My implementation of LockedCameraCapture does not launch my app when tapped from locked screen. But when the same widget is in the Control Center, it launches the app successfully. Standard Xcode target template: Lock_Screen_Capture.swift @main struct Lock_Screen_Capture: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Lock_Screen_CaptureViewFinder(session: session) } } } Lock_Screen_CaptureViewFinder.swift: import SwiftUI import UIKit import UniformTypeIdentifiers import LockedCameraCapture struct Lock_Screen_CaptureViewFinder: UIViewControllerRepresentable { let session: LockedCameraCaptureSession var sourceType: UIImagePickerController.SourceType = .camera init(session: LockedCameraCaptureSession) { self.session = session } func makeUIViewController(context: Self.Context) -> UIImagePickerController { let imagePicker = UIImagePickerController() imagePicker.sourceType = sourceType imagePicker.mediaTypes = [UTType.image.identifier, UTType.movie.identifier] imagePicker.cameraDevice = .rear return imagePicker } func updateUIViewController(_ uiViewController: UIImagePickerController, context: Self.Context) { } } Then I have my widget: struct CameraWidgetControl: ControlWidget { var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind: "com.myCompany.myAppName.lock-screen") { ControlWidgetButton(action: MyAppCaptureIntent()) { Label("Capture", systemImage: "camera.shutter.button.fill") } } } } My AppIntent: struct MyAppContext: Codable {} struct MyAppCaptureIntent: CameraCaptureIntent { typealias AppContext = MyAppContext static let title: LocalizedStringResource = "MyAppCaptureIntent" static let description = IntentDescription("Capture photos and videos with MyApp.") @MainActor func perform() async throws -> some IntentResult { .result() } } The Issue LockedCameraCapture Widget does not launch my app when tapped from locked screen. You get the Face ID prompt and takes you to just Home Screen. But when the same widget is in the Control Center, it launches the app successfully. Error Message When tapped on Lock Screen, I get the following error code: LaunchServices: store ‹private > or url ‹private > was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo=&NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied.

Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo=&NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Things I tried Widget image displays correctly App ID and the Provisioning Profile seem to be fine since they work fine when the same code injected in to AVCam sample app and when used the same App ID's. AppIntent file contains the target memberships of the Lock Screen capture and Widget Apple compiles without errors or warnings.

I'm writing a program to control a PTZ camera connected via USB. I can get access to target camera's unique_id, and also other infos provided by AVFoundation. But I don't know how to locate my target USB device to send a UVC ControlRequest. There's many Cameras with same VendorID and ProductID connected at a time, so I need a more exact way to find out which device is my target. It looks that the unique_id provided is (locationID<<32|VendorID<<16|ProductID) as hex string, but I'm not sure if I can always assume this behavior won't change. Is there's a document declares how AVFoundation generate the unique_id for USB camera, so I can assume this convert will always work? Or is there's a way to send a PTZ control request to AVCaptureDevice? https://stackoverflow.com/questions/40006908/usb-interface-of-an-avcapturedevice I have seen this similar question. But I'm worrying that Exacting LocationID+VendorID+ProductID from unique_id seems like programming to implementation instead of interface. So, if there's any other better way to control my camera? here's my example code for getting unique_id: // // camera_unique_id_test.mm // // 测试代码：使用C++获取当前系统摄像头的AVCaptureDevice unique_id // // 编译命令: // clang++ -framework AVFoundation -framework CoreMedia -framework Foundation // camera_unique_id_test.mm -o camera_unique_id_test // #include <iostream> #include <string> #include <vector> #import <AVFoundation/AVFoundation.h> #import <Foundation/Foundation.h> struct CameraInfo { std::string uniqueId; }; std::vector<CameraInfo> getAllCameraDevices() { std::vector<CameraInfo> cameras; @autoreleasepool { NSArray<AVCaptureDevice*>* devices = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo]; AVCaptureDevice* defaultDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; // 遍历所有设备 for (AVCaptureDevice* device in devices) { CameraInfo info; // 获取unique_id info.uniqueId = std::string([device.uniqueID UTF8String]); cameras.push_back(info); } } return cameras; } int main(int argc, char* argv[]) { std::vector<CameraInfo> cameras = getAllCameraDevices(); for (size_t i = 0; i < cameras.size(); i++) { const CameraInfo& camera = cameras[i]; std::cout << " 设备 " << (i + 1) << ":" << std::endl; std::cout << " unique_id: " << camera.uniqueId << std::endl; } return 0; } and here's my code for UVC control: // clang++ -framework Foundation -framework IOKit uvc_test.cpp -o uvc_test #include <iostream> #include <CoreFoundation/CoreFoundation.h> #include <IOKit/IOCFPlugIn.h> #include <IOKit/IOKitLib.h> #include <IOKit/IOMessage.h> #include <IOKit/usb/IOUSBLib.h> #include <IOKit/usb/USB.h> CFStringRef CreateCFStringFromIORegistryKey(io_service_t ioService, const char* key) { CFStringRef keyString = CFStringCreateWithCString(kCFAllocatorDefault, key, kCFStringEncodingUTF8); if (!keyString) return nullptr; CFStringRef result = static_cast<CFStringRef>( IORegistryEntryCreateCFProperty(ioService, keyString, kCFAllocatorDefault, kIORegistryIterateRecursively)); CFRelease(keyString); return result; } std::string GetStringFromIORegistry(io_service_t ioService, const char* key) { CFStringRef cfString = CreateCFStringFromIORegistryKey(ioService, key); if (!cfString) return ""; char buffer[256]; Boolean success = CFStringGetCString(cfString, buffer, sizeof(buffer), kCFStringEncodingUTF8); CFRelease(cfString); return success ?

