I have an iOS app that includes a Photo Editing Extension and is optimized for Mac Catalyst so you can edit photos in the Photos app on your Mac. This has worked really well but now I am encountering an error alert trying to open the photo editing extension: RBSLaunchRequest error trying to launch plugin com.company.TestEditor.

As the image access policy has changed with Android targeting SDK 34, I’m planning to update the way our app accesses photos. We are using the react-native-image-picker library to access images. On Android, the system no longer prompts the user for image access permissions, but on iOS, permission requests still appear. Since Android no longer requires explicit permissions, I’ve removed the permission request logic for Android. In this case, is it also safe to remove the permission request for iOS? In our app, photo access is only used for changing the user profile picture and attaching images when writing a post on the bulletin board. Are there any limitations or considerations for this kind of usage?

Hi all, In MacOS, how can I disable or enable build-in camera by program or script?

Has Objective-C been deprecated?

A functioning Multiplatform app, which includes use of Continuity Camera on an M1MacMini running Sequoia 15.5, works correctly capturing photos with AVCapturePhoto. However, that app (and a test app just for Continuity Camera) crashes at delegate callback when run on a 2017 MacBookPro under MacOS 13.7.5. The app was created with Xcode 16 (various releases) and using Swift 6 (but tried with 5). Compiling and running the test app with Xcode 15.2 on the 13.7.5 machine also crashes at delegate callback. The iPhone 15 Continuity Camera gets detected and set up correctly, and preview video works correctly. It's when the CapturePhoto code is run that the crash occurs. The relevant capture code is: func capturePhoto() { let captureSettings = AVCapturePhotoSettings() captureSettings.flashMode = .auto photoOutput.maxPhotoQualityPrioritization = .quality photoOutput.capturePhoto(with: captureSettings, delegate: PhotoDelegate.shared) print("**** CameraManager: capturePhoto") } and the delegate callbacks are: class PhotoDelegate: NSObject, AVCapturePhotoCaptureDelegate { nonisolated(unsafe) static let shared = PhotoDelegate() // MARK: - Delegate callbacks func photoOutput( _ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)? ) { print("**** CameraManager: didFinishProcessingPhoto") guard let pData = photo.fileDataRepresentation() else { print("**** photoOutput is empty") return } print("**** photoOutput data is \(pData.count) bytes") } func photoOutput( _ output: AVCapturePhotoOutput, willBeginCaptureFor resolvedSettings: AVCaptureResolvedPhotoSettings ) { print("**** CameraManager: willBeginCaptureFor") } func photoOutput(_ output: AVCapturePhotoOutput, willCapturePhotoFor resolvedSettings: AVCaptureResolvedPhotoSettings) { print("**** CameraManager: willCaptureCapturePhotoFor") } } The crash report significant parts are.....

Hello! In iOS1.7.5, photogrammetry sessions cannot be performed on iPhones without LiDAR, but I don't think there is much difference in GPU performance between those with and without LiDAR. For example, the chips installed in the iPhone 14 Pro and iPhone 15 are the same A16 Bionic, and I think the GPU performance is also the same. Despite this, photogrammetry can be performed on the iPhone 14 Pro but not on the iPhone 15. Why is this? In fact, we have confirmed that if you transfer images taken with an iPhone 16 without LiDAR to an iPhone 16 Pro and run a photogrammetry session using those images, a 3D model can be generated. Also, will photogrammetry be able to be performed on high-performance iPhones without LiDAR in the future?

I'm developing a tennis ball tracking feature using Vision Framework in Swift, specifically utilizing VNDetectedObjectObservation and VNTrackObjectRequest. Occasionally (but not always), I receive the following runtime error: Failed to perform SequenceRequest: Error Domain=com.apple.Vision Code=9 "Internal error: unexpected tracked object bounding box size" UserInfo={NSLocalizedDescription=Internal error: unexpected tracked object bounding box size} From my investigation, I suspect the issue arises when the bounding box from the initial observation (VNDetectedObjectObservation) is too small. However, Apple's documentation doesn't clearly define the minimum bounding box size that's considered valid by VNTrackObjectRequest. Could someone clarify: What is the minimum acceptable bounding box width and height (normalized) that Vision Framework's VNTrackObjectRequest expects? Is there any recommended practice or official guidance for bounding box size validation before creating a tracking request? This information would be extremely helpful to reliably avoid this internal error. Thank you!

