsTransparent only works after collapsing and expanding sidebar @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { let window = NSWindow(contentViewController: ViewController()) window.titlebarAppearsTransparent = true window.titleVisibility = .hidden window.styleMask = [.titled, .closable, .fullSizeContentView] window.makeKeyAndOrderFront(nil) } } class ViewController: NSViewController { override func loadView() { view = NSView(frame: CGRect(x: 0, y: 0, width: 400, height: 200)) let scrollView = NSScrollView() scrollView.hasVerticalScroller = true // commenting this line out solves the issue scrollView.translatesAutoresizingMaskIntoConstraints = false scrollView.automaticallyAdjustsContentInsets = false let documentView = NSTextView() documentView.string = (0..<10).map({ "\($0)" }).joined(separator: "\n") scrollView.documentView = documentView let stack = NSStackView(views: [ NSTextField(labelWithString: "asdfasdfasdfasdf"), // commenting this line out also solves the issue scrollView ]) stack.orientation = .horizontal view.addSubview(stack) NSLayoutConstraint.activate([stack.topAnchor.constraint(equalTo: view.topAnchor), stack.leadingAnchor.constraint(equalTo: view.leadingAnchor), stack.trailingAnchor.constraint(equalTo: view.trailingAnchor), stack.bottomAnchor.constraint(equalTo: view.bottomAnchor)]) } }

Xcode downloaded a crash report for my app that crashed when trying to insert a String into a Set<String>. Apparently there was an assertion failure ELEMENT_TYPE_OF_SET_VIOLATES_HASHABLE_REQUIREMENTS. I assume that this assertion failure happened because the hash of the new element didn't match the hash of an equal already inserted element, but regardless, I don't understand how inserting a simple string could trigger this assertion. Here is essentially the code that leads to the crash. path is any file system directory, and basePath is a directory higher in the hierarchy, or path itself. var scanErrorPaths = Set<String>() func main() { let path = "/path/to/directory" let basePath = "/path" let fileDescriptor = open(path, O_RDONLY) if fileDescriptor < 0 { if (try? URL(fileURLWithPath: path, isDirectory: false).checkResourceIsReachable()) == true { scanErrorPaths.insert(path.relativePath(from: basePath)!) return } } extension String { func relativePath(from basePath: String) -> String? { if basePath == "" { return self } guard let index = range(of: basePath, options: .anchored)?.upperBound else { return nil } return if index == endIndex || basePath == "/" { String(self[index...]) } else if let index = self[index...].range(of: "/", options: .anchored)?.upperBound { String(self[index...]) } else { nil } } } crash.crash

It seems that timeControlStatus == .paused and rate == 0 when the video is being played fast forward or backward. Is this really how it's supposed to be? If yes, is there a way of knowing if the video is effectively paused?

Can I delete it? Why is it still there? I already created a feedback for this in June but got no response.

I'm trying to record video and audio and sending them over the network so that they can be played back in real time on other clients. I've managed to record and play back video successfully, but audio still cannot be played back (see AVAudioPlayer at the bottom of the code below). What am I doing wrong or what is missing? Thank you in advance for any input. let captureSession = AVCaptureSession() private func startVideoAudioFeed() {     let sessionPreset = AVCaptureSession.Preset.low     if captureSession.canSetSessionPreset(sessionPreset) {         captureSession.sessionPreset = sessionPreset     }     switch AVCaptureDevice.authorizationStatus(for: .video) {     case .notDetermined:         AVCaptureDevice.requestAccess(for: .video) { success in             self.startVideoAudioFeed()         }     case .authorized:         captureSession.beginConfiguration()         let captureVideoDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front)!         let captureVideoInput = try!

By adding this code to the default SceneKit Xcode project, one can reproduce the issue (the default ship object is blurred when viewed directly by the camera, and sharp when viewed through the semi-transparent square): cameraNode.camera!.wantsDepthOfField = true cameraNode.camera!.focusDistance = 2 cameraNode.camera!.fStop = 0.5 let plane = SCNNode(geometry: SCNPlane(width: 1, height: 1)) plane.position = SCNVector3(x: 0.5, y: 0, z: 13) plane.opacity = 0.5 scene.rootNode.addChildNode(plane) Is this something expected, and is there a workaround for making objects seen through semi-transparent objects appear blurred as well?

Since a year or so I get frequent email reminders for feedbacks to which Apple answered and to which I still didn't reply. The interval between Apple's answer and the automatic reminder can be as small as 5 days and are repeated weekly until I respond to them. There is apparently no way of disabling them. How can it be that I have to respond within 5 days and Apple can take up to 8 years (the longest I've waited for a response for now)? I've already reported this several times but to no avail. I would also like to be able to send weekly reminders to Apple for not responding to pressing issues, but unfortunately that's not possible and this comes across as being quite arrogant.

I create a URL bookmark with URL.bookmarkData(options: [], includingResourceValuesForKeys: [.localizedNameKey]) and resolve it with NSURL(resolvingBookmarkData: bookmarkData, options: [], relativeTo: nil, bookmarkDataIsStale: nil) asURL. This works fine within my main app, but when sharing the bookmarkData via an App Group with my Share Extension, it gives the error "The file couldn't be opened because you don't have permission to view it.". Is there any way I can do this?

For a couple of years now Xcode has been showing many similar warnings when opening a storyboard file. I have opened FB8245368 more than a year ago without response. If there is a way of solving these warnings inside the storyboard without adding artificial constraints that are removed at build time? Open the project at https://www.icloud.com/iclouddrive/0bNxa2_8jNRVFbpKsTyrB5yMg#problem Select that warning, then click Update Frames at the bottom right of the canvas. You can keep pressing the button until the view is entirely collapsed.

I haven‘t yet found an official Apple website that lists older macOS versions. Fortunately, I have kept the installers on a separate external storage after each major upgrade, but when launching them from a macOS version newer that the installer itself, macOS shows an error that it‘s not possible to install it. What is the official way of installing older macOS versions so that I can test my App Store apps?

It seems that when typing inside a textview that has insets and padding, the caret keeps jumping up and down on most keystrokes. Is there a solution to this? class ViewController: UIViewController, UITextViewDelegate {     @IBOutlet weak var textView: TextView!     override func viewDidLayoutSubviews() {         let h = textView.bounds.size.height / 2         textView.textContainerInset = UIEdgeInsets(top: h, left: 0, bottom: h, right: 0)         textView.textContainer.lineFragmentPadding = 200     }     func textViewDidChange(_ textView: UITextView) {         textView.textStorage.addAttribute(.foregroundColor, value: UIColor.red, range: NSRange(location: 0, length: 1))     } } class TextView: UITextView {     override func caretRect(for position: UITextPosition) -> CGRect {         let r = super.caretRect(for: position)         print(r)         return r     } } A complete project can be found here: https://www.icloud.com/iclouddrive/0yEBQZPUCZQH1o3HiL8_6q_gQ#problem_copia

Every now and then (say at least once a week, but possibly many times within a day) when I try to deploy to my iPad Xcode shows a sheet reading "iPad is not connected", even if it was working a minute earlier. I have reported this already several months ago, but apparently there is no fix for this yet. Usually, restarting Mac and/or iPad solves the issue, but it's really annoying when I have to do this repeatedly. Is there an easier workaround?