Fundamentally, my questions are: is there a known transform I can apply onto a given (pixel) position (passed into a Metal Fragment Function) to correctly sample a texture provided by the main cameras + processed by a Vision request. If so, what is it? If not, how can I accurately sample my masks? My goal is to highlight people in a Vision Pro app using Compositor Services. To start, I asynchronously receive camera frames for the main left and right cameras. This is the breakdown of the specific CameraVideoFormat I pass along to the CameraFrameProvider: minFrameDuration: 0.03 maxFrameDuration: 0.033333335 frameSize: (1920.0, 1080.0) pixelFormat: 875704422 cameraType: main cameraPositions: [left, right] cameraRectification: mono From each camera frame sample, I extract the left and right buffers (CVReadOnlyPixelBuffer.withUnsafebuffer ==> CVPixelBuffer). I asynchronously process the extracted buffers by performing a VNGeneratePersonSegmentationRequest on both of them: // NOTE: This block of code and all following code blocks contain simplified representations of my code for clarity's sake. var request = VNGeneratePersonSegmentationRequest() request.qualityLevel = .balanced request.outputPixelFormat = kCVPixelFormatType_OneComponent8 ... let lHandler = VNSequenceRequestHandler() let rHandler = VNSequenceRequestHandler() ... func processBuffers() async { try lHandler.perform([request], on: lBuffer) guard let lMask = request.results?.first?.pixelBuffer else {...} try rHandler.perform([request], on: rBuffer) guard let rMask = request.results?.first?.pixelBuffer else {...} appModel.latestPersonMasks = (lMask, rMask) } I store the two resulting CVPixelBuffers in my appModel. For both of these buffers aka grayscale masks: width (in pixels) = 512 height (in pixels) = 384 byters per row = 512 plane count = 0 pixel format type = 1278226488 I am using Compositor Services to render my content in Immersive Space. My implementation of Compositor Services is based off of the same code from Interacting with virtual content blended with passthrough. Within the Shaders.metal, the tint's Fragment Shader is now passed the grayscale masks (converted from CVPixelBuffer to MTLTexture via CVMetalTextureCacheCreateTextureFromImage() at the beginning of the main render pipeline). fragment float4 tintFragmentShader( TintInOut in [[stage_in]], ushort amp_id [[amplification_id]], texture2d<uint> leftMask [[texture(0)]], texture2d<uint> rightMask [[texture(1)]] ) { if (in.color.a <= 0.0) { discard_fragment(); } float2 uv; if (amp_id == 0) { // LEFT uv = ??????????????????????; } else { // RIGHT uv = ??????????????????????; } constexpr sampler linearSampler (mip_filter::linear, mag_filter::linear, min_filter::linear); // Sample the PersonSegmentation grayscale mask float maskValue = 0.0; if (amp_id == 0) { // LEFT if (leftMask.get_width() > 0) { maskValue = rightMask.sample(linearSampler, uv).r; } } else { // RIGHT if (rightMask.get_width() > 0) { maskValue = rightMask.sample(linearSampler, uv).r; } } if (maskValue > 250) { return (1.0, 1.0, 1.0, 0.5) } return in.color; } I need to correctly sample the masks for a given fragment. The LayerRenderer.Layout is set to .layered. From Developer Documentation. A layout that specifies each view’s content as a slice of a single texture. Using the Metal debugger, I know that the final render target texture for each view / eye is 1888 x 1792 pixels, giving an aspect ratio of 59:56. The initial CVPixelBuffer provided by the main left and right cameras is 1920x1080 (16:9). The grayscale CVPixelBuffer returned by the VNPersonSegmentationRequest is 512x384 (4:3). All of these aspect ratios are different. My questions come down to: is there a known transform I can apply onto a given (pixel) position to correctly sample a texture provided by the main cameras + processed by a Vision request. If so, what is it? If not, how can I accurately sample my masks? Within the tint's Vertex Shader, after applying the modelViewProjectionMatrix, I have tried every version I have been able to find that takes the pixel space position (= vertices[vertexID].position.xy) and the viewport size (1888x1792) to compute the correct clip space position (maybe = pixel space position.xy / (viewport size * 0.5)???) of the grayscale masks but nothing has worked. The "highlight" of the person segmentations is off: scaled a little too big, offset little to far up and off to the side.

