We are using inline PhotosPicker introduced with iOS 17.0. The accessbility navigation using touch gestures work fine but the navigation through Keyboard doesn't work properly. The tab/arrow based Keyboard navigation can't move from native app process to inline PhotosUI process or vice versa. This is logged as a high severity bug by our accessibility team. Please look into this. Sample code for repro: https://github.com/saalisumer/AccessibilityIssueInlinePhotoPickerIOS Repro video: https://github.com/saalisumer/AccessibilityIssueInlinePhotoPickerIOS/blob/main/Simulator%20Screen%20Recording%20-%20iPhone%2015%20Pro%20-%202024-12-16%20at%2016.27.48.mp4

Hello Our application is backing up the user photos to some back end. When retrieving the asset data from the Photo Library, we set the flag 'accessNetworkAllowed' to true to get the assets that might be optimized in iCloud. In the application logs, we can see the message below, and it shows as coming from com.apple.photos.backend (PhotoKit) Missing prefetched properties for PHAssetAdjustmentProperties on <PHAsset: 0x160b1ec00> BCF5688F-F7A7-4196-AFC7-A84E8BD95F3E/L0/001 mediaType=1/0, sourceType=1, (5601x3734), creationDate=2022-01-24 23:36:05 +0000, location=0, hidden=0, favorite=0, adjusted=0 . Fetching on demand on the main queue, which may degrade performance. In particular, the message says 'Fetching on demand on the main queue' but I'm not sure if that means that PhotoKit will fetch on main queue or if that mean that our application is requesting the data on main queue. Anyone could clarify? thanks

Hello, I m trying to implement deferred photo processing in my photo capture app. After I take a photo, I pass it through a CIFilter, now with the Deferred Photo Processing where would I pass the resulting photo through the CIFilter? Since there is no way for me to know when the system has finished processing a photo. If I have to do it in my app foreground every time, how do I prevent a scenario, where the user takes a photo, heads straight to the Photos App and sees the image without the filter?

Hi, I'm having difficulties figuring out how I can reliably detect if the macOS system PHPhotoLibrary is available. If I place the system Photo Library on an external drive and then eject it, other apps on startup, such as Photos, will tell me that the library isn't available. How can I replicate this behavior? The only API I can find for this detection on startup is "PHPhotoLibrary.shared().unavailabilityReason". However this always returns nil. Another strange behavior is if I register a PHPhotoLibraryAvailabilityObserver class on startup when the library is available and then eject the drive, I do get a notification via photoLibraryDidBecomeUnavailable, but then directly after the call the app is terminated. This prevents the app to perform any kind of graceful termination. Is this the expected behavior? It would make sense that it's up to the developer to decide what happens if the library becomes unavailable. Thanks

When trying to edit some Live Photos, calling PHLivePhotoEditingContext.saveLivePhoto results in the following error: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-12815), NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x300d05380 {Error Domain=NSOSStatusErrorDomain Code=-12815 "(null)"}} I was able to replicate it on my device by taking a new Live Photo. Not sure what's wrong with that one specifically, not all Live Photos replicate the issue. I've submitted FB15880825 with a sysdiagnose and a Photos Diagnostics as well. Any ideas what's going on here? It's impacting multiple customers. Thanks!

I have an app that allows the user to change a photo’s EXIF metadata. To do this, I request a content editing input, get the full size image, modify its properties, create a content editing output, write the output image to the rendered content URL, then call performChanges on the PHPhotoLibrary creating an asset change request for that asset setting its content editing output. This works as expected for regular photos but Live Photos get turned off converted to a regular photo. To address this, I’m doing something similar by changing the properties of the .photo image in the Live Photo. I detect when the content editing input has a Live Photo, create a Live Photo editing context, set a frame processor that returns the frame’s image after setting its properties to the updated properties when the frame type is photo, then I create the content editing output and save the Live Photo to that output. It modifies the Live Photo successfully, but the metadata is not updated. If you get the full size image again the properties are the original properties. If you look at the EXIF metadata using an app like Metapho it remains unchanged. What am I doing wrong here? Thanks! let imageURL = contentEditingInput.fullSizeImageURL! let inputImage = CIImage(contentsOf: imageURL, options: [.applyOrientationProperty: true])! var metadata: [AnyHashable: Any] = inputImage.properties // Edit the metadata as desired... let editingContext = PHLivePhotoEditingContext(livePhotoEditingInput: contentEditingInput)! editingContext.frameProcessor = { frame, error -> CIImage? in // Edit only the still photo if frame.type == .photo { return frame.image.settingProperties(metadata) } return frame.image } let contentEditingOutput = try await withCheckedThrowingContinuation { continuation in let editingOutput = PHContentEditingOutput(contentEditingInput: contentEditingInput) editingOutput.adjustmentData = adjustmentData editingContext.saveLivePhoto(to: editingOutput) { success, error in if success { continuation.resume(returning: editingOutput) } else { continuation.resume(throwing: error!) } } } try await PHPhotoLibrary.shared().performChanges { let request = PHAssetChangeRequest(for: asset) request.contentEditingOutput = contentEditingOutput }

