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 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

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’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! 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

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!

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.

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) } } } }

I have an app that allows the user to change a photo’s EXIF metadata. To do this, I request a content editing input, get the full size image, modify its properties, create a content editing output, write the output image to the rendered content URL, then call performChanges on the PHPhotoLibrary creating an asset change request for that asset setting its content editing output. This works as expected for regular photos but Live Photos get turned off converted to a regular photo. To address this, I’m doing something similar by changing the properties of the .photo image in the Live Photo. I detect when the content editing input has a Live Photo, create a Live Photo editing context, set a frame processor that returns the frame’s image after setting its properties to the updated properties when the frame type is photo, then I create the content editing output and save the Live Photo to that output. It modifies the Live Photo successfully, but the metadata is not updated. If you get the full size image again the properties are the original properties. If you look at the EXIF metadata using an app like Metapho it remains unchanged. What am I doing wrong here? Thanks! let imageURL = contentEditingInput.fullSizeImageURL! let inputImage = CIImage(contentsOf: imageURL, options: [.applyOrientationProperty: true])! var metadata: [AnyHashable: Any] = inputImage.properties // Edit the metadata as desired... let editingContext = PHLivePhotoEditingContext(livePhotoEditingInput: contentEditingInput)! editingContext.frameProcessor = { frame, error -> CIImage? in // Edit only the still photo if frame.type == .photo { return frame.image.settingProperties(metadata) } return frame.image } let contentEditingOutput = try await withCheckedThrowingContinuation { continuation in let editingOutput = PHContentEditingOutput(contentEditingInput: contentEditingInput) editingOutput.adjustmentData = adjustmentData editingContext.saveLivePhoto(to: editingOutput) { success, error in if success { continuation.resume(returning: editingOutput) } else { continuation.resume(throwing: error!) } } } try await PHPhotoLibrary.shared().performChanges { let request = PHAssetChangeRequest(for: asset) request.contentEditingOutput = contentEditingOutput }

I have an app that allows you to edit your photos. To preserve HDR, I edit both the SDR image and gain map image, like so: let sdrImage = CIImage(data: data, options: [.applyOrientationProperty: true]) let gainMapImage = CIImage(data: data, options: [.applyOrientationProperty: true, .auxiliaryHDRGainMap: true]) // edit them... try CIContext().writeHEIFRepresentation(of: sdrImage, to: url, format: .RGBA8, colorSpace: colorSpace, options: [.hdrGainMapImage: gainMapImage]) I also support editing the still photo in Live Photos. To do this you create a PHLivePhotoEditingContext, set the frameProcessor block which gives you a CIImage that I edit when the frame.type is .photo, then you create a PHContentEditingOutput and call saveLivePhoto. I’m not seeing any way to preserve HDR here. Interestingly the frame processor is called twice with .photo frame.type, but I don’t see any difference between these images. How can I edit a gain map image to preserve HDR in the still photo of a Live Photo?

I tried several times to use the PhotosPickerItem loadTransferable function with the goal of receiving some progress value especially when loading large video media. However, the Progress object returned by the function has always isIndeterminate == true and so doesn't have any progress value to observe. Is there some way to make it work ? Some configuration I might have overlooked ? Or is it just not working I might have to revert back to the UIKit photo picker because of this

I have an webview that loads videos in it, we would like to be able to fullscreen our videos, so we use the fullscreen preference in the documentation however when it is set to true, upon fullscreening a video then pausing it, the entire video player will disappear. You can exit fullscreen and attempt to fullscreen the video player once again, however upon doing this the entire app view will now disappear and you'll see your desktop background (or whatever is currently behind your app). This behavior seems consistent across multiple websites with the current app. I have setup a sample project you can test here The Main error that seems to trigger to the console is this. I have not been able to find a solution to, maybe I am simply missing something here. I am on Sequoia 15.2 for Mac. Attempting to update all DD element frames, but the bounds or contentsRect are invalid. Bounds: X: 0.00 Y: 0.00, W: 0.00 H: 0.00, contentsRect: X: 0.00 Y: 0.00, W: 1.00 H: 1.00 , skipping
