Hello, I work on a video streaming app, and I have been working on this crash that we are seeing quite frequently (it is our #2 crasher at the moment). The stack trace indicates that an AVPictureInPictureController is being deallocated on a background thread. This leads to dangling AutoLayout constraints getting cleaned up, further resulting in an exception being thrown from the framework about the layout engine being accessed from a background thread. We have internal analytics which indicate that the crash occurs after the user comes back to the app after putting it in the background, and switches playback from Picture in Picture mode back to the app's regular playback UI. What has me puzzled here is that, as I'm sure you know, we have no control over the PIP UI. It is entirely system-provided, and there is none of our app's code in the stack trace. The whole process is even initiated by a KVO on an AVPlayerController property, and our app doesn't use that class directly anywhere. So how did we manage to cause this process to happen on a background thread? Add to this the fact that the bug only appeared once we switched to compiling with Xcode 16, and is overwhelmingly present only on devices running iOS 18. These factors lead me to believe that this is probably an OS issue. But before I go to file a feedback, I thought I would post here in case anyone has any ideas. I have attached an instance of the crash log to this post. 2025-01-08_17-32-45.7003_-0800-ea8d5c3323e0f1fc059cf83f6ec86377bdae1788.crash

A new app I have submitted to Apple App Review for iOS/tvOS/macOS has been rejected for tvOS because it is apparently crashing on launch. The same build has been approved by App Review for iOS and macOS. So far, App Review have not provided me with a crash report, and despite a lot of trying, I cannot get the crash to occur either on a real device or on any version of the Apple TV in the simulator. Apart from constantly asking App Review for the crash report, I don't know how to resolve this, and that means I either have to give up on tvOS for this app, delay the launch, or perhaps start another submission and get lucky with a different reviewer that doesn't experience the crash (but then what if lots of users do?). I've tried running a release build on my devices and the simulator; but I'm not sure how I'm supposed to debug this without a crash to work with. The TestFlight build for the same upload that is crashing for App Review works just fine. Any suggestions would be welcome.

I have an iOS application view that contains an AVCaptureSession, AVCaptureVideoPreviewLayer (created with the AVCaptureSession), and a UIImageView (in the backend the app takes the output of the AVCaptureSession, runs it through a Semantic Segmentation model, and displays the output in the UIImageView). When I pause the app and run the “Debug View Hierarchy”, it shows the UIImageView, the relevant buttons and labels. However, it does not seem to show AVCaptureVideoPreviewLayer that I have set up in my application. Is there some special set up that needs to be done to be able to view Camera Related features? The following is part of the view code, a component that is used to render the AVCaptureVideoPreviewLayer (not sure if this is enough, please let me know if its not): class CameraViewController: UIViewController { var session: AVCaptureSession? var frameRect: CGRect = CGRect() var rootLayer: CALayer! = nil private var previewLayer: AVCaptureVideoPreviewLayer! = nil init(session: AVCaptureSession) { self.session = session super.init(nibName: nil, bundle: nil) } required init?(coder: NSCoder) { super.init(coder: coder) } override func viewDidLoad() { super.viewDidLoad() setUp(session: session!) } private func setUp(session: AVCaptureSession) { previewLayer = AVCaptureVideoPreviewLayer(session: session) previewLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill previewLayer.frame = self.frameRect DispatchQueue.main.async { [weak self] in self!.view.layer.addSublayer(self!.previewLayer) //self!.view.layer.addSublayer(self!.detectionLayer) } } } struct HostedCameraViewController: UIViewControllerRepresentable{ var session: AVCaptureSession! var frameRect: CGRect func makeUIViewController(context: Context) -> CameraViewController { let viewController = CameraViewController(session: session) viewController.frameRect = frameRect return viewController } func updateUIViewController(_ uiView: CameraViewController, context: Context) { } }

Run on Xcode Unchecked Scheme -> Run -> 'Debug excitable' is fine. But, I need the debug log, how to fix?

I am currently studying the Accelerate library by referring to Apple documentation. Here is the link to the referenced document: https://developer.apple.com/documentation/accelerate/veclib/vforce When I executed the sample code provided at the bottom of the document, I found a case where the results were different. let n = 10_000 let x = (0..<n).map { _ in Float.random(in: 1 ... 10_000) } let y = x.map { return sqrt($0) } and let y = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in vForce.sqrt(x, result: &buffer) initializedCount = n } The code below is provided to observe the issue described above. import Accelerate Task { let n = 1//10_000 let x = (0..<n).map { _ in Float(6737.015)//Float.random(in: 1 ... 10_000) } let y = x.map { return sqrt($0) } try? await Task.sleep(nanoseconds: 1_000_000_000) let z = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in vForce.sqrt(x, result: &buffer) initializedCount = n } } For a value of 6737.015 when calculating the square root: Using the sqrt(_:) function gives the result 82.07932, While using the vForce.sqrt(_:result:) function gives the result 82.07933. Using a calculator, the value comes out as 82.07932139, which shows that the result from vForce is incorrect. Could you explain the reason behind this difference?

Hey there! Hope you are starting the year with great joy. My situation I'm building a new product that is based on detecting certain text on screen in realtime. The product is only targeted for Mac and it's built with Swift My problem I need to get the exact position of a text element with the Apple Accessibility API but I can't figurate it out. I managed to get the AXUIElement where the text is placed but it's position is too broad and off target. My discoveries so far I've tried OCR but is too slow for what I'm building, so the only possible way I can think of is with the Accessibility API. Thank you in advanced.

When user opened my application, it crashed immediately.

I'm trying to add an iMessage extension to my app, and upon adding the iMessage App Icon set, I ran into an issue with one specific icon size: 1024x768px, aka 1x 1024x768pt. When I remove this one icon from the icon set, it compiles and runs fine, however I can't push it to the App Store as I get the error: "Asset validation failed. Missing Image Asset. Your app is missing the Large App Icon asset 'AppIcon' in 'Payload/Runner.app/PlugIns/MessagesExtension.appex'." I'm assuming this refers to 1024x768px, as this size placeholder appears upon adding a New Messages Extension Icon to my assets folder, and 1024x1024 is already included and compiles fine with it. However, when I add the 1024x768 icon, and try to run the app, I get the error: "Command CompileAssetCatalog failed with a nonzero exit code" The app icon's filename is correct, it is exactly 1024x768 px, and my contents.json correctly includes : { "filename" : "AppIcon_1024x768.png", "idiom" : "ios-marketing", "platform" : "ios", "scale" : "1x", "size" : "1024x768" } as is the same format for all of my other icons that work. Why am I running into this issue upon inclusion of this one required size? How do I fix it?

I already asked this, although I want to ask again so it boots and gets more people; When I try to run my project on the simulator, it tells me there is a bug. It is not in the code I wrote, but I believe in the compiler. It would work perfectly, say the build succeeded, but the phone turns white and stops there. I don't know how to debunk it, what to do! Picture of what happens with the phone: Picture of the debugging area: Picture of my code: If I need to add more things, please let me know. Have a great day!

Hello Apple engineers, could you help me understand whether this crash is a UIKit bug or something in our code that causes it. Based on the documentation it is an invalid fetch instruction, that's why I suspect UIKit. I've found a similar crash here on the forums reported a year ago, it seemed to be a UIKit bug - https://forums.developer.apple.com/forums/thread/729448.
