I've requested the authentication in my main app. PHPhotoLibrary.requestAuthorization(for: .readWrite) { status in } Add the privacy description in both the main app and the extension. But No matter the device is locked or unlocked. When I call let fetchResult = PHAsset.fetchAssets(with: .image, options: nil) let count = fetchResult.count the count is always zero, even after a new photo is saved to the album in the same session.

I have an app that edits photos in your library. When I call try CIContext().writeHEIFRepresentation(of: editedImage, to: fileURL, format: .RGBA8, colorSpace: originalImage.colorSpace!) The following is logged to the console: writeImageAtIndex:1012: ⭕️ ERROR: 'App' is trying to save an opaque image (5712x4284) with 'AlphaLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. What does that mean and how can I resolve it?

See Configuration Details at the end of this message. Despite numerous attempts, I have been unable to determine the correct syntax to fetch photo albums from my iPad Pro 13.0 using Xcode and Swift. All the photo album were synced to the iPad Pro 13-inch using the latest versions of Apple iTunes for Windows from an external Western Digital G-Drive hard drive (No iCloud). All synced albums appear under "From My Mac" on the iPad. I only want to access each album's photo and video count. See sample code snippet below. I have tried multiple subtype options and album types without success. Zero albums are always returned despite having around 3900 albums in the iPad Pro 13.0 photo library. Authorization to the photo library does not appear to be the problem. PHPhotoLibrary.requestAuthorization { status in if status == .authorized { let result = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: nil) if result.count == 0 { print("No albums found.") return } } } Any help or suggestions would greatly be appreciated.

We are currently in the process of migrating our application from using ALAssetsLibrary to PHPhotoLibrary to ensure compatibility with the latest versions of iOS. However, we have noticed a discrepancy in the file sizes of images obtained using PHPhotoLibrary compared to those obtained using ALAssetsLibrary. Specifically, we would like to understand the following points: 1.Reason for File Size Differences: What are the reasons for the difference in file sizes between images obtained using ALAssetsLibrary and those obtained using PHPhotoLibrary? Could you provide detailed information on the settings and options in PHPhotoLibrary that affect the size and quality of the images? 2.Optimal Settings: What are the optimal settings in PHPhotoLibrary to obtain images with the same quality and file size as those obtained using ALAssetsLibrary? If possible, could you provide code examples or recommended option settings?

I am using PHImageRequestOptions and PHImageManager to load images to my app. I use version.original and resizeMode.none, version.original and resizeMode.extract. Both used to work well but since iOS18 version.original and resizeMode.extract doesn't work anymore. The images are loaded but the they are not shown. (Only the frames?) Anyone knows why? Thank you for reading.

I have noticed a problem when a PHAsset creation request is made with the resource type PHAssetResourceType.photoProxy. let creationRequest = PHAssetCreationRequest.forAsset() creationRequest.addResource(with: .photoProxy, data: photoData, options: nil) creationRequest.location = location creationRequest.isFavorite = true After successfully saving the resulting asset through PHPhotoLibrary.shared().performChanges, I could verify it in the Photos app. I noticed that the created photo was initially marked as Favorite and that the location was added to the info as expected. The title of the image changes from "Today" to "" too. Next, the photo was refreshed, and location data was purged. However, the title remains unchanged and displays the . This refresh was also observed in the code. PHPhotoLibraryChangeObserver protocols func photoLibraryDidChange(_ changeInstance: PHChange) receives a change notification. The same asset has been changed, and there is no location information anymore. isFavorite information persists correctly. After debugging for a few hours, I discovered that changing the resource type to .photo fixes this issue. Location data is not removed in the Photos app, and no refresh callback is seen in func photoLibraryDidChange(_ changeInstance: PHChange). I initially used .photoProxy because in the AVCapturePhotoCaptureDelegate implementation class, I always get the call in func photoOutput(_ output: AVCapturePhotoOutput, didFinishCapturingDeferredPhotoProxy deferredPhotoProxy: AVCaptureDeferredPhotoProxy?, error: Error?). So here is where I am capturing the photo data as photoData = deferredPhotoProxy?.fileDataRepresentation().

Hi Apple Engineer, My App is using ImageCapture Framwork to connect DSLR Camera, Before iOS 18 this method is effective，but When I upgraded my iPhone and iPad, found my app can`t connect DSLR Camera, open Setting -> Privacy & Security -> Files and Folders permission, can‘t found my app, I swear it worked before iOS 18. I find other developers have the same problem. https://forums.developer.apple.com/forums/thread/756960 . https://developer.apple.com/forums/thread/765768. I also found a process for reproducing this problem in ios 18， Do reset all settings. Can you help me with this problem? Or tell me how to use the API properly.Look forward to your reply. Thank you very much.

We have a new photo sharing app (https://photodare.ca). We've had no issues with photos loading in North America and Caribbean, but so far 2 users (Germany, Netherlands) are saying they can't load photos even though they've proven they have permissions for photos enabled. I can't reproduce this in Canada. Anyone know about other permissions we need to setup for european countries, or is anyone in GDPR countries willing to try this for us? They were on 17.6.1. Thanks either way

I feel that IOS18 camera filters are over complicated and generate lower level results than iOS18 filters. I am really missing the Vivid filter. It was perfect on ios17.