Hello everyone, I am looking for a solution to programmatically, e.g. using AppleScript to import photos into the Photos library on MacOS and also push them to the shared library, like it can be done using the standard GUI of the Photos application. Maybe it is not possible using AppleScript, but using a short Swift script and PhotoKit, I do not not know. Any help is appreciated! Thomas

when I get results from picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) and I load the image using itemProvider .loadFileRepresentation (the itemProvider is the NSItemProvider provided by the PHPickerResult) will the url that's returned by this method be guaranteed to have the file extension ie, "file://image.jpeg" not "file://image" I want to know if i need to just check the extension to know its file type. (FYI in case this makes a difference, im only interested in user screenshots and screenrecordings)

I am developing a video streaming app for iPhone. Minimum version is IOS 13. I want to connect an external USB camera to the iPhone app and stream from it. I have looked through a lot of information and have not found how to do this. Is it possible to do this? Is there any documentation on this?

I found that when the development tool above Xcode16 ran my app, I opened the suspended inscription function, and then opened the system camera, the content in the suspended window would not be displayed, and the suspended window would have a black screen. However, this phenomenon does not appear on Xcode15.4 development tools, it is the same code, I do not know why

On some devices, when i select the same media multiple times, the data by` loadFileRepresentation(forTypeIdentifier: completionHandler) ` returned is different(data.count is not equal). environment: * Model: iPhone 12 * Model Number: MGGM3CH/A * iOS Version: 18.3.2 ```Swift // import PhotosUI func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { picker.dismiss(animated: true, completion: nil) guard let provider = results.last?.itemProvider else { return } guard provider.hasItemConformingToTypeIdentifier(UTType.movie.identifier) else { return } Task { provider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { url, error in guard let url = url else { return } if let data = try? Data(contentsOf: url) { print("data count is: \(data.count)") } } } } ``` ps: I also try some other function, eg: ` provide.loadItem(forTypeIdentifier:)`, but not work too.

On some devices, loadFileRepresentation(forTypeIdentifier: completionHandler) take a loong time(about two minute) to callback result for some large video(about 200 MB, take by device camera). environment: Model: iPhone 12 Model Number: MGGM3CH/A iOS Version: 18.3.2 PHPickerResult.NSItemProvider.loadFileRepresentation() // import PhotosUI func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { picker.dismiss(animated: true, completion: nil) guard let provider = results.last?.itemProvider else { return } guard provider.hasItemConformingToTypeIdentifier(UTType.movie.identifier) else { return } Task { provider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { url, error in guard let url = url else { return } // Do some stuff... } } } ps: I also try some other function, eg: provide.loadItem(forTypeIdentifier:), but not work too.

Hi all, I'm using Apple Sample Code below to create application using dockkit. "Controlling a DockKit accessory using your camera app" https://developer.apple.com/documentation/dockkit/controlling-a-dockkit-accessory-using-your-camera-app?changes=_8 I used vision hand recognition and put the observation data to dockAccessory.track, but Belkin or Insta360 devices never move on iPhone 16 Pro Max with iOS 18.3. If I use other functions like face search (system tracking) in the app, those work ok. I used Belkin and Insta360 Flow 2 Pro to reproduce the problem. My friend is also saying that the custom tracking feature was working fine on the OS 18 beta, but on recent iOS 18.3 that feature does not work. If I can get the iOS 18.0 beta then we can test that feature. But I cannot revert my iOS from 18.3 to the iOS 18.0 Beta. Regards, TO

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?

I am working on an iOS application using SwiftUI where I want to convert a JPG and a MOV file to a live photo. I am utilizing the LivePhoto Class from Github for this. The JPG and MOV files are displayed correctly in my WallpaperDetailView, but I am facing issues when trying to download the live photo to the gallery and generate the Live Photo.
