According to the docs: The first time your app performs an operation that requires [photo library] authorization, the system automatically and asynchronously prompts the user for it. (https://developer.apple.com/documentation/photokit/delivering-an-enhanced-privacy-experience-in-your-photos-app) I.e. it's not necessary for the app to call PHPhotoLibrary.requestAuthorization. This does seem to be what happens when my app runs on an iPhone or iPad; the prompt is shown. But when it runs on a Mac in "designed for iPad" mode, the permission dialog is not presented. Instead the code continues to see status == .notDetermined. That's today, on macOS 15.3. It may have worked in the past. Is anyone else seeing issues with this? Should I call requestAuthorization explicitly? (Would that actually work?)

Hello, I'm wondering how to capture 24MP photos. I'm currently testing on an iPhone 16 Pro Max. By default, the device's activeFormat supports 24MP (photo dimensions: {4032x3024, 5712x4284}). For the photoOutput, I'm setting the maxPhotoDimensions to videoDevice.activeFormat.supportedMaxPhotoDimensions.lastObject, and setting MaxPhotoQualityPrioritization to quality. When capturing, I'm applying the same maxPhotoDimensions and photoQualityPrioritization settings from the photoOutput directly to the AVCapturePhotoSettings. What could be the issue? // Objective-C // setup [self.photoOutput setMaxPhotoQualityPrioritization:AVCapturePhotoQualityPrioritizationQuality]; CMVideoDimensions maxPhotoDimensions = [(NSValue *)videoDevice.activeFormat.supportedMaxPhotoDimensions.lastObject CMVideoDimensionsValue]; [self.photoOutput setMaxPhotoDimensions:maxPhotoDimensions]; // capturing AVCapturePhotoSettings *photoSettings = [AVCapturePhotoSettings photoSettings]; photoSettings.maxPhotoDimensions = self.photoOutput.maxPhotoDimensions; photoSettings.photoQualityPrioritization = self.photoOutput.maxPhotoQualityPrioritization; [self.photoOutput capturePhotoWithSettings:photoSettings delegate:photoCaptureDelegate]; ...

Hello Apple Community, We are working on a real-time streaming feature where we receive chunks of raw MP4 data through a custom protocol and store them in a buffer (array). Our goal is to use these data chunks to play a continuous video stream in AVPlayer. What We've Tried: Custom URL Scheme with AVAssetResourceLoaderDelegate: We implemented a custom URL scheme (customscheme://) to serve the buffered data using AVAssetResourceLoaderDelegate. The method shouldWaitForLoadingOfRequestedResource is called only during the initial allocation. It doesn't get triggered when new chunks are appended to the buffer. Despite appending new data to the buffer, AVPlayer doesn’t request further chunks from the delegate. What We Need: We are looking for a solution where: The player continuously fetches data from the buffer as new chunks are added. The playback remains smooth and uninterrupted, even with real-time data being appended. Ideally, this solution works with AVPlayer while adhering to HLS-like behavior without implementing an HLS server. Questions: Is AVAssetResourceLoaderDelegate the right approach for this use case? If so, how can we ensure shouldWaitForLoadingOfRequestedResource is called whenever new data is available in the buffer? Are there alternative APIs or recommended patterns for playing real-time MP4 data chunks in AVPlayer? Would implementing a custom FFmpeg-based player be necessary, or can this be achieved using AVPlayer and its APIs? We appreciate any guidance, suggestions, or examples that can help us achieve this. Thank you!

