I have the main app that saves preferences to UserDefaults.standard. So I have this one preference that the user is able to toggle - isRawOn UserDefaults.standard.set(self.isRawOn, forKey: "isRawOn") Now, I have LockedCameraCaptureExtension which is required know if that above setting on or off during launch. Also if it's toggled within the extension, the main app should know about it on the next launch. The main app and the extension runs on separate containers and the preferences are not shared due to privacy reasons. Apple mentions of using appContext of CameraCaptureIntent, but not sure how above scenario is possible through that....unless I am missing something. Apple Reference What I have for CameraCaptureIntent: @available(iOS 18, *) struct LaunchMyAppControlIntent: CameraCaptureIntent { typealias AppContext = MyAppContext static let title: LocalizedStringResource = "LaunchMyAppControlIntent" static let description = IntentDescription("Capture photos with MyApp.") @MainActor func perform() async throws -> some IntentResult { .result() } }

1.May I ask if the Background Upload can run normally in the Release version of ios 26.1? I used the Release version of ios 26.1 for debugging and found that the background upload couldn't be triggered for a long time. I debugged in ios 26.2 and found that background upload could be triggered normally, but kept triggering an Error: "Error returned from daemon: error Domain=com.apple.accounts Code=7 "(null)"

Apple Watch app closes when changing photo permissions in the iPhone app. App A is installed simultaneously on both the paired iPhone and Apple Watch. I'm running App A on both my iPhone and Apple Watch. When I change the photo permissions on App A installed on my iPhone, App A running on my Apple Watch automatically closes. At first, I assumed App A on my iPhone was abnormally closing, causing App A on my Apple Watch to also close. However, I've determined that changing the photo permissions is the cause of the app closing. I don't think this behavior existed before WatchOS/iOS 26. Is this behavior a natural addition to WatchOS/iOS 26? If I go to the home screen while running app A on my iPhone and change its photo permissions in the Settings app, app A running on my Apple Watch automatically closes.

Recently Apple gave us the possibility to upload asset resources in the background. We implemented our background upload extension but when our CI tried to upload the app on TestFlight we got an error that the extension point identifier - in our case com.apple.photos.backgound-upload - is not an official one. Any idea when it will become official and we will be able to release a working background uploading?

I'm trying to benchmark a Core Image filter chains memory footprint and notice a weird quirk in instruments. On a real device, even with a simple Core Image chain, the memory balloons each time I ran the filter. See attached screen shots. Running on iPhone 17 Pro: Running on simulator (M2 Macbook Pro) As you can see there's a huge build up of 4MB "VM: IOSurface" memory on the real device, but the simulator seems to clean it up correctly. Here's my basic code: func processImage() { guard let inputImage = ContentViewModel.loadImageFromBundle(name: "kitty.HEIC") else { print("Failed to load sample_image from bundle") return } var outputImage = inputImage outputImage = outputImage.applyingFilter("CIBloom", parameters: [ kCIInputRadiusKey: 20, kCIInputIntensityKey: 0.8 ]) DispatchQueue.global(qos: .userInitiated).async { let data = self.context.jpegRepresentation(of: outputImage, colorSpace: CGColorSpace(name: CGColorSpace.sRGB)!) if let data = data, let uiImage = UIImage(data: data) { DispatchQueue.main.async { self.displayImage = Image(uiImage: uiImage) } } } } Why is this happening? Seems like a bug to me or I need to release an object. At the very least makes it challenging to measure memory usage. Any help is greatly appreciated. Alex

Device: iPhone 17 Pro iOS Version: iOS 26.1 Camera: Ultra-wide (0.5x) using AVCaptureSession Our camera app freezes on iPhone 17 when switching frame rates (30fps ↔ 60fps). This works fine on iPhone 16 Pro and earlier. What We've Observed: Freeze happens on frame rate change - particularly when stabilization was enabled Thread.sleep is used - to allow camera hardware to settle before re-enabling stabilization Works on older iPhones - only iPhone 17 exhibits this behavior Console shows these errors before freeze: 17281 <<<< FigXPCUtilities >>>> signalled err=18446744073709534335 <<<< FigCaptureSourceRemote >>>> err=-17281 Is Thread.sleep on the main thread causing the freeze? Should all camera configuration be on a background queue? Is there something specific about iPhone 17 ultra-wide camera that requires different handling? Should we use session.beginConfiguration() / session.commitConfiguration() instead of direct device configuration? Is calling setFrameRate from a property's didSet (which runs synchronously) problematic? Are the FigCaptureSourceRemote errors (-17281) indicative of the problem, and what do they mean?

