The documentation for this API mentions: The system uses the current representation and avoids transcoding, if possible. What are the scenarios in which transcoding takes place? The reason for asking is that we've had a user reaching out saying they selected a video file from their Photos app, which resulted in a decrease in size from ~110MB to 35MB. We find it unlikely it's transcoding-related, but we want to gain more insights into the possible scenarios.

I am able to detect screenshot only after screenshot is taken. UIApplication.userDidTakeScreenshotNotification. But my requirement is to detect at the same time while user is taking screenshot, so that I can hide my confidential data. Please comment out if there are any better solutions or any callback functions available.

Hello, is it possible to reference a photo from the photo picker (either UIKit or SwiftUI), such that I do not need to copy it somewhere else? Currently, I am storing the copy in CoreData in a field with external storage, but it did cross my mind that I don't actually need a copy in my own storage if I could point back to the photo library. If the user deleted the photo from the library that would be fine.

Currently, PhotosPickerItem cannot be used from async/await code safely, for example in Tasks etc., because it does not conform to Sendable. The public api has only two properties, both of which are of a Sendable type: UTType and String?. Is this something that's going to be changed so I can mark it as @unchecked Sendable in my code, or is there an actual underlying reason why PhotosPickerItem is not Sendable? PHAsset, PHAssetCollection, PHFetchRequest, PHObject are all sendable, because - similarly to PhotosPickerItem - they contain no actual image data, they are just a preliminary representation of an image in the Photos app.

It is 2023 and Photos.app still provides no way to sort photos/movies by file size. I ended up writing some AppleScript that displays the file sizes of images/movies in a specific album. It is also simple to create a shell script to examine the photo library contents directly but mapping the UUID-based filenames back to the names used in Photos.app is not straightforward (to me at least). You can't even create a smart album based upon file size. Why is there no native support for this in Photos.app/PhotoKit? (And, yes, I have submitted many feature requests over the years)

I know that I can uniquely identify a PHAsset on a given device using localIdentifier but if that asset is synched (through iCloud, say) to another device, how to I uniquely identify that asset across multiple devices? My app allows users to store their images in the standard photo gallery, but I have no way of referring to them when they sync their app profile to another iOS device with my app installed.

I use loadFileRepresentation to register video URL. After that, loadItem will take less time to see the video from the picker. But after upgrade Iphone to 16.6, this func can not work. Have any change or dev team removed loadItem it? Here is my sample code: provider.loadItem(forTypeIdentifier: "public.movie", options: nil) { url, error in guard let url = url as? URL else { return } self.parent.selectedVideoURL = url // Check cached, if loadFileRepresentation before use url from loadItem more faster let storage = LocalStorageHelper() if storage.checkStringExistStorage(MEDIA_PICKER_STORAGE_NAMESPACE, url.relativeString) { DispatchQueue.main.async { self.parent.presentationMode.wrappedValue.dismiss() self.parent.videoURL = url } } else { provider.loadFileRepresentation(forTypeIdentifier: "public.movie") { urlResult, error in DispatchQueue.main.async { self.parent.presentationMode.wrappedValue.dismiss() } if let error = error { // Handle errors loading video LOGGING.error("Error loading video: \(error.localizedDescription)") return } guard let urlFile = urlResult else {return} // create a new filename let fileName = "\(Int(Date().timeIntervalSince1970)).\(urlFile.pathExtension)" // create new URL let newUrl = URL(fileURLWithPath: NSTemporaryDirectory() + fileName) // copy item to APP Storage try? FileManager.default.copyItem(at: urlFile, to: newUrl) DispatchQueue.main.async { storage.saveStringToStorage(MEDIA_PICKER_STORAGE_NAMESPACE, url.relativeString) self.parent.videoURL = URL(string: newUrl.absoluteString) } } } }

I'm working with Apple's sample code for PhotoBrowse. In the main view controller's viewDidLoad() method we have this code: let allPhotosOptions = PHFetchOptions() allPhotosOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: true)] This code sorts the photos by "creationDate". How do I determine/find the other valid values for these sort descriptors? For example, what if I wanted to sort photos by their file size, last modified date, etc.? TIA!

In my app I get a UIImage for a PHAsset via PHImageManager.requestImage(for:targetSize:contentMode:options:resultHandler:). I directly display that image in a UIImageView that has preferredImageDynamicRange set to .high. The problem is I do not see the high dynamic range. I see the HDRDemo23 sample code uses PhotosPicker to get a UIImage from Data through UIImageReader whose config enables prefersHighDynamicRange. Is there a way to support HDR when using the Photos APIs to request display images? And is there support for PHLivePhoto displayed in PHLivePhotoView retrieved via PHImageManager.requestLivePhoto?

