I'm working on an application that uses the iPhone camera for scientific purposes - and, as a result would like to receive sensor data in as unprocessed format as possible. I'm using AVCapturePhotoOutput to take Bayer RAW stills and receiving data in kCVPixelFormatType_14Bayer_RGGB format. However, I'm puzzled as to the content of the bits. I simply demosaic the image by taking each 2x2 square: RG GB and use R, (G+G)/2, B to get 16-bit RGB values - and this indeed works. However, I am puzzled as to the values we are getting as they seem to be approximately in the range 2048 - 16383. The top value is understandable - the maximum that you can fit in 14-bits (as implied by the pixel format type). However we don't seem to be able to get lower than ~2048 no matter how black/dark we make the sensor. I'm aware that the sensor is probably not 14-bits (we're using the iPhone 16e camera) and that maybe this is to do with the way the sensor data is packaged. The Advances in iOS Photography video (https://developer.apple.com/videos/play/wwdc2016/501/) describes it as "10-bit sensor RAW packaged in 14 bits per pixel instead of eight." Is there any documentation describing what is going on here? It's vital for our use that we get as close to the raw camera sensor light readings as possible, so any pointers as to the mapping (e.g. decompanding?) being used would be extremely useful. Many thanks in advance for your help.

My app is a camera app that supports Picture-in-Picture (PiP) mode. Normally, when the device rotates, I get the device orientation from iOS and use it to rotate the camera feed so that the preview stays correctly aligned. However, when the app enters PiP mode, it is considered to be in the background, and I can no longer receive orientation updates from the system. As a result, I can’t apply rotation corrections to the camera video in PiP mode. Is there any way to retrieve device orientation while the app is in the background (specifically during PiP mode)? Any guidance would be greatly appreciated. Thank you!

In the AVP project, a selector pops up, only wanting to filter spatial videos. When selecting the material of one of the spatial videos, the selection result returns empty. How can we obtain the video selected by the user and get the path and the URL of the file The code is as follows： PhotosPicker(selection: $selectedItem, matching: .videos) { Text("Choose a spatial photo or video") } func loadTransferable(from imageSelection: PhotosPickerItem) -> Progress { return imageSelection.loadTransferable(type: URL.self) { result in DispatchQueue.main.async { // guard imageSelection == self.imageSelection else { return } print("加载成功的图片集合:(result)") switch result { case .success(let url?): self.selectSpatialVideoURL = url print("获取视频链接:(url)") case .success(nil): break // Handle the success case with an empty value. case .failure(let error): print("spatial错误：(error)") // Handle the failure case with the provided error. } } } }

I am seeing a crash on iOS 18.0 in my app due to PHImageManager.default().requestImage. Same crash is seen even while using requestImageDataAndOrientation. Not sure why this is happening only on iOS 18.0. Any help on this would be appreciated.

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?

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.