Hello, I am getting the following error while attempting to run my LockedCameraCapture compatible app on an iOS 15 device: dyld[434]: Library not loaded: '/System/Library/Frameworks/LockedCameraCapture.framework/LockedCameraCapture' Referenced from: '/private/var/containers/Bundle/Application/.../MyApp.app/MyApp.debug.dylib' Reason: tried: '/System/Library/Frameworks/LockedCameraCapture.framework/LockedCameraCapture' (no such file) Of course iOS 15 doesn't have the library for LockedCameraCapture, but I have had no issue including Lock Screen Widgets (which require iOS 16), so I am not sure why the error is popping up. Thank you!

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.)

is forKey:fileSize considered accessing non-public API? has your app been rejected at review stage due to this? let resources = PHAssetResource.assetResources(for: asset) if let resource = resources.first { if let fileSize = resource.value(forKey: "fileSize") as? Int { return fileSize } }

Hey, I'm building a camera app and I want to use the captured HDRGainMap along side the photo to do some processing with a CIFilter chain. How can this be done? I can't find any documentation any where on this, only on how to access the HDRGainMap from an existing HEIC file, which I have done successfully. For this I'm doing something like the following: let gainmap = CGImageSourceCopyAuxiliaryDataInfoAtIndex(source, 0, kCGImageAuxiliaryDataTypeHDRGainMap) let gainDict = NSDictionary(dictionary: gainmap) let gainData = gainDict[kCGImageAuxiliaryDataInfoData] as? Data let gainDescription = gainDict[kCGImageAuxiliaryDataInfoDataDescription] let gainMeta = gainDict[kCGImageAuxiliaryDataInfoMetadata] However I'm not sure what the approach is with a AVCapturePhoto output from a AVCaptureDevice. Thanks!

I'm developing an iOS app using AVFoundation for real-time video capture and object detection. While implementing torch functionality with camera switching (between Wide and Ultra-Wide lenses), I encountered a critical issue where the camera freezes when toggling the torch while the Ultra-Wide camera is active. Issue If the torch is ON and I switch from Wide to Ultra-Wide, the camera freezes If the Ultra-Wide camera is active and I try to turn the torch ON, the camera freezes The iPhone Camera app allows using the torch while recording video with the Ultra-Wide lens, so this should be possible via AVFoundation as well. Code snippet DispatchQueue.global(qos: .userInitiated).async { [weak self] in guard let self = self else { return } let isSwitchingToUltraWide = !self.isUsingFisheyeCamera let cameraType: AVCaptureDevice.DeviceType = isSwitchingToUltraWide ? .builtInUltraWideCamera : .builtInWideAngleCamera let cameraName = isSwitchingToUltraWide ? "Ultra Wide" : "Wide" guard let selectedCamera = AVCaptureDevice.default(cameraType, for: .video, position: .back) else { DispatchQueue.main.async { self.showAlert(title: "Camera Error", message: "\(cameraName) camera is not available on this device.") } return } do { let currentInput = self.videoCapture.captureSession.inputs.first as? AVCaptureDeviceInput self.videoCapture.captureSession.beginConfiguration() if isSwitchingToUltraWide &amp;&amp; self.isFlashlightOn { self.forceEnableTorchThroughWide() } if let currentInput = currentInput { self.videoCapture.captureSession.removeInput(currentInput) } let videoInput = try AVCaptureDeviceInput(device: selectedCamera) self.videoCapture.captureSession.addInput(videoInput) self.videoCapture.captureSession.commitConfiguration() self.videoCapture.updateVideoOrientation() DispatchQueue.main.async { if let barButton = sender as? UIBarButtonItem { barButton.title = isSwitchingToUltraWide ? "Wide" : "Ultra Wide" barButton.tintColor = isSwitchingToUltraWide ? UIColor.systemGreen : UIColor.white } print("Switched to \(cameraName) camera.") } self.isUsingFisheyeCamera.toggle() } catch { DispatchQueue.main.async { self.showAlert(title: "Camera Error", message: "Failed to switch to \(cameraName) camera: \(error.localizedDescription)") } } } } Expected Behavior Torch should be able to work when Ultra-Wide is active, just like the iPhone Camera app does. The camera should not freeze when switching between Wide and Ultra-Wide with the torch ON. AVCaptureSession should not crash when toggling the torch while Ultra-Wide is active. Questions &amp; Help Needed Is this a known issue with AVFoundation? How does the iPhone Camera app allow using the torch while recording in Ultra-Wide? What’s the correct way to switch between Wide and Ultra-Wide cameras without freezing when the torch is active?

