I'm new here so I don't know what's this function belongs to which topic... Sorry about that!
I watched the WWDC stream and I am really interested in this function, I'm wondering if this function could be used in my apps.
I looked up the document but I find it only support visionOS(i'm not sure about that, but I saw the demo is base on the visionOS)

Hi I am trying to implement something simple as people can share their Spatial Photos with others (just like this post). I encountered the same issue with him, but his answer doesn't help me out here.
Briefly speaking, I am using CGImgaeSoruce to extract paired leftImage and rightImage from one fetched spatial photo
let photos = PHAsset.fetchAssets(with: .image, options: nil)
// enumerating photos ....
if asset.mediaSubtypes.contains(PHAssetMediaSubtype.spatialMedia) {
spatialAsset = asset
}
// other code show below
I can fetch left and right images from native Spatial Photo (taken by Apple Vision Pro or iPhone 15+), but it didn't work on generated spatial photo (2D -> 3D feat in Photos).
// imageCount is 1 when it comes to generated spatial photo
let imageCount = CGImageSourceGetCount(source)
I searched over the net and someone says the generated version is having a depth image instead of left/right pair. But still I cannot extract any depth image from imageSource.
The full code below, the imagePair extraction will stop at "no groups found":
func extractPairedImage(phAsset: PHAsset, completion: @escaping (StereoImagePair?) -> Void) {
let options = PHImageRequestOptions()
options.isNetworkAccessAllowed = true
options.deliveryMode = .highQualityFormat
options.resizeMode = .none
options.version = .original
return PHImageManager.default().requestImageDataAndOrientation(for: phAsset, options: options) {
imageData, _, _, _ in
guard let imageData,
let imageSource = CGImageSourceCreateWithData(imageData as CFData, nil)
else {
completion(nil)
return
}
let stereoImagePair = stereoImagePair(from: imageSource)
completion(stereoImagePair)
}
}
}
func stereoImagePair(from source: CGImageSource) -> StereoImagePair? {
guard let properties = CGImageSourceCopyProperties(source, nil) as? [CFString: Any] else {
return nil
}
let imageCount = CGImageSourceGetCount(source)
print(String(format: "%d images found", imageCount))
guard let groups = properties[kCGImagePropertyGroups] as? [[CFString: Any]] else {
/// function returns here
print("no groups found")
return nil
}
guard
let stereoGroup = groups.first(where: {
let groupType = $0[kCGImagePropertyGroupType] as! CFString
return groupType == kCGImagePropertyGroupTypeStereoPair
})
else {
return nil
}
guard let leftIndex = stereoGroup[kCGImagePropertyGroupImageIndexLeft] as? Int,
let rightIndex = stereoGroup[kCGImagePropertyGroupImageIndexRight] as? Int,
let leftImage = CGImageSourceCreateImageAtIndex(source, leftIndex, nil),
let rightImage = CGImageSourceCreateImageAtIndex(source, rightIndex, nil),
let leftProperties = CGImageSourceCopyPropertiesAtIndex(source, leftIndex, nil),
let rightProperties = CGImageSourceCopyPropertiesAtIndex(source, rightIndex, nil)
else {
return nil
}
return (leftImage, rightImage, self.identifier)
}
Any suggestion? Thanks

How do I test the new RecognizeDocumentRequest API. Reference: https://www.youtube.com/watch?v=H-GCNsXdKzM
I am running Xcode Beta, however I only have one primary device that I cannot install beta software on.
Please provide a strategy for testing. Will simulator work?
The new capability is critical to my application, just what I need for structuring document scans and extraction.
Thank you.
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 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. TestPhotoEditor (B7A616A7-2 5A8-4E02-8B32-5CAB37C8B4B2): ErrorDomain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x7f08fafd0 {ErrorDomain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}
Create a new iOS app project in Xcode
Create a new target and choose iOS > Photo Editing Extension
For both targets in the project, add Mac Catalyst as a supported destination
Run the app on My Mac (Mac Catalyst)
Open the Photos app, double click a photo, click Edit, click the more plugins button, and click TestPhotoEditor in the list

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!

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.
Here is the relevant code and the errors I am encountering:
Console prints:
Play button should be visible Image URL fetched and set: Optional("https://firebasestorage.googleapis.com/...") Video is ready to play Video downloaded to: file:///var/mobile/Containers/Data/Application/.../tmp/CFNetworkDownload_7rW5ny.tmp Failed to generate Live Photo
I have verified that the app has the necessary permissions to access the Photo Library.
The JPEG and MOV files are successfully downloaded and can be displayed in the app.
The issue seems to occur when generating the Live Photo from the downloaded files.