Hi fellow iOS developers! 👋 I've written a Swift code that converts a video (from a URL) into a Live Photo after downloading it. The conversion process seems fine, but when I try to set the generated Live Photo as a wallpaper on iOS 17+, it shows the message 'Motion not Available.' Has anyone else experienced this issue or know why this might be happening? Could it be related to changes in iOS 17 Live Photo handling or the generated file structure? Any help or suggestions would be greatly appreciated! 🙏

I tried several times to use the PhotosPickerItem loadTransferable function with the goal of receiving some progress value especially when loading large video media. However, the Progress object returned by the function has always isIndeterminate == true and so doesn't have any progress value to observe. Is there some way to make it work ? Some configuration I might have overlooked ? Or is it just not working I might have to revert back to the UIKit photo picker because of this

Hello! I am trying to remove a photo from my Photos Library using PhotosUI. I run into this error when I attempt to delete it: "Error returned from daemon: Error Domain=com.apple.accounts Code=7 "(null)"" No photos access scope requirements declared for changes Failed to log access with error: access= accessor:<> identifier:82068C12-FD10-4DE2-9867-B4406FBFB706 kind:intervalEvent timestampAdjustment:0 visibilityState:0 assetIdentifierCount:0 accessCount:0 tccService:kTCCServicePhotos, error=Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.privacyaccountingd" UserInfo={NSDebugDescription=connection to service named com.apple.privacyaccountingd}

While customizing ImagePicker and using it, we find out that the metadata is not reflected normally and report it. The situation is as follows. The time or time zone of an image is changed in the Photos app. Changing the time zone of an image with an actual capture date of 2024:11:08 08:27:44 → 2024:11:07 17:27:44 Image data is extracted from a PHAsset using PHImageManager. The metadata is obtained from this image data. The time zone information exposed in the Exif tag information does not reflect the time or time zone changed in the Photos app. let asset: PHAsset = ... .... let options = PHImageRequestOptions() options.isSynchronous = true options.version = .current options.deliveryMode = .highQualityFormat options.resizeMode = .none options.normalizedCropRect = .zero options.isNetworkAccessAllowed = true options.progressHandler = { progress, error, _, _ in } PHImageManager.default().requestImageDataAndOrientation(for: asset, options: options) { imageData, uti, orientation, info in let cgImageSource = CGImageSourceCreateWithData(imageData! as CFData, nil) let properties = CGImageSourceCopyPropertiesAtIndex(cgImageSource!, 0, nil) as? Dictionary&lt;String, Any&gt; let exif = properties!["{Exif}"] let dictionary = exif as? Dictionary&lt;String, Any&gt; } Metadata Check In this case, it is reflected in the creationDate of PHAsset, so it can be somewhat compensated by forcibly replacing the metadata. However, because PHAsset does not include time zone information, when changing the time zone as well, it's impossible to calculate the correct time according to the time zone. PHPicker This issue is resolved when using the PHPickerResult provided by PHPicker. extension PhotosPickerViewController: PHPickerViewControllerDelegate { public func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { ..... for result in results { let identifier = UTType.image.identifier if result.itemProvider.hasItemConformingToTypeIdentifier(identifier) { result.itemProvider.loadDataRepresentation(forTypeIdentifier: identifier) { data, error in guard let data = data, let cgImageSource = CGImageSourceCreateWithData(data as CFData, nil), let properties = CGImageSourceCopyPropertiesAtIndex(cgImageSource, 0, nil) as? Dictionary&lt;String, Any&gt;, let exif = properties["{Exif}"], let dictionary = exif as? Dictionary&lt;String, Any&gt; else { return } } } } } } Metadata Check Question I wonder why this happens, and if this is normal behavior. Instead of the System Picker that Apple provides as a base, I wonder if there is any way I can supplement it in that situation if I use a customizer.

