We implemented the new PHPicker and have run into an issue we haven't been able to replicate on our own devices but see a lot of users running into it. The problem is an error after getting the PHPickerResults and trying to get the UIImages. Because the user can select several images at once, what we do is get the results and iterate over each itemProvider object. I'm following apple's guidance and checking if itemProvider canLoadObjectOfClass:UIImage.class, before executing itemProvider loadObjectOfClass:UIImage.class. However we are getting hundreds of reports of users where this last method returns an error. Firstly, this is how we configure our PHPickerViewController: PHPickerConfiguration *configuration = [[PHPickerConfiguration alloc] init]; configuration.selectionLimit = self.pictureSelectionLimit; configuration.filter = PHPickerFilter.imagesFilter; configuration.preferredAssetRepresentationMode = PHPickerConfigurationAssetRepresentationModeCurrent; PHPickerViewController *pickerViewController = [[PHPickerViewController alloc] initWithConfiguration:configuration]; pickerViewController.delegate = self; pickerViewController.modalPresentationStyle = UIModalPresentationFullScreen; [viewController presentViewController:pickerViewController               animated:YES              completion:nil]; And this is what we do with the PHPickerResult. This is a method that returns a block with an array of an object NewPicture instantiated with the UIImage I should be getting. NSMutableArray *picArray = [[NSMutableArray alloc] init]; NSArray *itemProviders = [self.results custom_map: ^id _Nullable (PHPickerResult *_Nonnull current) {   return current.itemProvider; }]; dispatch_group_t dispatchGroup = dispatch_group_create(); for (NSItemProvider *itemProvider in itemProviders) { dispatch_group_enter(dispatchGroup); /**  We cannot properly retrieve raw type images with the current authorization status.  If the image is of type raw, we ignore it. */ if ([itemProvider hasItemConformingToTypeIdentifier:@"public.camera-raw-image"]) { NSException *exception = [NSException exceptionWithName:@"ImageIsTypeRaw"                         reason:[NSString stringWithFormat:@"Object is type raw. ItemProvider: %@", itemProvider.description]                        userInfo:nil]; // Log exception... dispatch_group_leave(dispatchGroup); continue; } if ([itemProvider canLoadObjectOfClass:UIImage.class]) { [itemProvider loadObjectOfClass:UIImage.class completionHandler: ^(__kindof id NSItemProviderReading _Nullable object, NSError *_Nullable error) {   if ([object isKindOfClass:UIImage.class]) { NewPicture *picture = [[NewPicture alloc]initWithImage:object]; [picArray addObject:picture]; }   if (error) { NSException *exception = [NSException exceptionWithName:@"CouldNotLoadImage"                         reason:[NSString stringWithFormat:@"Object is nil. UserInfo: %@", error.userInfo]                        userInfo:error.userInfo]; // Log exception... }   dispatch_group_leave(dispatchGroup); }]; } } dispatch_group_notify(dispatchGroup, dispatch_get_main_queue(), ^{ picturesBlock(picArray); }); The most common error we see our users are getting is: Object is nil. UserInfo: { NSLocalizedDescription = "Cannot load representation of type public.jpeg"; NSUnderlyingError = "Error Domain=NSCocoaErrorDomain Code=260 \"The file \U201cversion=1&uuid=*&mode=current.jpeg\U201d couldn\U2019t be opened because there is no such file.\" UserInfo={NSURL=file:///private/var/mobile/Containers/Shared/AppGroup/*/File%20Provider%20Storage/photospicker/version=1&uuid=*&mode=current.jpeg, NSFilePath=/private/var/mobile/Containers/Shared/AppGroup/*/File Provider Storage/photospicker/version=1&uuid=***&mode=current.jpeg, NSUnderlyingError=0x283822970 {Error Domain=NSPOSIXErrorDomain Code=2 \"No such file or directory\"}}"; } I'm having a really hard time understanding why this sometimes fails. I'd really appreciate it if someone could give me a hand with this. I'm attaching the stack trace: stack_trace - https://developer.apple.com/forums/content/attachment/051f7018-05ff-4ad1-a626-29f248d0b497

My recording was stopped due to low battery and phone shutdown. When I reopen my app, the recorded ".mov video"(around 8GB) file is not moving/copying to PHPhotoLibrary and it shows internalError which is hard to understand the exact reason for denying to add the video file to PHPhotoLibrary. Error Domain=PHPhotosErrorDomain Code=-1 \"(null)\") So How to resolve such kind of internalError while adding assets to PHPhotoLibrary? Thanks & Regards, Natarajan S

Is there a way to update the metadata of a AVAsset/PHAsset to show a different still photo when the asset is not being played? If so what class should I look at to update the AVAsset or PHAsset? I am looking to edit the asset itself, not show a layer over the video. I would prefer to do this without trimming the video.