Hello there, I need to move through video loaded in an AVPlayer one frame at a time back or forth. For that I tried to use AVPlayerItem's method step(byCount:) and it works just fine. However I need to know when stepping happened and as far as I observed it is not immediate using the method. If I check the currentTime() just after calling the method it's the same and if I do it slightly later (depending of the video itself) it shows the correct "jumped" time. To achieve my goal I tried subclassing AVPlayerItem and implement my own async method utilizing NotificationCenter and the timeJumpedNotification assuming it would deliver it as the time actually jumps but it's not the case. Here is my "stripped" and simplified version of the custom Player Item: import AVFoundation final class PlayerItem: AVPlayerItem { private var jumpCompletion: ( (CMTime) -> () )? override init(asset: AVAsset, automaticallyLoadedAssetKeys: [String]?) { super .init(asset: asset, automaticallyLoadedAssetKeys: automaticallyLoadedAssetKeys) NotificationCenter.default.addObserver(self, selector: #selector(timeDidChange(_:)), name: AVPlayerItem.timeJumpedNotification, object: self) } deinit { NotificationCenter.default.removeObserver(self, name: AVPlayerItem.timeJumpedNotification, object: self) jumpCompletion = nil } @discardableResult func step(by count: Int) async -> CMTime { await withCheckedContinuation { continuation in step(by: count) { time in continuation.resume(returning: time) } } } func step(by count: Int, completion: @escaping ( (CMTime) -> () )) { guard jumpCompletion == nil else { completion(currentTime()) return } jumpCompletion = completion step(byCount: count) } @objc private func timeDidChange(_ notification: Notification) { switch notification.name { case AVPlayerItem.timeJumpedNotification where notification.object as? AVPlayerItem [==](https://www.example.com/) self: jumpCompletion?(currentTime()) jumpCompletion = nil default: return } } } In short the notification never gets called thus the above is not working. I guess the key there is that in the docs about the timeJumpedNotification: is said: "A notification the system posts when a player item’s time changes discontinuously." so the step(byCount:) is not considered as discontinuous operation and doesn't trigger it. I'd be really helpful if somebody can help as I don't want to use seek(to:toleranceBefore:toleranceAfter:) mainly cause it's not accurate in terms of the exact next/previous frame as the video might have VFR and that causes repeating frames sometimes or even skipping one or another. Thanks a lot

Our app filters the photo library to a certain date range for ease of picking photos. However, to do this, we have to require full permissions to the photo library. We would like to use the PHPickerViewController and have it filter the results by the assets creation date? This would allow us to use it. I see other filter options, but not this one. And if it isn't there, is this something that is being thought about or on a roadmap?

I'm building a camera app that does some post processing after the photo has been taken. With 12MP the processing is pretty good, but larger images 24MP is very slow. I created a very simple example to demonstrate the issue, which is loading an image and the rendering it to data. let context = CIContext() let imageUrl = Bundle.main.url(forResource: "12mp", withExtension: "jpg")! let data = try! Data(contentsOf: imageUrl) let ciImage = CIImage(data: data)! let start = CFAbsoluteTimeGetCurrent() let data = context.jpegRepresentation(of: ciImage, colorSpace: context.workingColorSpace!) print(data?.count) print("Resize Completed: " + String(CFAbsoluteTimeGetCurrent() - start)) Running this code on an iPhone 16 Pro with different images produces these benchmarks: 12MP => 0.03s 24MP => 1.22s 48MP => 2.98s I understand that processing time will increase with resolution but it doesn't seem linear. I have tried setting different CiContext options such as .useSoftwareRenderer: false but it has made no difference. From profiling the process it looks like the JPEG decoding is the bottle neck. This is for a 48MP Image: Is there any way this can be improved?

I have a SwiftUI app that needs to be able to receive photos and videos from the Photos app. When the user shares an item from the Photos app they can choose to share to a destination app. When doing so from the Files app, my app appears as a share destination and the .onOpenURL successfully handles the incoming content. The CFBundleTypeName and CFBundleTypeRole have been configured accordingly. What I don't understand is why I can share from the Files app and select my app as the destination, while not being able to select my app when sharing from the Photos app. What does the Photos app require to allow a given app to available as a share destination? I'd also like to be able to do this from other apps such as the YouTube app.