I’ve never had a problem with any update before but as soon as I updated to 18.3 update my camera decided to start blurring when it’s in 1x & 2x, I use my camera daily for work and this is unacceptable. I’m wondering if anyone else is having this issue, it’s really frustrating..

I am trying to use AVCaptureDevice.rotationCoordinator API to observe angles for preview and capture and it seems there is an issue with the API when used with arbitrary CALayer (which is not a AVCaptureVideoPreviewLayer) and switching cameras. Here is my setup. The below function is defined in an actor class called CameraManager that performs setup of rotationCoordinator. func updateRotationCoordinator(_ callback:@escaping @MainActor (CGFloat) -> Void) { guard let device = sessionConfiguration.activeVideoInput?.device, let displayLayer = displayLayer else { return } cancellables.removeAll() rotationCoordinator = AVCaptureDevice.RotationCoordinator(device: device, previewLayer: displayLayer) guard let coordinator = rotationCoordinator else { return } coordinator.publisher(for: \.videoRotationAngleForHorizonLevelPreview) .receive(on: DispatchQueue.main) .sink { degrees in let radians = degrees * .pi / 180 MainActor.assumeIsolated { callback(radians) } } .store(in: &cancellables) } This works the very first time but when I switch cameras and call this function again, it throws a runtime error that view's layer is modified from a non-main thread. This happens at the very line where rotation coordinator is been recreated. It's not clear why initialising rotation coordinator should modify CALayer properties right in it's init method. Modifying properties of a view's layer off the main thread is not allowed: view <MyApp.DisplayLayerView: 0x102ffaf40> with nearest ancestor view controller <_TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier__: 0x101f7fb80>; backtrace: ( 0 UIKitCore 0x0000000194a977b4 575E5140-FA6A-37C2-B00B-A4EACEDFDA53 + 22509492 1 UIKitCore 0x000000019358594c 575E5140-FA6A-37C2-B00B-A4EACEDFDA53 + 416076 2 QuartzCore 0x00000001927f5bd8 D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 43992 3 QuartzCore 0x00000001927f5a4c D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 43596 4 QuartzCore 0x000000019283a41c D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 324636 5 QuartzCore 0x000000019283a0a8 D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 323752 6 AVFCapture 0x00000001af072a18 09192166-E0B6-346C-B1C2-7C95C3EFF7F7 + 420376 7 MyApp.debug.dylib 0x0000000105fa3914 $s10MyApp15CapturePipelineC25updateRotationCoordinatoryyy12CoreGraphics7CGFloatVScMYccF + 972 8 MyApp.debug.dylib 0x00000001063ade40 $s10MyApp11CameraModelC18switchVideoDevicesyyYaFTY3_ + 72 9 MyApp.debug.dylib 0x0000000105fe3cbd $s10MyApp11ContentViewV4bodyQrvg7SwiftUI6VStackVyAE05TupleE0VyAE6HStackVyAIyAE6SpacerV_AE6ButtonVyAE0E0PAEE5frame5width6height9alignmentQr12CoreGraphics7CGFloatVSg_AyE9AlignmentVtFQOyAqEE11scaledToFitQryFQOyAqEE10imageScaleyQrAE5ImageV0Z0OFQOyA3__Qo__Qo__Qo_GtGG_AmKyAIyAKyAIyAqEE7paddingyQrAE4EdgeO3SetV_AYtFQOyAA07CaptureM0V_Qo__AOyAE4TextVGAmKyAIyA9__AqEEArstUQrAY_AYA_tFQOyAM_Qo_A9_tGGtGG_AmqEE10background_AUQrqd___A_tAePRd__lFQOyAqEEArstUQrAY_AYA_tFQOyA21__Qo__AqEEArstUQrAY_AYA_tFQOyAE06_ShapeE0VyAE9RectangleVAE5ColorVG_Qo_Qo_SgtGGtGGyXEfU0_A42_yXEfU_A10_yXEfU_yyScMYccfU_yyYacfU_TQ1_ + 1 10 MyApp.debug.dylib 0x0000000105ff06d9 $s10MyApp11ContentViewV4bodyQrvg7SwiftUI6VStackVyAE05TupleE0VyAE6HStackVyAIyAE6SpacerV_AE6ButtonVyAE0E0PAEE5frame5width6height9alignmentQr12CoreGraphics7CGFloatVSg_AyE9AlignmentVtFQOyAqEE11scaledToFitQryFQOyAqEE10imageScaleyQrAE5ImageV0Z0OFQOyA3__Qo__Qo__Qo_GtGG_AmKyAIyAKyAIyAqEE7paddingyQrAE4EdgeO3SetV_AYtFQOyAA07CaptureM0V_Qo__AOyAE4TextVGAmKyAIyA9__AqEEArstUQrAY_AYA_tFQOyAM_Qo_A9_tGGtGG_AmqEE10background_AUQrqd___A_tAePRd__lFQOyAqEEArstUQrAY_AYA_tFQOyA21__Qo__AqEEArstUQrAY_AYA_tFQOyAE06_ShapeE0VyAE9RectangleVAE5ColorVG_Qo_Qo_SgtGGtGGyXEfU0_A42_yXEfU_A10_yXEfU_yyScMYccfU_yyYacfU_TATQ0_ + 1 11 MyApp.debug.dylib 0x0000000105f9c595 $sxIeAgHr_xs5Error_pIegHrzo_s8SendableRzs5NeverORs_r0_lTRTQ0_ + 1 12 MyApp.debug.dylib 0x0000000105f9fb3d $sxIeAgHr_xs5Error_pIegHrzo_s8SendableRzs5NeverORs_r0_lTRTATQ0_ + 1 13 libswift_Concurrency.dylib 0x000000019c49fe39 E15CC6EE-9354-3CE5-AF91-F641CA8283E0 + 433721 )