iOS (Official) Photos app can display some EXIF-related metadata (e.g. camera and lens info, ISO, shutter speed, F-number) even when photos are offloaded to iCloud and the device is not connected to internet (e.g. airplane mode). However, with the Photos.framework, we need to download photos to retrive those metadata (which means it will not work with airplane mode). I tried the following methods, but none of those worked when photos were offloaded to iCloud and the device was in airplane mode: Requesting data with PHImageManager.default().requestImageDataAndOrientation Result: It does not return Data if the photo is not stored locally on the device, even with options.deliveryMode = .fastFormat Converting PHAsset#localIdentifier to an AssetsLibrary.framework URL (assets-library://asset/...) (I am aware that AssetsLibrary.framework is deprecated, but this was just a test.) Result: If PHImageManager does not returns Data, ALAsset#defaultRepresentation().metadata() returns an empty NSDictionary

I have an app that allows you to edit your photos. To preserve HDR, I edit both the SDR image and gain map image, like so: let sdrImage = CIImage(data: data, options: [.applyOrientationProperty: true]) let gainMapImage = CIImage(data: data, options: [.applyOrientationProperty: true, .auxiliaryHDRGainMap: true]) // edit them... try CIContext().writeHEIFRepresentation(of: sdrImage, to: url, format: .RGBA8, colorSpace: colorSpace, options: [.hdrGainMapImage: gainMapImage]) I also support editing the still photo in Live Photos. To do this you create a PHLivePhotoEditingContext, set the frameProcessor block which gives you a CIImage that I edit when the frame.type is .photo, then you create a PHContentEditingOutput and call saveLivePhoto. I’m not seeing any way to preserve HDR here. Interestingly the frame processor is called twice with .photo frame.type, but I don’t see any difference between these images. How can I edit a gain map image to preserve HDR in the still photo of a Live Photo?

I've requested the authentication in my main app. PHPhotoLibrary.requestAuthorization(for: .readWrite) { status in } Add the privacy description in both the main app and the extension. But No matter the device is locked or unlocked. When I call let fetchResult = PHAsset.fetchAssets(with: .image, options: nil) let count = fetchResult.count the count is always zero, even after a new photo is saved to the album in the same session.

I have an app that edits photos in your library. When I call try CIContext().writeHEIFRepresentation(of: editedImage, to: fileURL, format: .RGBA8, colorSpace: originalImage.colorSpace!) The following is logged to the console: writeImageAtIndex:1012: ⭕️ ERROR: 'App' is trying to save an opaque image (5712x4284) with 'AlphaLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. What does that mean and how can I resolve it?

We are currently in the process of migrating our application from using ALAssetsLibrary to PHPhotoLibrary to ensure compatibility with the latest versions of iOS. However, we have noticed a discrepancy in the file sizes of images obtained using PHPhotoLibrary compared to those obtained using ALAssetsLibrary. Specifically, we would like to understand the following points: 1.Reason for File Size Differences: What are the reasons for the difference in file sizes between images obtained using ALAssetsLibrary and those obtained using PHPhotoLibrary? Could you provide detailed information on the settings and options in PHPhotoLibrary that affect the size and quality of the images? 2.Optimal Settings: What are the optimal settings in PHPhotoLibrary to obtain images with the same quality and file size as those obtained using ALAssetsLibrary? If possible, could you provide code examples or recommended option settings?

I have noticed a problem when a PHAsset creation request is made with the resource type PHAssetResourceType.photoProxy. let creationRequest = PHAssetCreationRequest.forAsset() creationRequest.addResource(with: .photoProxy, data: photoData, options: nil) creationRequest.location = location creationRequest.isFavorite = true After successfully saving the resulting asset through PHPhotoLibrary.shared().performChanges, I could verify it in the Photos app. I noticed that the created photo was initially marked as Favorite and that the location was added to the info as expected. The title of the image changes from "Today" to "" too. Next, the photo was refreshed, and location data was purged. However, the title remains unchanged and displays the . This refresh was also observed in the code. PHPhotoLibraryChangeObserver protocols func photoLibraryDidChange(_ changeInstance: PHChange) receives a change notification. The same asset has been changed, and there is no location information anymore. isFavorite information persists correctly. After debugging for a few hours, I discovered that changing the resource type to .photo fixes this issue. Location data is not removed in the Photos app, and no refresh callback is seen in func photoLibraryDidChange(_ changeInstance: PHChange). I initially used .photoProxy because in the AVCapturePhotoCaptureDelegate implementation class, I always get the call in func photoOutput(_ output: AVCapturePhotoOutput, didFinishCapturingDeferredPhotoProxy deferredPhotoProxy: AVCaptureDeferredPhotoProxy?, error: Error?). So here is where I am capturing the photo data as photoData = deferredPhotoProxy?.fileDataRepresentation().