Forgot to turn off the ui element status bar. visual garbage. is it not important? your opinion https://developer.apple.com/hello/december24/?cid=ht-hello

I'm a new app developer and am trying to add a button that adds pictures from the photo library AND camera. I added the first function (adding pictures from the photo library) using the new-ish photoPicker, but I can't find a way to do the same thing for the camera. Should I just tough it out and use the UI View Controller struct that I've seen in all of the YouTube tutorials I've come across? I also want the user to be able to crop the picture in the app after they take a picture. Thanks in advance

I'm developing a tutorial style tvOS app with multiple videos. The examples I've seen so far deal with only one video. Defining the player and source(url) before body view let avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../video.mp4")!)) and then in the body view the video is displayed VideoPlayer(player: avPlayer) This allows options such as stop/start etc. When I try something similar with a video title passed into this view I can't define the player with this title variable. var vTitle: String var avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../" + vTitle + ".mp4"")!)) var body: some View { I het an error that vTitle can't be used in the url above the body view. Any thoughts or suggestions? Thanks

I’m building a camera app using SwiftUI and UIKit (with UIViewControllerRepsrwsentable). My app already is able to capture photos, but I also want to implement the important feature - apply my custom image filter to the image for live preview in camera and when this image is saving to the photo library (like in the default Apple camera app with Photographic styles). My image filter must be pretty advanced because I’m a photographer and I trying to achieve the same colours as I have with my custom image preset in Lightroom. I want to control the image parameters such as basic (exposure, contrast, shadows, etc.), tone curves for each channel (Red, Green, Blue channels separately), HSL (for Red, Orange, Yellow, Green, Blue, Aqua, Purple and Magenta), apply colour grading and more. Currently I’m straggling with implementation of this. I tried to create a custom image filter using Metal (it works with saturation) but I’m not sure if it is the best approach. I need help and recommendations of how developers implement this complex thing in their apps (what technologies should I use and etc.)

I’ve not been able to save stickers ever since getting the iPhone 16. I can long click a picture and click “add sticker” but it only stays for a bout a second and disappears. Alternatively I can use the ”add sticker button” on the stickers widget and It will stay while the widget is open but does not remain ready for use. Please help, this has been going on for at least 2 months. Video Icloud Link: https://share.icloud.com/photos/004_0xVjBtdAPYzaHl9rH8Jcw

Since the OS was recently updated to 18.1.1 on my iPhone 15, I am no longer able to import my pictures into the Photos app on my iMac. I have to mention that my iMac is pretty old and is running OS High Sierra 10.13.6 and is not allowing me to update the OS to a newer version. Anyway, the main error message I get is: "Some items cannot be added to your Photo library because they may be an unrecognizable file format or the file may not contain valid data". Then, for each individual photo that failed to upload, the error message I get reads, "unable to read metadata. The file may be corrupt". However, videos import just fine from my iPhone to iMac. This was not a problem before the recent iPhone update. I tried closing the Photo app and reopening it. I tried restarting my iPhone and iMac but nothing seems to work. Any help would be much appreciated.

Hi everyone, I'm developing a customization tool in which our customer can upload a mp3 or mp4 file that will be scannable through our AR application. On desktop and Android, this is working perfectly. For some reason however, on iPhone we're unable to load most of the video files. I've checked the clips, and they are .mov/h.264 files which are supported by iPhone. We're currently not sure how we can fix this issue to allow customers that own an iPhone to upload clips to our website. Any tips in the right direction are more than welcome. thanks in advance!

Hi, In the downloadable WWDC sample project "CreatingASpaceshipGame" there is an audio file named "WorkMusic.aiff", as well mentioned in the video. Info says it's PCM 4-channel Quadrophonic. Where can I find further information on how this file was authored? Was it simply exported from Logic Pro with Quadrophonic Surround settings or did it have any other specific treatment? Thanks, Axel

I am an artist (singer songwriter) and I use the Photos app to manage albums related to my various creative projects. And these are some BIG issues that i am SURPRISED never came into the account or maybe were overlooked - Missing Search Bar When Adding Photos to Albums: Why there is no search bar when adding a photo to a bag of hundred of albums? (Artists like me like to organise things into different albums and folders) I can no longer search for albums by name after ios 18 update, which was previously very helpful in quickly locating them. Albums can be arranged & moved in the same folder but there is no way to move albums between DIFFERENT FOLDERS and the only wat is to create a new album in that folder and select and transfer everything and delete that old album.

