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

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!

Hello there!
I am trying to use PHPickerViewController to load videos, but I got a problem: I could load some videos only not all.
I refer to the existing thread - https://developer.apple.com/forums/thread/652695, but dosen't work.
This is the code I persent PHPickerViewController
var config = PHPickerConfiguration()
config.selectionLimit = 1
config.filter = .videos
config.preferredAssetRepresentationMode = .current
let picker = PHPickerViewController(configuration: config)
picker.delegate = self
present(picker, animated: true, completion: nil)
Below is the relevant implementation of the method: func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]):
picker.dismiss(animated: true, completion: nil)
for result in results {
result.itemProvider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { (url, error) in
if let error = error {
print(error)
return
}
guard let url = url else { return }
let fileName = "\(Date().timeIntervalSince1970).\(url.pathExtension)"
let newUrl = URL(fileURLWithPath: NSTemporaryDirectory() + fileName)
try? FileManager.default.copyItem(at: url, to: newUrl)
DispatchQueue.main.async {
self.playVideo(newUrl)
}
}
}
Before I print error in line 5, Xcode printed 3 lines of error:
[AXRuntimeCommon] Unknown client: TestPHPicker

And I print error in line 5:

For some videos I can load successfully, and some videos I got error. I don't know why this happened.
I am testing this on an iPhone X iOS 14.0(18A373). Xcode 12.0 (12A7209).

Hi, I'm wondering if it is possible to manipulate the "other" Photos library with PhotoKit, not the only System one.
PhotoKit documentation only mentioned object of PHPhotoLibrary class, which is "a shared object that manages access and changes to the user’s shared photo library". But the Photos app in macOS allows to create and switch between multiple photo libraries.
Thanks.

I want to get only 'food' image from user's album.
Can I fix or set placeholder to search 'food' automatically in PHPicker ?
I just need the way that user don't need to manually enter the 'food' and search the image.

I use the following code to parse Photo metadata and this works well. However, I am unable to pull the new iOS 14 "caption" from this metadata (it worked in early iOS 14 betas, but has since stopped working in the GM.) Does anyone know how I can get the caption data from a PHAsset? Thanks!

options.isNetworkAccessAllowed = true
asset.requestContentEditingInput(with: options, completionHandler: {(contentEditingInput, _) -> Void in

let fullImage = CIImage(contentsOf: url)
// get all the metadata
self.allPhotoMetadata = fullImage?.properties ?? [:]

Is this a bug or the expected behaviour?
var progress = itemProvider.loadFileRepresentation(
forTypeIdentifier: id,
completionHandler: { [self] (u, error) in
//...
})
var timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { [self] timer in
print("\(progress?.completedUnitCount)/\(progress?.totalUnitCount)")
}
this always prints 100/100
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)
}
}
}
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?
Using Xcode 13 beta 4, I seem to have lost the ability to access user-created photo albums with PhotoKit (via PHAssetCollection.fetchAssetCollections). When I request albums of the type .smartAlbum, I get all the Smart Albums. However when I request .album, I get 0 results. Has anyone else run into this?
Here's some example code:
import SwiftUI
import Photos
struct ContentView: View {
@State var status: PHAuthorizationStatus = PHPhotoLibrary
.authorizationStatus(for: .readWrite)
private static var collectionOptions: PHFetchOptions {
let reverseChron = PHFetchOptions()
reverseChron.sortDescriptors = [NSSortDescriptor(keyPath: \PHAssetCollection.endDate, ascending: false)]
return reverseChron
}
var body: some View {
VStack {
Text("Welcome!")
.padding()
if status == .authorized {
Button("Load photos") {
let userAlbums = PHAssetCollection.fetchAssetCollections(
with: .album,
subtype: .any,
options: ContentView.collectionOptions
)
print("List of albums:")
for i in 0..<userAlbums.count {
let album = userAlbums[i]
print(album.localizedTitle ?? "[No title]")
}
}
}
}.onAppear() {
PHPhotoLibrary.requestAuthorization(for: .readWrite) { aStatus in
status = aStatus
}
}
}
}
struct ContentView_Previews: PreviewProvider {

ContentView()