Hello, I’ve encountered an issue where a green line appears only in the thumbnail view of an image in the iPhone photo gallery. The green line is not present in the actual image itself. Here are some additional details: • The issue occurs only when saving the image as a JPEG. When saved as PNG, the green line does not appear. • The green line also shows up when using the PHAsset method requestImage(for:targetSize:). Depending on the targetSize, the resulting image may contain the green line. • Interestingly, this issue does not appear on iPhone Xs Max running iOS 15.2.1. However, the green line does appear on iPhone 15 Pro Max running iOS 18.0.1 when viewing the same image. I have attached the problematic image for your reference. Following images are the screen captures that shows the issue occurring on my iPhone. iPhone 15 pro max (iOS 18.0.1) iPhone Xs Max (iOS 15.2.1 ) Could this be related to a display or gallery app issue on iOS? Any advice or solutions would be greatly appreciated. Thank you!

A very common use case in our iOS app is that users take a large number of pictures (about 30) in low-light conditions using the camera app, and immediately after, they try to upload them to our servers. We measured the time to load photos from the PHPickerResult. For most photos, it takes less than 100 milliseconds, but for some of them, it takes several seconds—we even saw minutes in some extreme cases. We believe this started happening with iOS 17, when deferred photo processing was introduced. If users take the pictures using our in-app camera experience, the options to customize the camera are enough to avoid the long waiting times. However, the majority of our users still prefer to take the photos with the camera app, and there is little we can do about that. In the past few weeks, we tried many combinations: Without asking for permissions, we tried loadFileRepresentation, loadData, and loadObject. We explored the PHImageManager route, asking permissions and with different options for deliveryMode, resizeMode, version, isSynchronous, and allowSecondaryDegradedImage. We also tried fetching the photos in parallel, with very bad results. In summary, nothing helped the long waiting times—minutes in some cases. The first question is then, is there anything we can do to ignore the post-processing of the photos and get them fast? We could accept the unprocessed images. At a minimum, we would like to show our users what we are doing and why we are taking so much time. We tried to load thumbnails with loadPreviewImage and put a progress indicator on top. This method consistently gives us an error for all photos: (lldb) p error.localizedDescription (String) "Cannot load preview." We can load thumbnails with the PHImageManager option, but it seems excessive to need to get permissions only for that. Second question would be then, what can we do to load thumbnails without asking for permission? I created a feedback report with a video and sample code to reproduce -> FB15493683

I'm using PhotoKit in macOS to add photos to the user's library. Experimenting with Shared Photo Library, it seems that these new photos always end up in the Personal Library, not the Shared Library. I'd like to get them into the Shared Photo Library somehow. Is this possible? Things I've considered: A variation/option for PHAssetChangeRequest.creationRequestForAsset: doesn't seem to exist A property of PHAsset: can't find anything A special PHAssetCollection that I could add to: again, doesn't seem to exist

Hello developer community. I purchase recently my new iPhone 16 Pro Max; it is a premium device with great quality overall. However, I am having a big trouble shotting in ProRaw MAX (48 mode) with native camera. Just to be clear, the problem that i will describe do not happen in 3rd apps, such as ProCam; only with native camera. When I use ProRaw Max, and take the photo, and watch the photo in the gallery the image can’t load and render properly. Even, when I maximize the image to the maximum I can see pixelated portions, defects and super low resolution and excessive denoise. For comparison, this not occur with my previous iPhone 15 PM and/or when I capture photos from ProCam (same settings and configurations) in the 16PM. I proceed to take the photo, open the gallery and I see full of details, when zoomed to 100%. I tried to format the phone, reinstall the software via my mac. Tried even to look at some forums to find if there’s someone with the same issue, the information available so far is very low. I’m in contact with apple assistant from my country (Portugal), and they escalated this problem to the engineers. (that’s what I’ve been told). They did all the tests remotely (via analysis and improvement’s) and they told me that my phone is perfect in the hardware department. I will wait for the next days to be contacted again. I’m on iOS 18.0.1. (The last software available at this time). I tried multiple 16PM, from friends, family and stores (more or less 10 units), and they all showed the exact same problematic. I’m a professional photographer, so I find this frustrating and unacceptable. I would appreciate any additional suggestion or information. Thank you! Cannot add photos or files because they are bigger than 5Mb.