Hi! I recently updated to the latest 18.2 Beta version of iOS on my iPhone 15 Pro Max. Could you please guide me on how to locate and utilize the Image Search feature powered by Apple Intelligence? Just a little detail: I went on YouTube and the instruction was to hold the camera action button on the iPhone 16 and image search appears. So far, I haven’t been able to replicate these results on my iPhone 15 Pro Max. This is a great capability and I’d really like to try it out. “Live long and prosper.” -Spock -Jordan

I was able to obtain the depth map image using AVCapturePhotoOutput from the delegate method func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) I convert the depth map to kCVPixelFormatType_DepthFloat32 format and get the pixel values of the depth map using the below code func convertDepthData(depthMap: CVPixelBuffer) -> [[Float32]] { let width = CVPixelBufferGetWidth(depthMap) let height = CVPixelBufferGetHeight(depthMap) var convertedDepthMap: [[Float32]] = Array( repeating: Array(repeating: 0, count: width), count: height ) CVPixelBufferLockBaseAddress(depthMap, CVPixelBufferLockFlags(rawValue: 2)) let floatBuffer = unsafeBitCast( CVPixelBufferGetBaseAddress(depthMap), to: UnsafeMutablePointer<Float32>.self ) for row in 0 ..< height { for col in 0 ..< width { if floatBuffer[width * row + col].isFinite{ convertedDepthMap[row][col] = floatBuffer[width * row + col] } } } CVPixelBufferUnlockBaseAddress(depthMap, CVPixelBufferLockFlags(rawValue: 2)) return convertedDepthMap } Is this the right way of accessing the depth float values from a depth map. And what will be the unit for it. Because some times the depth values are in range of 0.7 when I keep the device close to the subject around 15 to 30 cm.