Hello everyone,
I’m working on an iOS app that fetches videos from the "Recently Deleted" album using the Photos framework in Swift. However, I’m unable to fetch any videos, even though the "Recently Deleted" album contains 233 items (including videos), as seen in the Photos app.
Environment:
iOS Version: 18.3.1
Xcode Version: 16.2
Swift Version: Swift 5
Device: iPhone (simulator and physical device both tested)
Photo Library Permission: "All Photos" access granted
Recently Deleted Lock: Face ID/Passcode is disabled for "Recently Deleted"
I want to create a Live Photo. The project includes a .jpg image and a .mov video (2 seconds). I am sure they are correct.
Two permissions in xcode have been added:
Privacy - Photo Library Usage Description
Privacy - Photo Library Additions Usage Description Simulate: iphone 16, ios 18.3
The codes in ContentView.swift :
private func saveLivePhoto(imageURL: URL, videoURL: URL, completion: @escaping (Bool, Error?) -> Void) {
PHPhotoLibrary.shared().performChanges {
let creationRequest = PHAssetCreationRequest.forAsset()
let options = PHAssetResourceCreationOptions()
options.shouldMoveFile = false
creationRequest.addResource(with: .photo, fileURL: imageURL, options: options)
creationRequest.addResource(with: .pairedVideo, fileURL: videoURL, options: options)
} completionHandler: { success, error in
DispatchQueue.main.async {
print(error)
completion(success, error)
}
}
}
guard let imageURL = Bundle.main.url(forResource: "livephoto", withExtension: "jpeg"),
let videoURL = Bundle.main.url(forResource: "livephoto", withExtension: "mov") else {
showAlertMessage(title: "error", message: "cant find Live Photo ")
return
}
print("imageURL: \(imageURL)")
print("videoURL: \(videoURL)")
saveLivePhoto(imageURL: imageURL, videoURL: videoURL) { success, error in
if success {
xxxxx
} else {
xxxxx
}
}
Really need help, thanks

