My Mac app uses many NSTextViews just fine for printing a long string, but trying to do the same on iOS with many UITextViews and associated UIViewPrintFormatters just causes a crash.*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x00007fff23c7127e __exceptionPreprocess + 350 1 libobjc.A.dylib 0x00007fff513fbb20 objc_exception_throw + 48 2 CoreFoundation 0x00007fff23d03ab1 _CFThrowFormattedException + 194 3 CoreFoundation 0x00007fff23b83bf9 -[__NSArrayM objectAtIndex:] + 169 4 UIKitCore 0x00007fff48029503 -[UITextViewPrintFormatter rectForPageAtIndex:] + 86 5 UIKitCore 0x00007fff4806bc79 __57-[UIPrintPageRenderer drawPrintFormatter:forPageAtIndex:]_block_invoke + 41 6 UIKitCore 0x00007fff4806bcf9 __57-[UIPrintPageRenderer drawPrintFormatter:forPageAtIndex:]_block_invoke.43 + 29 7 libdispatch.dylib 0x000000010e4f6d48 _dispatch_client_callout + 8 8 libdispatch.dylib 0x000000010e505b24 _dispatch_async_and_wait_invoke + 175 9 libdispatch.dylib 0x000000010e4f6d48 _dispatch_client_callout + 8 10 libdispatch.dylib 0x000000010e504de6 _dispatch_main_queue_callback_4CF + 1500 11 CoreFoundation 0x00007fff23bd4049 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 9 12 CoreFoundation 0x00007fff23bceca9 __CFRunLoopRun + 2329 13 CoreFoundation 0x00007fff23bce066 CFRunLoopRunSpecific + 438 14 GraphicsServices 0x00007fff384c0bb0 GSEventRunModal + 65 15 UIKitCore 0x00007fff48092d4d UIApplicationMain + 1621 16 myApp 0x000000010e1ca61b main + 75 17 libdyld.dylib 0x00007fff5227ec25 start + 1 18 ??? 0x0000000000000001 0x0 + 1 )Here's the code:class ViewController: UIViewController { override func viewDidAppear(_ animated: Bool) { let printController = UIPrintInteractionController.shared let printPageRenderer = PrintPageRenderer() printController.printPageRenderer = printPageRenderer printController.present(animated: true) } } class PrintPageRenderer: UIPrintPageRenderer { let layoutManager = NSLayoutManager() let textStorage = NSTextStorage(string: "fhdjksalhfj dskla fjf") var textViews = [UITextView]() override func prepare(forDrawingPages range: NSRange) { DispatchQueue.main.sync { for (i, textView) in textViews.enumerated() { let printFormatter = textView.viewPrintFormatter() addPrintFormatter(printFormatter, startingAtPageAt: i) } } } override var numberOfPages: Int { textStorage.addLayoutManager(layoutManager) let size = CGFloat(50) for _ in 0..<2 { let textContainer = NSTextContainer(size: CGSize(width: size, height: size)) layoutManager.addTextContainer(textContainer) let textView = UITextView(frame: CGRect(x: 0, y: 0, width: size, height: size), textContainer: textContainer) textViews.append(textView) } return textViews.count } }My goal is printing a document from an attributed string and showing a custom header and footer on each page.

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.

In my app I have a main context A and a sub-context B which has A as its parent. In context B I insert many objects that are rarely needed, so I would like to just write them to disk without keeping them in memory. Currently I call contextB.reset() which frees some memory, but those objects still exist in context A. How can I wipe them out of context A without permanently deleting them and without affecting all the other entities that I fetch using context A? I cannot call contextA.reset() because then all the entity references that I still need become invalid, but I couldn't find a way of making a context selectively forget about entities.

Since March of 2020 Feedback Assistant started showing messages inside of feedbacks in the wrong order. For feedbacks where I respond shortly after a message from Apple, my response is actually shown before Apple's response, so that it is quite difficult reading those old reports. I haven't heard anything from Apple since, and this issue still happens. I keep hearing from the Apple support that Apple really cares about feedback, but why does it take so long to solve an issue that makes it so difficult handling and providing additional feedback?

I already filed a bug report for this issue in January 2020, but without a response until now. It keeps happening that while I'm typing a response to an issue, the text gets reset without reason and I have to type it all over again. Why does nobody care about fixing such annoying issues?

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?

This code strangely doesn't animate the fStop: cameraNode.camera!.wantsDepthOfField = true cameraNode.camera!.focusDistance = 2 let animation = CABasicAnimation(keyPath: "fStop") animation.toValue = 0.5 animation.duration = 0.3 cameraNode.camera!.addAnimation(animation, forKey: nil) while this one does: SCNTransaction.begin() SCNTransaction.animationDuration = 0.3 cameraNode.camera!.fStop = 0.5 SCNTransaction.commit() Why?

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?
