I'm running this SwiftUI sample app for photos without any modifications except for adding my developer profile, which is necessary to build it. When I tap on the thumbnail to see the photo library (after granting access to my photo library), I see that some of the thumbnails are stuck in a loading state, and when I tap on thumbnails, I only see a low-resolution image (the thumbnail), not the full-resolution image that should load.
In the console I can see this error that occurs when tapping on a thumbnail to see the full-resolution image:
CachedImageManager requestImage error: The operation couldn’t be completed. (PHPhotosErrorDomain error 3164.)
When I make a few modifications necessary to run the app as a native macOS app, all the thumbnails load immediately, and clicking on them reveals the full-resolution images.

var config = PHPickerConfiguration()

I want only 'png' files to be displayed when the PHPickerViewController photo list is opened.
I've read this post : https://developer.apple.com/forums/thread/687415
In this post, it is mentioned that filtering image formats by PHPickerConfiguration is not possible (2 years ago).
Is it still not possible? Has issue 71832162 not been resolved?

From IOS 17.
Have an issue when saving video and reading it from PHPickerViewController. Video become into jpeg file
Code save video and I saw reason because i changed creationDate. But IOS 16 no bug here
doVertifyAccessAblum() {
DispatchQueue.global(qos: .background).async {
if let url = URL(string: videoURL), let urlData = NSData(contentsOf: url) {
let galleryPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0];
let filePath="\(galleryPath)/\(url.lastPathComponent).mp4"
DispatchQueue.main.async {
urlData.write(toFile: filePath, atomically: true)
PHPhotoLibrary.shared().performChanges({
let changeRequest = PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: URL(fileURLWithPath: filePath))
changeRequest?.creationDate = Date()
}) { success, error in
LOGGING.debug("Save video with status: success=\(success) error=\(String(describing: error))")
}
}
}
}

Hello,
We are trying to take pictures or grab frames using an iOS Phone 15 Pro. The items are moving down a conveyor belt. All we need to do is grab a photo of the item and crop it and save it as a jpg. Any ideas on what the best way to accomplish this is?
Thanks!

Hello,
I'm currently investigating the possibility of accessing my photos stored on my iCloud via a dedicated API, in order to create a photo portfolio.
However, after extensive research, I haven't found any documentation or public API allowing such access. I wonder if there are any future plans to make such an API available to third-party developers.
I would be grateful if you could provide me with information regarding the possibility of accessing an API for Apple Photos or any other solution you might suggest.
Thank you for your attention and assistance.
Yours sincerely
Owen

Is it possible to retrieve image metadata without requesting additional permission with the new SwiftUI PhotosPicker?
I can access metadata when using
picker( _ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult])
by using itemProvider. But for PhotosPicker, it seems that it's only possible by firstly retrieving PHAsset from PhotosPickerItem, and then by using requestContentEditingInput. Which require authorization for specific photo

First, App has linked with PhotosUI and Photos.
And, this problem never happened when complied with Xcode14.1 and Swift.
New APP is compiled with Xcode15.0.1. Code is not changed.
Step:
Set access "Selected Photos" for APP.
Restart APP. Try to access photos with PHPhotoLibrary functions , and then a system dialog appears. There are two buttons: "Select More Photos..." and "Keep Current Selection".
Choose "Keep Current Selection". (If choose "Select More Photos...", the app will not crash.)
Call "presentLimitedLibraryPicker(from controller: UIViewController)"
Crash log:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PHPhotoLibrary presentLimitedLibraryPickerFromViewController:]: unrecognized selector sent to instance 0x1064d66f0'

In iOS 16 this process is much faster than the same process in iOS 17
Is there a method to boost up the decoding speed?

My app uses PHLivePhoto.request to generate live photos, but memory leaks if I use a custom targetSize.
PHLivePhoto.request(withResourceFileURLs: [imageUrl, videoUrl], placeholderImage: nil, targetSize: targetSize, contentMode: .aspectFit) {[weak self] (livePhoto, info) in
Change targetSize to CGSizeZero, problem resolved.

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,
I want to create a photo portfolio (in VueJS) and I'd like to use my icloud photo library to store the photos.
Is there an API that allows me to access one or more albums in my photo library?

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.

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.

The native camera app on iPhone 15 can record videos directly in external hard drive. Is there an API to achieve the same in Photos framework?

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?

Is it possible to access "From my mac" photos/PHAssetCollection through PhotoKit in iOS?
"From my mac" photos/videos are media synced from a mac where iCloud Photos are turned off on the iOS device, like what we did in the ole' days before iCloud Photos.
I have set up an iOS device with "From my mac" albums present in Photos.app, but in my own app I don't seem to be able to access those collections/photos through PhotoKit using all the defined PHAssetCollectionTypes.
Are these directly synced photos simply not available through PhotoKit and you would have to revert to the deprecated ALAssetLibrary?