According to the docs:
The first time your app performs an operation that requires [photo library] authorization, the system automatically and asynchronously prompts the user for it.
(https://developer.apple.com/documentation/photokit/delivering-an-enhanced-privacy-experience-in-your-photos-app)
I.e. it's not necessary for the app to call PHPhotoLibrary.requestAuthorization.
This does seem to be what happens when my app runs on an iPhone or iPad; the prompt is shown. But when it runs on a Mac in "designed for iPad" mode, the permission dialog is not presented. Instead the code continues to see status == .notDetermined.
That's today, on macOS 15.3. It may have worked in the past.
Is anyone else seeing issues with this? Should I call requestAuthorization explicitly? (Would that actually work?)
Hello, I'm wondering how to capture 24MP photos.
I'm currently testing on an iPhone 16 Pro Max. By default, the device's activeFormat supports 24MP (photo dimensions: {4032x3024, 5712x4284}). For the photoOutput, I'm setting the maxPhotoDimensions to videoDevice.activeFormat.supportedMaxPhotoDimensions.lastObject, and setting MaxPhotoQualityPrioritization to quality.
When capturing, I'm applying the same maxPhotoDimensions and photoQualityPrioritization settings from the photoOutput directly to the AVCapturePhotoSettings.
What could be the issue?
// Objective-C
// setup
[self.photoOutput setMaxPhotoQualityPrioritization:AVCapturePhotoQualityPrioritizationQuality];
CMVideoDimensions maxPhotoDimensions = [(NSValue *)videoDevice.activeFormat.supportedMaxPhotoDimensions.lastObject CMVideoDimensionsValue];
[self.photoOutput setMaxPhotoDimensions:maxPhotoDimensions];
// capturing
AVCapturePhotoSettings *photoSettings = [AVCapturePhotoSettings photoSettings];
photoSettings.maxPhotoDimensions = self.photoOutput.maxPhotoDimensions;
photoSettings.photoQualityPrioritization = self.photoOutput.maxPhotoQualityPrioritization;
[self.photoOutput capturePhotoWithSettings:photoSettings delegate:photoCaptureDelegate];
...
Hey,
I have a camera app that captures a ProRaw photo and then runs a few Core Image filters before saving it to the device as a HEIC. However I'm finding that capturing at 48MP is rather slow. Testing a minimal pipeline on an iPhone 16 Pro:
Shutter press => file received in output: 1.2 ~ 1.6s
CIRawFilter created using photo file representation then rendered to context, without any filters: 0.8s ~ 1s
Saving to device ~0.15s
Is this the expected time for capturing processing? The native camera app seems to save the images within half a second. I'm using QualityPrioritization.balanced and the highest resolution available which is 48MP.
Would using the CIRawFilter with the pixelBuffer from the photo output be faster? I tried it but couldn't get it to output an image. Are there any other things I could try to speed this up? Is it possible to capture at 24MP instead?
Thanks,
Alex
iOS 18.4 - iPhone 14 Pro Max - open a photo with a face - click on info button and there is no face icon. Also there is no option to add a name to a face. Restart of iPhone didn’t help. Also this small icon of recognized face that should be on each photo with a face- disappeared from old photos.
Hi,
I'm using Core Graphics to load a .DNG photo shot by a Leica Q3 camera.
The photo is shot in portrait, however the embedded preview is rotated 90 degrees to landscape.
I load the photo like this:
let options = [kCGImageSourceDecodeRequest: kCGImageSourceDecodeToHDR] as CFDictionary
let source = CGImageSourceCreateWithData(data as CFData, nil)
let cgimage = CGImageSourceCreateImageAtIndex(source, 0, options)
let properties = CGImageSourceCopyPropertiesAtIndex(source, 0, nil) as? [CFString : Any]
When doing this I can see that the orientation property is 1 indicating that the orientation is 'Up', which it isn't.
If I don't specify the kCGImageSourceDecodeToHDR option (eseentially setting options to nil) - the orientation property is 8 (rotated 90 degrees).
What puzzles me is that a chang to the CGImageSourceCreateImageAtIndex call can have an influence on that latter call to CGImageSourceCopyPropertiesAtIndex ?
I would expect these to work independently?
Cheers
Thomas
I want to modify the photo's exif information, which means putting the original image in through CGImageDestinationAddImageFromSource, and then adding the modified exif information to a place called properties.
Here is the complete process:
static func setImageMetadata(asset: PHAsset, exif: [String: Any]) {
let options = PHContentEditingInputRequestOptions()
options.canHandleAdjustmentData = { (adjustmentData) -> Bool in
return true
}
asset.requestContentEditingInput(with: options, completionHandler: { input, map in
guard let inputNN = input else {
return
}
guard let url = inputNN.fullSizeImageURL else {
return
}
let output = PHContentEditingOutput(contentEditingInput: inputNN)
let adjustmentData = PHAdjustmentData(formatIdentifier: AppInfo.appBundleId(), formatVersion: AppInfo.appVersion(), data: Data())
output.adjustmentData = adjustmentData
let outputURL = output.renderedContentURL
guard let source = CGImageSourceCreateWithURL(url as CFURL, nil) else {
return
}
guard let dest = CGImageDestinationCreateWithURL(outputURL as CFURL, UTType.jpeg.identifier as CFString, 1, nil) else {
return
}
CGImageDestinationAddImageFromSource(dest, source, 0, exif as CFDictionary)
let d = CGImageDestinationFinalize(dest)
// d is true, and I checked the content of outputURL, image has been write correctly, it could be convert to UIImage and image is ok.
PHPhotoLibrary.shared().performChanges {
let changeReq = PHAssetChangeRequest(for: asset)
changeReq.contentEditingOutput = output
} completionHandler: { succ, err in
if !succ {
print(err) // 3303 here, always!
}
}
})
}
I am trying to recreate the iOS Messages app photo selection UI, where a PHPickerViewController is displayed half screen, with the message text field and a scrolling photo viewer on top. I have that UI mostly working, but cannot figure out how to allow a user to remove an image from my scrolling photo viewer (just like in the iOS Messages app).
When the picker is initially displayed, I can show selected images using the preselectedAssetIdentifiers. However, if the user taps the "x" to remove an image from the scrolling photo viewer, there is no way that I have found to update that selection in the picker.
I can dismiss/show a new picker with the animated property set to false, but that creates a very apparent bounce in the screen. Are there any ways I am missing to accomplish this?
Here is what I have so far:
Is there a suitable
UTType type to satisfy the need to pick up only SpatialVideo in UIDocumentPickerViewController?
I already know that PHPickerFilter in PHPickerViewController can do this, but not in UIDocumentPickerViewController.
Our app needs to adapt both of these ways to pick spatial videos
So is there anything that I can try in UIDocumentPickerViewController to fulfill such picker functionality?

I'm getting the following error in my SwiftUI code:
"Main actor-isolated property 'avatarImage' can not be referenced from a Sendable closure"
I don't understand how to fix it.

When picking a photo in the gallery, whatever the orientation of the original image, size is always as landscape
if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.editedImage)] as? UIImage {
print("picked original", image.size)
For a portrait photo:
picked original (1122.0, 932.0)
For a landscape:
picked original (1124.0, 844.0)
What am I missing ?