What is Error Domain=com.apple.photos.error Code=46104 mean? This error appears when I try to create an album on iOS14. case: User first gives AddOnly authorization and then gives ReadWrite authorization. After I get the ReadWrite authorization, create an album. code reference: [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{     PHAssetCollectionChangeRequest *request = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:albumName]  albumPlaceholder = [request placeholderForCreatedAssetCollection]; } completionHandler:^(BOOL success, NSError * _Nullable error) { // success is NO, error is "Error Domain=com.apple.photos.error Code=46104"  }]; The supplementary log information for the above question is as follows: 2020-08-17 11:28:19.470871+0800 XXXX[4255:1139139] CoreData: XPC: Unable to connect to server with options { NSXPCStoreServerEndpointFactory = "<PLXPCPhotoLibraryStoreEndpointFactory: 0x280ce8760>"; skipModelCheck = 1;} 2020-08-17 11:28:19.479533+0800 XXXX[4255:1139139] CoreData: XPC: Unable to load metadata: Error Domain=NSCocoaErrorDomain Code=134060 "关键数据出错。" UserInfo={Problem=Unable to send to server; failed after 8 attempts.} 2020-08-17 11:28:19.483149+0800 XXXXX[4255:1139139] [error] error: addPersistentStoreWithType:configuration:URL:options:error: returned error NSCocoaErrorDomain (134060) CoreData: error: addPersistentStoreWithType:configuration:URL:options:error: returned error NSCocoaErrorDomain (134060) CoreData: annotation: userInfo:CoreData: annotation: Problem : Unable to send to server; failed after 8 attempts.

When saving the video, if the AddOnly permission is taken first and then the ReadWrite permission is taken, the performChanges method will freeze for more than 10 seconds before calling the completionHandler. The following is the log information: [Generic] Failed to connect to XPC PhotoLibraryStore file:///var/mobile/Media/PhotoData/Photos.sqlite with options { NSXPCStoreServerEndpointFactory = "<PLXPCPhotoLibraryStoreEndpointFactory: 0x280700d00>"; These problems only occur during a cold launch when the AddOnly permission is taken first and then the ReadWrite permission is taken. Whether the app only takes the AddOnly permission, only takes the ReadWrite permission, or closes the app after authorization and reopens it will not happen.

The app is a webview where there is a form where an input file image is loaded. The problem is that when selecting an image from the camera, the app crashes. If you can upload images from Photo LIbrary and Choose File

There are list of frames displayed at the bottom of the screen when videos are played on Photos app in iPhone. Which API is used for this functionality in iOS photo app. Is it possible to check this ?

There's only a single function under PHPickerViewControllerDelegate which is didFinishPicking according to the documentation. How do I implement dismiss for the Cancel button that comes along when tapping out with PHPickerViewController? Have no problem if continue using UIImagePickerControllerDelegate, as it comes with imagePickerControllerDidCancel . However, if I were to implement with the new PHPickerViewController that currently only have a single function, how to enable proper dismiss right on the click of Cancel button instead of just relying the swipe down to dismiss the screen. Kindly advise. Thanks.

I would like to be able to select a photo in iOS using Swift from the Photos library using UIImagePicker and copy all the image (with modified Exif metadata) to a new photo which I save in Photos. If I use UIActivityViewController to choose the save option (from copy/save/assign to contact/print/add to shared album/save to file), the input image Exif metadata is not transferred when I create a new UIimage from the loaded image data with the modified metadata. How can get the image with modified Exif metadata attached to the saved photo?

The same code can generate livePhoto in iOS 14, but can't generate livePhoto in iOS 15.1. Does anyone know how to solve this problem? please help me. thanks

Work well in iOS 15.0 but after upgrading to iOS 15.1, the codes can't get worked. _ = PHLivePhoto.request(withResourceFileURLs: [pairedVideoURL, pairedImageURL], placeholderImage: nil, targetSize: CGSize.zero, contentMode: PHImageContentMode.aspectFit, resultHandler: { (livePhoto: PHLivePhoto?, info: [AnyHashable : Any]) -> Void in if let isDegraded = info[PHLivePhotoInfoIsDegradedKey] as? Bool, isDegraded { return } DispatchQueue.main.async { completion(livePhoto, (pairedImageURL, pairedVideoURL)) } })

tl;dr; Is there a way to ensure that only "Never" and "Read and Write" appear under Settings -&gt; App Name -&gt; Photos on devices running iOS 14 or higher? The Issue: The enhanced image library access permissions incorporated as part of iOS 14 are creating problems with a custom image selection flow created for an app and I'm just curious if there is a way to eliminate the "Selected Photos" option from the app settings until the app can be fully updated to offer users the enhanced security. I've removed the "Select Photos..." option from the iOS permission alert viewcontroller for the Images Library by setting the value for the PHPhotoLibraryPreventAutomaticLimitedAccessAlert key to 'true' as recommended in the Apple documentation: https://developer.apple.com/documentation/photokit/phauthorizationstatus/limited However, if the device is running iOS 14 or higher, the option for "Selected Photos" is still available when I go to the App's settings in the device's Settings menu. If a user interacts with permissions at this level the app does not function properly. I was wondering if anyone has experienced this as well and possibly come up with an interim solution.

Am using a Supervised Device with 15.4 OS Scenario: I have tried to push the Restriction payload to Device , with value true for "allowOpenFromUnmanagedToManaged" key . case 1: When i try to open a photo from Photo Library and try to open in with any Managed App ,the suggestions for managed app is not listed there. (Working as Expected) My Problem is: case 2: But when i open the Managed App and Try to add a photo , It allows me to open the Photo Library ,from where i can add it. If Sharing data from unmanaged to managed app is restricted, then it shouldn't be added in case2 ,Right? FYI: The managed App i have used in Outlook App Can Anyone Help me this strange Behaviour? Thanks In Advance

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.)
