When selecting more photos with previous limited authorization, I get this crash on iOS 17.0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PHPhotoLibrary presentLimitedLibraryPickerFromViewController:completionHandler:]: unrecognized selector sent to instance 0x105ea2a60'
when using the synchronous and asynchronous methods:
PHPhotoLibrary.shared().presentLimitedLibraryPicker(from: viewController) { newlySelectedPhotoIDs in ...
OR
let newlySelectedPhotoIDs = await PHPhotoLibrary.shared().presentLimitedLibraryPicker(from: viewController)
Debugger output is unexpected... after all these methods are in the header...
(lldb) po PHPhotoLibrary.shared().responds(to: #selector(PHPhotoLibrary.presentLimitedLibraryPicker(from:)))
false
(lldb) po PHPhotoLibrary.shared().responds(to: #selector(PHPhotoLibrary.presentLimitedLibraryPicker(from:completionHandler:)))
false
I have been searching high and low for anyone that has encountered the same issue,
My problem is when an image is not actually on the device but rather in iCloud, my app fails to retrieve the image. How would i go about remedying this?
My code for PHPicker implementation is as follows, any help would be greatly appreciated.
extension PageViewController: PHPickerViewControllerDelegate {
func presentPicker() {
ArtModel.holdingBay.removeAll()
var configuration = PHPickerConfiguration()
configuration.filter = .images
configuration.selectionLimit = 5
let picker = PHPickerViewController(configuration: configuration)
picker.delegate = self
present(picker, animated: true)
}
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
if results.count 0 {
for result in results {
result.itemProvider.loadObject(ofClass: UIImage.self, completionHandler: { (object, error) in
if let image = object as? UIImage {
DispatchQueue.main.async {
ArtModel.holdingBay.append(image)
}
}
})
}
}
picker.dismiss(animated: true, completion: self.holdingBayCheck)
}
func holdingBayCheck() {
if ArtModel.holdingBay.count 0 {
performSegue(withIdentifier: K.goToCrop, sender: self)
}
}
}
I'm trying to provide a mechanism for the user to select a bg image from their photo library. I've got this code which theoretically is getting the data but can't figure out how to convert it to an Image in SwiftUI. I've found plenty of examples on iOS but none workable on MacOS.
This is my implementation of the PhotosPicker on iOS:
PhotosPicker(selection: $vm.selectedBGphoto, matching: .images) {
Label("Select Background Image", systemImage: "photo.on.rectangle")
}
.tint(.purple)
.controlSize(.large)
.onChange(of: vm.selectedBGphoto) { newItem in
Task {
if let data = try? await newItem?.loadTransferable(type: Data.self) {
if let uiImage = UIImage(data: data) {
vm.selectedBGdata = data
vm.bgImage = Image(uiImage: uiImage)
}
}
}
This DOES NOT work on MacOS because of the UIImage reference. How do I convert what I get from PhotosPicker into an Image on MacOS?

Now I use AVFoundation framework to get the photo output, but the image aspect ratio is 4:3. But according to the Camera app in the iPhone 13 Pro, it has server image aspect ratio: 4:3, 16:9 and 1:1 when take the proraw image. So how can I get the 1:1, 16:9 aspect ratio proraw image?
After I do some research, I find that no matter you use which kinds of camera in the iPhone 11, 12, 13, 14, 15 or Pro, the result image is always 4:3, 1:1 and 16:9 come from the 4:3 cropping. If it is true, how can I crop the proraw file without any data lossing?

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.

In iOS 17.0.3, photos taken using Apple's native camera app can't be loaded immediately (within approximately 30 seconds) through PHPickerViewController. Specifically, the method itemProvider.canLoadObject(ofClass: UIImage.self) returns false. However, after about 30 seconds post-capture, the photos load without any hindrance.
Initially, I considered an issue with my own photo-loading code, but the same problem persists even with Apple's official PHPickerDemo sample code.
[PHPickerDemo - SelectingPhotosAndVideosInIOS.zip]
https://developer.apple.com/documentation/photokit/selecting_photos_and_videos_in_ios
ViewController.swift Line 89 (PHPickerDemo)
func displayNext() {
guard let assetIdentifier = selectedAssetIdentifierIterator?.next() else { return }
currentAssetIdentifier = assetIdentifier
let progress: Progress?
let itemProvider = selection[assetIdentifier]!.itemProvider
if itemProvider.canLoadObject(ofClass: PHLivePhoto.self) {
progress = itemProvider.loadObject(ofClass: PHLivePhoto.self) { [weak self] livePhoto, error in
DispatchQueue.main.async {
self?.handleCompletion(assetIdentifier: assetIdentifier, object: livePhoto, error: error)
}
}
}
else if itemProvider.canLoadObject(ofClass: UIImage.self) { <========================================= FALSE
progress = itemProvider.loadObject(ofClass: UIImage.self) { [weak self] image, error in
DispatchQueue.main.async {
self?.handleCompletion(assetIdentifier: assetIdentifier, object: image, error: error)
}
}
}
...omitted...
}
Environment & Settings:
iPhone 12
iOS 17.0.3
Settings -> Camera -> Formats -> High Efficiency (Enabled)
Reproduction Steps:
Take a photo in normal photo mode with Apple's native camera app (not in portrait mode).
Launch the PHPickerDemo app.
Tap the photo icon located in the top right.
Observe that the photo fails to load.
Workarounds:
Wait for over 30 seconds prior to selecting the photo.
Opt to shoot in portrait mode rather than the standard photo mode.
Switch on Settings -> Camera -> Formats -> Most Compatible.
I am developing a photo editing app, and I have received many emails from users stating that they cannot select photos since updating to iOS 17.
Thanks.