Task { for await update in LockedCameraCaptureManager.shared.sessionContentUpdates { switch update { case .initial(let urls): print("frank: init \(urls)") await MainActor.run { let label = UILabel(frame: CGRect(x: 100, y: 100, width: 100, height: 30)) label.text = "frank test" label.textColor = .black UIViewController.getTop().view.addSubview(label) } case .added(let url): print("frank: add \(url)") case .removed(let url): print("frank: removed \(url)") default: break } } } why 'case .initial(let urls)': never never be executed? Can some one provide a sample code?

I am a developer working on iOS apps. In the demo, I planned to replace the local images with Heic format instead of PNG format, but the actual test results showed abnormalities on this device, while the other test devices displayed normally Heic images are converted by the built-in image conversion function on Mac. I tested multiple Heic images, but none of them were displayed and the image information returned nil,,but PNG images can be displayed normally. device information:

I’m working on real-time object detection using YOLOv8, but I only need to detect objects in approximately 40% of the screen area. Is it possible to limit the captureOut method to focus solely on that specific region of the screen? If this isn’t feasible, I’m considering an approach where the full-screen pixel buffer is captured and then cropped to the target area before running detection. However, I’m concerned about how this might affect real-time performance. I’d appreciate any insights on how to maintain real-time performance or suggestions for better alternatives. Thank you!

I am currently developing an application that requires access to GPS coordinates from photos on iOS. However, with the recent update to iOS 18 beta, I have encountered a challenge: I can only view photos within maps, and I am unable to access the GPS coordinates directly. Could you please provide guidance on how to enable or retrieve GPS coordinates from photos in the current iOS 18 beta version? Any insights or resources you could share would be greatly appreciated. Thank you for your assistance!

Hello, I’ve encountered an issue where a green line appears only in the thumbnail view of an image in the iPhone photo gallery. The green line is not present in the actual image itself. Here are some additional details: • The issue occurs only when saving the image as a JPEG. When saved as PNG, the green line does not appear. • The green line also shows up when using the PHAsset method requestImage(for:targetSize:). Depending on the targetSize, the resulting image may contain the green line. • Interestingly, this issue does not appear on iPhone Xs Max running iOS 15.2.1. However, the green line does appear on iPhone 15 Pro Max running iOS 18.0.1 when viewing the same image. I have attached the problematic image for your reference. Following images are the screen captures that shows the issue occurring on my iPhone. iPhone 15 pro max (iOS 18.0.1) iPhone Xs Max (iOS 15.2.1 ) Could this be related to a display or gallery app issue on iOS? Any advice or solutions would be greatly appreciated. Thank you!

I'm using PhotoKit in macOS to add photos to the user's library. Experimenting with Shared Photo Library, it seems that these new photos always end up in the Personal Library, not the Shared Library. I'd like to get them into the Shared Photo Library somehow. Is this possible? Things I've considered: A variation/option for PHAssetChangeRequest.creationRequestForAsset: doesn't seem to exist A property of PHAsset: can't find anything A special PHAssetCollection that I could add to: again, doesn't seem to exist

Hi: I am working with the ObjectCapture frameworks and sample code. Everything works great. We are trying to go from capturing 12MP images as in the sample code to capturing 48MP 6048 × 8064 images. We can't seem to get it to work. Any advice here?

This ideal gonna be cool: When people finish recording a video and later realize there's something else worth capturing, they can only create a second clip. But what if it were possible to reopen the first video and continue recording from where they left off? This would be a great convenience for many people

Hello developer community. I purchase recently my new iPhone 16 Pro Max; it is a premium device with great quality overall. However, I am having a big trouble shotting in ProRaw MAX (48 mode) with native camera. Just to be clear, the problem that i will describe do not happen in 3rd apps, such as ProCam; only with native camera. When I use ProRaw Max, and take the photo, and watch the photo in the gallery the image can’t load and render properly. Even, when I maximize the image to the maximum I can see pixelated portions, defects and super low resolution and excessive denoise. For comparison, this not occur with my previous iPhone 15 PM and/or when I capture photos from ProCam (same settings and configurations) in the 16PM. I proceed to take the photo, open the gallery and I see full of details, when zoomed to 100%. I tried to format the phone, reinstall the software via my mac. Tried even to look at some forums to find if there’s someone with the same issue, the information available so far is very low. I’m in contact with apple assistant from my country (Portugal), and they escalated this problem to the engineers. (that’s what I’ve been told). They did all the tests remotely (via analysis and improvement’s) and they told me that my phone is perfect in the hardware department. I will wait for the next days to be contacted again. I’m on iOS 18.0.1. (The last software available at this time). I tried multiple 16PM, from friends, family and stores (more or less 10 units), and they all showed the exact same problematic. I’m a professional photographer, so I find this frustrating and unacceptable. I would appreciate any additional suggestion or information. Thank you! Cannot add photos or files because they are bigger than 5Mb.

I would like to offer the functionality that the user aims the camera at a graph (including axes and scales) and the app detects the graph and the app replicates the graph using the image. I have the whole camera setup finished with a AVCaptureSession, VNDetectContoursRequest, VNImageRequestHandler, etc. However, now I get many many results so I guess I will now need to tell the image processing process what I am looking for. i.e. filter the VNContoursObservations. I 'think' I first need to detect two perpendicular lines (the two axes). How do I do that? If I do not see them, I can just ignore that input and wait for the next VNContoursObservation. When I found the axes of the graph, I will need to find the curve (graph) that I need to scan. Any tips on how I can find that curve and turn that curve into a bunch of coordinates? Thanks! Wouter