I have been unable to capture Live Photos using UIImagePickerController. I can capture still photos and even video (which is not my scenario but I checked just to make sure), but the camera does not capture live photos. The documentation suggests it should (source):
To obtain the motion and sound content of a live photo for display (using the PHLivePhotoView class), include the kUTTypeImage and kUTTypeLivePhoto identifiers in the allowed media types when configuring an image picker controller. When the user picks or captures a Live Photo, the editingInfo dictionary contains the livePhoto key, with a PHLivePhoto representation of the photo as the corresponding value.
I've set up my controller:
let camera = UIImagePickerController()
camera.sourceType = .camera
camera.mediaTypes = [UTType.image.identifier, UTType.livePhoto.identifier]
camera.delegate = context.coordinator
In the delegate I check for the Live Photo:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let live = info[.livePhoto] as? PHLivePhoto {
// handle live photo
} else if let takenImage = info[.originalImage] as? UIImage, let metadata = info[.mediaMetadata] as? [AnyHashable:Any] {
// handle still photo
}
}
But I never get the Live Photo.
I've tried adding NSMicrophoneUsageDescription to the info.plist thinking it needs permissions for the microphone, but that did not help. Of course, I've added the NSCameraUsageDescription to give camera permissions.
Has anyone successfully captured Live Photos using UIImagePickerController?

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.

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).
Since iOS16 introduced the shared albumn, is there an API for developers to access the assets inside that shared albumn?

Is this accessible from Swift directly?
Visual Look Up
Lift subject from background
Lift the subject from an image or isolate the subject by removing the background. This works in Photos, Screenshot, Quick Look, Safari, and more.
Source: macOS Ventura Preview - New Features - Apple
I see that Shortcuts now has a native Remove Background command that wasn't there in iOS 25 or MacOS 12. Is there any way to call that from Swift besides x-callback url schemes?

Hi, I'm on an iOS 14 Pro Max. We were so eager to try the iCloud Shared Photo Library, my wife and I. She is on an iPhone 14 Pro. All was fine when we were on the beta, but when we switched back to regular iOS 16 public release I noticed that our photos were no longer syncing. I tried to remove her from the photo library and start over after upgrading us both to iOS 16.1 Build 20B5056e, but now nothing works.
We have 41,160 photos & 4,354 videos all told. Right now, your beta is hung up somewhere on my iPhone 14 Pro Max on "Deleting Shared Library", and moving everything back from my shared library back to my personal library in order for me to go back to "normal." On her Pro, it's stuck on "Leaving Shared Library". In my personal library I can see 19,056 photos and 3,092 videos.
In my shared library at beta.icloud.com I can see 22,104 photos & 1262 videos. All of these totals of course add up to 41,160 photos and 4,354 videos as you can see. But it's stuck. It is stuck, and I don't know where...it will not transfer the remaining 22,104 photos and 1,262 videos back into my personal library in order for me to start fresh. I can still see them on beta.icloud.com, but my iPhone will not budge as far as moving them back, and neither will hers as far as leaving the shared library. Please tell me my photos are not lost nor unrecoverable.
I've tried suggestions such as those at https://forums.macrumors.com/threads/shared-photo-library-risky.2359656/ posted by Fibrozyt, but to no avail. Nothing triggers the sync to resume, and so I have 22,104 photos and 1,262 videos that are stuck in some phantom zone "Shared Library" online now.
Please tell me a future iOS Beta solves this, because we cannot sync our photos. I've up-down-rebooted both iPhones, I've killed off the apps, I've turned off iCloud photos and turned it back on on both devices...I've looked for a way in beta.icloud.com to move them back to my personal library so that we could start again. Nothing is working. HELP please. These are precious memories of course, of my wife, our family, our wedding, our kids, our homes, our lives.

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

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." UserInfo={NSUnderlyingError=0x2804a8e70 {Error Domain=NSCocoaErrorDomain Code=4097 "connection from pid 19420 on anonymousListener or serviceListener" UserInfo={NSDebugDescription=connection from pid 19420 on anonymousListener or serviceListener}}}
Error copying file type public.image. Error: Error Domain=NSItemProviderErrorDomain Code=-1000 "Cannot load representation of type public.image" UserInfo={NSLocalizedDescription=Cannot load representation of type public.image, NSUnderlyingError=0x280480540 {Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application."

We observed that on some devices, loading the image will actually work after a short time (~30 sec), but on others it will always fail.
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?