The iPhone 17’s front camera with the new 18MP square sensor and iOS 26’s Center Stage feature can auto-rotate between portrait and landscape like the native iOS Camera app. Is there a Swift or AVFoundation API that allows developers to manually control front camera orientation in the same way the native Camera app does? Or is this auto-rotation strictly handled by the system without public API access?

Hi, I'm a fan of the gallery in vision pro which has video as well as still photography but I'm wondering if Apple has considered adding the projected media tags to heic so that we can go that next step from Spatial photos to Immersive photos. I have a device that can give me 12k x 6k fisheye images in HDR, but it can't do it at a framerate or resolution that's good enough for video, so I want to cut my losses and show off immersive photos instead. Is there something Apple is already working on for APMP stills or should I create my own app that reads metadata inside a HEIC that I infer in a similar way to the demo "ProjectedMediaConversion" is doing for Video. It would be great to have 180VR photos, which could show as Spatial in a gallery view, but going immersive would half-surround you instead of floating in the blurred view. I think that would be a pretty amazing effect.

In what scenario will an app receive the limitExceeded PHPhotosError code? This case was added in iOS 26.1 and is not currently documented. What PhotoKit APIs can encounter this error and how should it be handled?

Problem Description (1) I am using ARKit in an iOS app to provide AR capabilities. Specifically, I'm trying to use the ARSession's captureHighResolutionFrame(using:) method to capture a high-resolution frame along with its corresponding depth data: open func captureHighResolutionFrame(using photoSettings: AVCapturePhotoSettings?) async throws -> ARFrame (2) However, when I attempt to do so, the call fails at runtime with the following error, which I captured from the Xcode debugger: [AVCapturePhotoOutput capturePhotoWithSettings:delegate:] settings.depthDataDeliveryEnabled must be NO if self.isDepthDataDeliveryEnabled is NO Code Snippet Explanation (1) ARConfig and ARSession Initialization The following code configures the ARConfiguration and ARSession. A key part of this setup is setting the videoFormat to the one recommended for high-resolution frame capturing, as suggested by the documentation. func start(imagesDirectory: URL, configuration: Configuration = Configuration()) { // ... basic setup ... let arConfig = ARWorldTrackingConfiguration() arConfig.planeDetection = [.horizontal, .vertical] // Enable various frame semantics for depth and segmentation if ARWorldTrackingConfiguration.supportsFrameSemantics(.smoothedSceneDepth) { arConfig.frameSemantics.insert(.smoothedSceneDepth) } if ARWorldTrackingConfiguration.supportsFrameSemantics(.sceneDepth) { arConfig.frameSemantics.insert(.sceneDepth) } if ARWorldTrackingConfiguration.supportsFrameSemantics(.personSegmentationWithDepth) { arConfig.frameSemantics.insert(.personSegmentationWithDepth) } // Set the recommended video format for high-resolution captures if let videoFormat = ARWorldTrackingConfiguration.recommendedVideoFormatForHighResolutionFrameCapturing { arConfig.videoFormat = videoFormat print("Enabled: High-Resolution Frame Capturing by selecting recommended video format.") } arSession.run(arConfig, options: [.resetTracking, .removeExistingAnchors]) // ... } (2) Capturing the High-Resolution Frame The code below