I have a UICollectionView to display photos from a device's album with the Photos framework. The photos are correctly displayed, but if I scroll fast (like when you tape at the top of the screen to go to the top of the collectionView), I have some photos which are not at the good indexPath. I just need to scroll a bit to put the bad photo out of the screen, and everything go back in place.I clean the cell during prepareForReuse by canceling the current request.I presume it's a problem with the asynchronous request of PHImageManager, but I don't know how to avoid this problem. And I want to keet the asynchronous request to keep the collectionView smooth.Here some code :View Controller extension AlbumDetailViewController : UICollectionViewDataSource {
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return photoList.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("PhotoCell", forIndexPath: indexPath) as! PhotoCollectionCell
cell.setImage(photoList.objectAtIndex(indexPath.row) as! PHAsset)
return cell
}
}Custom CollectionViewCell class PhotoCollectionCell: UICollectionViewCell {
@IBOutlet weak var imageView: UIImageView!
var requestId: PHImageRequestID!
let manager = PHImageManager.defaultManager()
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func prepareForReuse() {
self.imageView.image = nil
manager.cancelImageRequest(self.requestId)
}
func setImage(asset: PHAsset) {
let option = PHImageRequestOptions()
option.resizeMode = .Fast
option.deliveryMode = .HighQualityFormat
self.requestId = manager.requestImageForAsset(asset, targetSize: CGSize(width: self.frame.size.width * UIScreen.mainScreen().scale, height: self.frame.size.height * UIScreen.mainScreen().scale), contentMode: PHImageContentMode.Default, options: option, resultHandler: {(result, info)->Void in
self.imageView.image = result
})
}
}Thank you

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.

Hi, I am trying to store persistent changes to the photo library.
I know I can use a PHPersistentChangeToken to get the changes since that token, but I am not sure how to serialize this object and save it into a file.
I am also wondering if you can serialize a PHPersistentChangeFetchResult and store that in a file.
Cheers.

Goal is to get/save the captured photo (From default camera) immediately from my app when the app is in background.
When I capture a photo with default camera, photoLibraryDidChange(_:) function do not execute that time. But when I reopen my app, that time this function executes and give the images, which were captured in that particular time.
how to execute photoLibraryDidChange(_:) when app is in background?

Hello, after updating the physical device to iOS17, it seems there's an issue with the ImagePicker's functionality. In our app, even though NSItemProvider indicates canLoadObject(ofClass: UIImage.self) returns true, the method loadObject(ofClass: UIImage.self) { (object, error) consistently returns nil.
There's also a possibility that the same phenomenon is occurring with the standard Notes app's image picker, preventing images from being passed to the app.

Hello!
I am playing around with the PHPickerViewController and so far I was able to get the selected images by loading them into UIImage instances but I don't know how to get the selected video.
Below is the relevant implementation of the method: func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]):
let provider = result.itemProvider
guard provider.hasItemConformingToTypeIdentifier(AVFileType.mov.rawValue) else { return }
						provider.loadItem(forTypeIdentifier: AVFileType.mov.rawValue, options: nil) { (fileURL, error) in
								if let error = error {
										print(error)
										return
								}
								guard let videoURL = fileURL as? URL else { return }
								DispatchQueue.main.async {
										let fm = FileManager.default
										let destination = fm.temporaryDirectory.appendingPathComponent("video123.mov")
										try! fm.copyItem(at: videoURL, to: destination)
										let playerVC = AVPlayerViewController()
										playerVC.player = AVPlayer(url: destination)
										self.present(playerVC, animated: true, completion: nil)
								}
						}
I get crash trying to copy the item. It says the source file does not exists but the path looks real to me.
"The file “3C2BCCBC-4474-491B-90C2-93DF848AADF5.mov” couldn’t be opened because there is no such file." I tried it without copying first and just passing the URL to AVPlayer but nothing would play.
I am testing this on a simulator.
Thanks for help!

I am trying to display HDR Images (ProRAW) within UIImageView using preferredImageDynamicRange. This was shown in a 2023 WWDC Video
let imageView = UIImageView()
if #available(iOS 17.0, *) {
self.imageView.preferredImageDynamicRange = UIImage.DynamicRange.high
}
self.imageView.clipsToBounds = true
self.imageView.isMultipleTouchEnabled = true
self.imageView.contentMode = .scaleAspectFit
self.photoScrollView.addSubview(self.imageView)
I pull the image from PHImageManager:
let options = PHImageRequestOptions()
options.deliveryMode = .highQualityFormat
options.isNetworkAccessAllowed = true
PHImageManager.default().requestImage(for: asset, targetSize: self.targetSize(), contentMode: .aspectFit, options: options, resultHandler: { image, info in
guard let image = image else {
return
}
DispatchQueue.main.async {
self.imageView.image =image
if #available(iOS 17.0, *) {
self.imageView.preferredImageDynamicRange = UIImage.DynamicRange.high
}
}
}
Issue
The image shows successfully, yet not in HDR mode (no bright specular highlights, as seen when the same image ((ProRAW) is pulled on the native camera app.
What am I missing here?

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 &amp; 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?