Hi, I’m working on a photo backup app. I track the PHAsset localIdentifier to determine which photos have been backed up and which haven’t. Recently, I’ve noticed that two users seem to have experienced the localIdentifier changes after transferring data to a new iPhone using Quick Start. Additionally, others on StackOverflow have mentioned that the localIdentifier sometimes changes after updating the iOS version. https://stackoverflow.com/questions/40094728/phobject-localidentifier-reliability I’d like to confirm the reliability of the localIdentifier after an iOS version upgrade or device transfer. Can I continue using these locally stored localIdentifiers? Or is there another recommended approach, such as using PHCloudIdentifier?

I would appreciate help in coding or an explanation what to use in swift for an app which will be able to capture LiDAR scanning and RGB data from taken pictures, generate a 3D mesh, and create .OBJ, .MTL, and .JPEG file set for further manipulation of 3D model.

Hi This is one of our top crashes. It does not contain any of our code in the stacktrace and we can't reproduce it. Those points make this crash very hard to understand and fix. We know that most of the crashes are happening on iPhone 13 with iOS 18.x.x. Also we see that a lot of cases happen when app goes into background (stacktrace contains -[UIApplication _applicationDidEnterBackground]). 2025-03-04_16-06-00.3670_-0500-6a273c7d5da97f098b5cc24898bb9761dc45208e.crash 2025-03-04_20-21-08.6609_-0500-2c08f640900f8a62c4f8a4f6f2a61feb052e66dd.crash 2025-03-04_20-46-27.7138_+0000-4d7ea89b1b564eda22ca63e708f7ad3909c7b768.crash

If new photo is added to library and app is not running in foreground or was not opened after the new photo was added but the app is having full access to gallery, can it access, read the new photo - If the app is not specifically a cloud syncing app, can it have this attached function, suppose it is a game app or beauty camera app?