is intended to manually trigger the capture of a high-resolution frame. The goal is to obtain both a high-resolution color image and its associated high-resolution depth data. To achieve this, I explicitly set the isDepthDataDeliveryEnabled property of the AVCapturePhotoSettings object to true. func requestImageCapture() async { // ... guard statements ... print("Manual image capture requested.") if #available(iOS 16.0, *) { // Assuming 16.0+ for this API if let defaultSettings = arSession.configuration?.videoFormat.defaultPhotoSettings { // Create a mutable copy from the default settings, as recommended let photoSettings = AVCapturePhotoSettings(from: defaultSettings) // Explicitly enable depth data delivery for this capture request photoSettings.isDepthDataDeliveryEnabled = true do { let highResFrame = try await arSession.captureHighResolutionFrame(using: photoSettings) print("Successfully captured a high-resolution frame.") if let initialDepthData = highResFrame.capturedDepthData { // Process depth data... } else { print("High-resolution frame was captured, but it contains no depth data.") } } catch { // The exception is caught here print("Error capturing high-resolution frame: \(error.localizedDescription)") } } } // ... } Issue Confirmation & Question (1) Through debugging, I have confirmed the following behavior: If I call captureHighResolutionFrame without providing the photoSettings parameter, or if photoSettings.isDepthDataDeliveryEnabled is set to false, the method successfully returns a high-resolution ARFrame, but its capturedDepthData is nil. (2) The error message clearly indicates that settings.depthDataDeliveryEnabled can only be true if the underlying AVCapturePhotoOutput instance's own isDepthDataDeliveryEnabled property is also true. (3) However, within the context of ARKit and ARSession, I cannot find any public API that would allow me to explicitly access and configure the underlying AVCapturePhotoOutput instance that ARSession manages. (4) My question is: Is there a way to configure the ARSession's internal AVCapturePhotoOutput to enable its isDepthDataDeliveryEnabled property? Or, is simultaneously capturing a high-resolution frame and its associated depth data simply not a supported use case in the current ARKit framework?

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() } }

In my app, I use api provided in Photos framework to delete specified photo. But after upgrading to iOS 26, the delete function in some iOS device no longer work. The api will never triggers the system confirmation dialog, and the completionHandler is never called. In the iOS Photos app, deletion works correctly on the same assets, but calling the API from my app does not work. Steps to Reproduce Make sure the app has Full Photo Library Access. Execute the following code: PHPhotoLibrary.shared().performChanges({ let assetsToBeDeleted = PHAsset.fetchAssets(withLocalIdentifiers: delUrls, options: nil) PHAssetChangeRequest.deleteAssets(assetsToBeDeleted) }, completionHandler: completionHandler) Expected Behavior The system should present a confirmation dialog asking the user to delete the selected photos. After the user confirms, the deletion should occur, and the completionHandler should be called with success or error. Actual Behavior The system delete confirmation dialog does not appear. The completionHandler is never called. Environment iOS Versions: 26.1 / 26.0.1 It looks like api bug. I want to check Is it a know issue and will be fixed. Thanks