I have a safari webkit inside my mobile app which renders a webpage. The webpage has File upload option. when I click on it 3 options are shown as in screenshot. I am trying to make the safari kit to only allow Camera capture and hide Upload already existing files.  Is there any safari permission which I can remove to configuration that hide the options of upload from files.

Using the new inline PhotosPicker style in iOS 17, it isn't made clear how to handle the cancel button's input, and i cannot seem to find an answer in the documentation. PhotosPicker( "Select picture", selection: $selected, selectionBehavior: .default, photoLibrary: .shared() ) .photosPickerStyle(.inline) Does anybody have a solution or is this a bug that needs to be fixed?

Dear Experts, PHAsset.creationDate is an NSDate, which does not have a timezone associated with it, right? Consider a photo viewer app. If I take a photo of the sunrise at 0600 local time while I am away, when I get home and view the photo in the app, I believe I want the timestamp shown with the photo to be 0600. Do you agree? But NSDate is just a time-point, and I don't think Foundation (or anything else in iOS) has a type that combines a time-point with a time zone. Nor does PHAsset have any other useful attributes - unless I were to determine the time zone from the location! Am I missing anything?

Users can run our apps on Macs with Apple Silicon via the "iPad Apps on Mac" feature. The apps use PHPhotoLibrary.requestAuthorization(for: .addOnly, handler: callback) to request write-only access to the user's Photo Library during image export. This works as intended on macOS, but a huge problem arises when the user denies access (by accident or intentionally) and later decides that they want us to add their image to Photos: There is no way to grant this permission again. In System Preferences → Privacy & Security → Photos, the app is just not listed – in fact, none of the "iPad Apps on Mac" apps appear here. Not even tccutil reset all my.bundle.id works. It just reports tccutil: Failed to reset all approval status for my.bundle.id. Uninstalling, restarting the Mac, and reinstalling the app also doesn't work. The system seems to remember the initial decision. Is this an oversight in the integration of those apps with macOS, or are we missing something fundamental here? Is there maybe a way to prompt the user again?

Hello, In one of my apps, I'm trying to modify the pixel buffer from a ProRAW capture to then write the modified DNG. This is what I try to do: After capturing a ProRAW photo, I work in the delegate function func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) { ... } In here I can access the photo.pixelBuffer and get its base address: guard let buffer = photo.pixelBuffer else { return } CVPixelBufferLockBaseAddress(buffer, []) let pixelFormat = CVPixelBufferGetPixelFormatType(buffer) // I check that the pixel format corresponds with ProRAW . This is successful, the code enters the if block if (pixelFormat == kCVPixelFormatType_64RGBALE) { guard let pointer = CVPixelBufferGetBaseAddress(buffer) else { return } // We have 16bits per component, 4 components let count = CVPixelBufferGetWidth(buffer) * CVPixelBufferGetHeight(buffer) * 4 let mutable = pointer.bindMemory(to: UInt16.self, capacity: count) // As a test, I want to replace all pixels with 65000 to get a white image let finalBufferArray : [Float] = Array.init(repeating: 65000, count: count) vDSP_vfixu16(finalBufferArray, 1, mutable, 1, vDSP_Length(finalBufferArray.count)) // I create an vImage Pixel buffer. Note that I'm referencing the photo.pixelBuffer to be sure that I modified the underlying pixelBuffer of the AVCapturePhoto object let imageBuffer = vImage.PixelBuffer<vImage.Interleaved16Ux4>(referencing: photo.pixelBuffer!, planeIndex: 0) // Inspect the CGImage let cgImageFormat = vImage_CGImageFormat(bitsPerComponent: 16, bitsPerPixel: 64, colorSpace: CGColorSpace(name: CGColorSpace.displayP3)!, bitmapInfo: CGBitmapInfo(rawValue: CGImageAlphaInfo.last.rawValue | CGBitmapInfo.byteOrder16Little.rawValue))! let cgImage = imageBuffer.makeCGImage(cgImageFormat: cgImageFormat)! // I send the CGImage to the main view controller. This is successful, I can see a white image when rendering the CGImage into a UIImage. This lets me think that I successfully modified the photo.pixelBuffer firingFrameDelegate?.didSendCGImage(image: cgImage) } // Now I try to write data. Unfortunately, this does not work. The photo.fileDataRepresentation() writes the data corresponding to the original, unmodified pixelBuffer `if let photoData = photo.fileDataRepresentation() { // Sending the data to the view controller and rendering it in the UIImage displays the original photo, not the modified pixelBuffer firingFrameDelegate?.didSendData(data: photoData) thisPhotoData = photoData }` CVPixelBufferUnlockBaseAddress(buffer, []) The same happens if I try to write the data to disk. The DNG file displays the original photo and not the data corresponding to the modified photo.pixelBuffer. Do you know why this code should not work? Do you have any ideas on how I can modify the ProRAW pixel buffer so that I can write the modified buffer into a DNG file? My goal is to write a modified file, so, I'm not sure I can use CoreImage of vImage to output a ProRAW file.