I'm trying to capture the depth map image using true depth camera in iPhone 15 plus. I was able to setup the AVCapture session with AVCaptureDeviceInput as builtInTrueDepthCamera and AVCapturePhotoOutput with isDepthDataDeliveryEnabled set as true. I also manually made the activeDepthDataFormat of AVCapture device to kCVPixelFormatType_DepthFloat16 or kCVPixelFormatType_DepthFloat32. Finally I have enabled isDepthDataDeliveryEnabled, embedsDepthDataInPhoto , embedsPortraitEffectsMatteInPhoto and embedsSemanticSegmentationMattesInPhoto in AVCapturePhotoSettings before capturing the photo using capturePhoto(with: photoSettings, delegate: self) method. I have checked manually printing the activeDepthDataFormat of AVCapture device. First before setting it by default it is Optional('dpth'/'hdis' 640x 480, { 2- 30 fps}, photo dims:{}, fov:73.699, system exposure bias range:-2.0-2.0) After forcing it to kCVPixelFormatType_DepthFloat16 or kCVPixelFormatType_DepthFloat32 the format is Optional('dpth'/'hdep' 160x 120, { 2- 30 fps}, photo dims:{}, fov:73.699, system exposure bias range:-2.0-2.0) But when I receive the captured photo in func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) The depth map is Optional(hdis 640x480 (high/abs) calibration:{intrinsicMatrix: [2723.07 0.00 2016.00 | 0.00 2723.07 1512.00 | 0.00 0.00 1.00], extrinsicMatrix: [1.00 0.00 0.00 0.00 | 0.00 1.00 0.00 0.00 | 0.00 0.00 1.00 0.00] pixelSize:0.001 mm, distortionCenter:{2016.00,1512.00}, ref:{4032x3024}}) Here it shows hdis instead of hdep, why is it capturing disparity map instead of true depth map. The depth quality is high and depth data accuracy is absolute. Here is my code import UIKit import AVKit import AVFoundation class ViewController: UIViewController, AVCapturePhotoCaptureDelegate { @IBOutlet weak var previewView: UIView! @IBOutlet weak var resultLbl: UILabel! private var session = AVCaptureSession() private var captureDevice: AVCaptureDevice? private var inputDevice: AVCaptureDeviceInput? private var photoOutput: AVCapturePhotoOutput? private var photoSettings: AVCapturePhotoSettings? private var cameraPreviewLayer: AVCaptureVideoPreviewLayer? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. self.setupCaptureSession() } func setupCaptureSession(){ captureDevice = AVCaptureDevice.default(.builtInTrueDepthCamera, for: .video, position: .unspecified) guard let captureDevice else{ print("ERROR::UNABLE TO SET TRUE DEPTH CAMERA ") return } session.beginConfiguration() do{ inputDevice = try AVCaptureDeviceInput(device: captureDevice) guard let inputDevice else{ print("ERROR: UNABLE TO SET UP INPUT DEVICE") return } if session.canAddInput(inputDevice){ session.addInput(inputDevice) } } catch{ print(error) } photoOutput = AVCapturePhotoOutput() guard let photoOutput else{ print("ERROR: UNABLE TO SET UP PHOTO OUTPUT") return } if session.canAddOutput(photoOutput){ session.addOutput(photoOutput) } session.sessionPreset = .photo photoOutput.isDepthDataDeliveryEnabled = photoOutput.isDepthDataDeliverySupported print("IS DEPTH ENABLED:: \(photoOutput.isDepthDataDeliveryEnabled)") session.commitConfiguration() let availableFormats = captureDevice.activeFormat.supportedDepthDataFormats let depthFormat = availableFormats.filter { format in let pixelFormatType = CMFormatDescriptionGetMediaSubType(format.formatDescription) return (pixelFormatType == kCVPixelFormatType_DepthFloat16 || pixelFormatType == kCVPixelFormatType_DepthFloat32) }.first session.beginConfiguration() try! captureDevice.lockForConfiguration() captureDevice.activeDepthDataFormat = depthFormat captureDevice.unlockForConfiguration() session.commitConfiguration() self.setupPreviewLayer() } func setupPreviewLayer(){ cameraPreviewLayer = AVCaptureVideoPreviewLayer(session: session) cameraPreviewLayer?.videoGravity = .resizeAspectFill if let cameraPreviewLayer{ self.previewView.layer.addSublayer(cameraPreviewLayer) cameraPreviewLayer.frame = self.previewView.bounds } DispatchQueue.global(qos: .userInteractive).async { self.session.startRunning() } } @IBAction func captureBtnPressed(_ sender: Any) { photoSettings = AVCapturePhotoSettings(format: [AVVideoCodecKey:AVVideoCodecType.jpeg]) guard let photoSettings else{ print("ERROR: UNABLE TO SETUP PHOTO SETTINGS") return } guard let photoOutput else{ print("ERROR: UNABLE TO SET UP PHOTO OUTPUT") return } photoSettings.isDepthDataDeliveryEnabled = photoOutput.isDepthDataDeliverySupported photoSettings.embedsDepthDataInPhoto = true photoSettings.embedsPortraitEffectsMatteInPhoto = true photoSettings.embedsSemanticSegmentationMattesInPhoto = true photoOutput.capturePhoto(with: photoSettings, delegate: self) } func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) { print(photo.depthData) switch photo.depthData?.depthDataQuality { case .low: print("Depth quality is low") case .high: print("Depth quality is high") case nil: print("Depth quality is nil") } switch photo.depthData?.depthDataAccuracy { case .relative: print("Depth accuarcy is relative") case .absolute: print("Depth accuarcy is absolute") case nil: print("Depth accuarcy is nil") } if let imageData = photo.fileDataRepresentation(){ if let image = UIImage(data: imageData){ UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil) } } } }

When trying to edit some Live Photos, calling PHLivePhotoEditingContext.saveLivePhoto results in the following error: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-12815), NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x300d05380 {Error Domain=NSOSStatusErrorDomain Code=-12815 "(null)"}} I was able to replicate it on my device by taking a new Live Photo. Not sure what's wrong with that one specifically, not all Live Photos replicate the issue. I've submitted FB15880825 with a sysdiagnose and a Photos Diagnostics as well. Any ideas what's going on here? It's impacting multiple customers. Thanks!