If the app is launched from LockedCameraCapture and if the settings button is tapped, I need to launch the main app. CameraViewController: func settingsButtonTapped() { #if isLockedCameraCaptureExtension //App is launched from Lock Screen //Launch main app here... #else //App is launched from Home Screen self.showSettings(animated: true) #endif } In this document: https://developer.apple.com/documentation/lockedcameracapture/creating-a-camera-experience-for-the-lock-screen Apple asks you to use: func launchApp(with session: LockedCameraCaptureSession, info: String) { Task { do { let activity = NSUserActivityTypeLockedCameraCapture activity.userInfo = [UserInfoKey: info] try await session.openApplication(for: activity) } catch { StatusManager.displayError("Unable to open app - \(error.localizedDescription)") } } } However, the documentation states that this should be placed within the extension code - LockedCameraCapture. If I do that, how can I call that all the way down from the main app's CameraViewController?

On iOS 26.1, this throws on the 2020 iPad Pro (4th gen) but works fine on an M4 iPad Pro or iPhone 15 Pro: guard let device = AVCaptureDevice.default(.builtInLiDARDepthCamera, for: .video, position: .back) else { throw ConfigurationError.lidarDeviceUnavailable } It's just the standard code from Apple's own sample code so obviously used to work: https://developer.apple.com/documentation/AVFoundation/capturing-depth-using-the-lidar-camera Does it fail because Apple have silently dumped support for the older LiDAR sensor used prior to the M4 iPad Pro, or is there another reason? What about the 5th and 6th gen iPad Pro, does it still work on those?

we are working on HDR images and found this problem, asset.mediaSubtypes.contains(.photoHDR) always return false func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { guard !results.isEmpty else {return} let fetchResult = PHAsset.fetchAssets(withLocalIdentifiers: results.map({$0.assetIdentifier!}), options: nil) var selectedAssets:[PHAsset] = [] fetchResult.enumerateObjects { asset, _, _ in selectedAssets.append(asset) } for i in selectedAssets.enumerated() { let asset:PHAsset = i.element print("\(i.offset): ") print(PHAssetMediaSubtype.photoHDR.rawValue) print(asset.mediaSubtypes) print("photoHDR \(PHAssetMediaSubtype.photoHDR.rawValue): \(asset.mediaSubtypes.contains(.photoHDR))") print("photoLive \(PHAssetMediaSubtype.photoLive.rawValue): \(asset.mediaSubtypes.contains(.photoLive))") print("photoPanorama \(PHAssetMediaSubtype.photoPanorama.rawValue): \(asset.mediaSubtypes.contains(.photoPanorama))") print("photoScreenshot \(PHAssetMediaSubtype.photoScreenshot.rawValue): \(asset.mediaSubtypes.contains(.photoScreenshot))") print("videoHighFrameRate \(PHAssetMediaSubtype.videoHighFrameRate.rawValue): \(asset.mediaSubtypes.contains(.videoHighFrameRate))") print("videoScreenRecording \(PHAssetMediaSubtype.videoScreenRecording.rawValue): \(asset.mediaSubtypes.contains(.videoScreenRecording))") } }

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)"

The introduction of PHBackgroundResourceUploadExtension is a welcome addition in iOS 26.1. I wonder however, how to attach a debugger and actually get the system to call the process() method of the extension. I tried to run the extension both inside photos app (and also the main app for testing), but when I take a photo or add photos to the library (saving), the process() method does never get called. Any hints would be appreciated to debug the PHBackgroundResourceUploadExtension during development.

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?

Hi, I’m trying to implement the new PhotoKit PHBackgroundResourceUploadExtension. I created the extension, enabled full photo library access in the host app, and registered the extension point using the string: com.apple.photos.background-upload. However, when I attempted to enable the extension with: try library.setUploadJobExtensionEnabled(true) I received the following error: Error Domain=PHPhotosErrorDomain Code=-1 "(null)" This happens when running the app on Xcode 26.1 and 26.2 Beta, using the iPhone 17 Pro Max simulator (iOS 26.1 and 26.2). My question is: Is this extension supported on the simulator? I’m asking because at the moment it’s difficult for me to test this on a physical device. Also, What's the meaning of the error? Thanks.

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?