We observed that the PHPicker is unable to load RAW images captured on an iPhone in some scenarios. And it is also somehow related to iCloud. Here is the setup: The PHPickerViewController is configured with preferredAssetRepresentationMode = .current to avoid transcoding. The image is loaded from the item provider like this: if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage) { itemProvider.loadFileRepresentation(forTypeIdentifier: kUTTypeImage) { url, error in // work } } This usually works, also for RAW images. However, when trying to load a RAW image that has just been captured with the iPhone, the loading fails with the following errors on the console: [claims] 43A5D3B2-84CD-488D-B9E4-19F9ED5F39EB grantAccessClaim reply is an error: Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application."

We think it is related to iCloud Photos: On the device that has iCloud Photos sync enabled, the picker is able to load the image right after it was synced to the cloud. On devices that don't sync the image, loading always fails. It seems that the sync process is doing some processing (?) of the image that will later enable the picker to load it successfully, but that's just guessing. Additional observations: This seems to only occur for images that were taken with the stock Camera app. When using Halide to capture RAW (either ProRAW or RAW), the Picker is able to load the image. When trying to load the image as kUTTypeRawImage instead of kUTTypeImage, it also fails. The picker also can't load RAW images that were AirDroped from another device, unless it synced to iCloud first. This is reproducable using the Selecting Photos and Videos in iOS sample code project. We observed this happening in other apps that use the PHPicker, not just ours. Is this a bug, or is there something that we are missing?

I  am trying to save an image to the user's photo library using PHPhotoLibrary and set the image file name at the time of saving suing the code below. This is working the first time, but if I then try to save the same image again with a different file name, it saves with the same file name as before. Is there something I need to add to let the system know to save a new version of the image with a new file name? Thank you PHPhotoLibrary.shared().performChanges ({ let assetType:PHAssetResourceType = .photo let request:PHAssetCreationRequest = .forAsset() let createOptions:PHAssetResourceCreationOptions = PHAssetResourceCreationOptions() createOptions.originalFilename = "\(fileName)" request.addResource(with: assetType, data: image.jpegData(compressionQuality: 1)!, options: createOptions) }, completionHandler: { success, error in if success == true && error == nil { print("Success saving image") } else { print("Error saving image: \(error!.localizedDescription)") } })

Environment: iOS 16 beta 2, beta 3. iPhone 11 Pro, 12 mini Steps to reproduce: Subscribe to Photo Library changes via PHPhotoLibraryChangeObserver, put some logs to track inserted/deleted objects: func photoLibraryDidChange(_ changeInstance: PHChange) { if let changeDetails = changes.changeDetails(for: allPhotosFetchResult) { for insertion in changeDetails.insertedObjects { print("🥶 INSERTED: ", insertion.localIdentifier) } for deletion in changeDetails.removedObjects { print("🥶 DELETED: ", deletion.localIdentifier) } } } Save a photo to camera roll with PHAssetCreationRequest Go to the Photo Library, delete the newly saved photo Come back to the app and watch the logs: 🥶 INSERTED:  903933C3-7B83-4212-8DF1-37C2AD3A923D/L0/001 🥶 DELETED:  39F673E7-C5AC-422C-8BAA-1BF865120BBF/L0/001 Expected result: localIdentifier of the saved and deleted asset is the same string in both logs. In fact: It's different. So it appears that either the localIdentifier of an asset gets changed after successful saving, or it's a bug in the Photos framework in iOS 16. I've checked - in iOS 15 it works fine (IDs in logs match).

While trying to save a photo to a custom album on some devices we get the following error: The operation couldn’t be completed. (PHPhotosErrorDomain error 3300). code: 3300 This is the part of the code where the issue happens PHPhotoLibrary.shared().performChanges({ let assetChangeRequest = PHAssetChangeRequest.creationRequestForAsset(from: image) guard let placeholder = assetChangeRequest.placeholderForCreatedAsset else { return } let albumChangeRequest = PHAssetCollectionChangeRequest(for: album) albumChangeRequest?.addAssets([placeholder] as NSArray) }, completionHandler: { success, error in completion(success, error) }) I would be thankful for any tips since I am out of ideas.

For PHPickerViewController, we know we can perform simple filtering by var config = PHPickerConfiguration() config.filter = PHPickerFilter.images But, how about we only want to show images with format JPG & PNG, but excluding GIF? This is because our app doesn't support GIF. Is it possible to do so?
