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).

Hi there :) We're in our way to make an app to can communicate with DSLR camera by using ImageCaptureCore framework for PTP communication with the camera. In our app, we're sending some PTP commands to the camera by using requestSendPTPCommand(_:outData:completion:). This is our snipped-code to execute a PTP command. public extension ICCameraDevice { func sendCommand(command: Command) async { do { print("sendCommand ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++") print("sendCommand \(command.tag()) : sendCommand Started") let result = try await self.requestSendPTPCommand(command.encodeCommand().commandBuffer, outData: nil) let (data, response) = result print("sendCommand \(command.tag()) : sendCommand Finished") print("sendCommand data: \(data.bytes.count)") print("sendCommand response: \(response.bytes.count)") if !response.bytes.isEmpty { command.decodeResponse(responseData: response) } print("sendCommand \(command.tag()) : sendCommand Finished with response code \(command.responseCode)") print("sendCommand ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++") if command.responseCode != .ok { isRunning = false errorResponseCode = command.responseCode.rawValue print("response error with code = \(command.responseCode)") return } let copiedData = data.deepCopy() command.decodeData(data: copiedData) } catch { isRunning = false print("Error Send Command with error: \(error.localizedDescription)") } } } The function sendCommand(command: Command) async is called in a while-loop in async-await way. So that it needs to wait a sent command to finish before executing another command. The looping keeps running since the device connected to the camera. The result is, the process is running by no problem at all for several minutes, It can get camera's setting, device info, even its images. But then the problems occurred. The amount of time is random, some time it takes only 15 minutes, some time it takes 1 hour. There are 2 problems recorded in our case: 1. The requestSendPTPCommand(_:outData:completion:) result returning empty data without throwing any error, because the error never be caught in catch block. This is my printed result: sendCommand +++++++++++++++++++++++++++++++++++++ sendCommand GetObjectHandlesCommand : sendCommand Started sendCommand GetObjectHandlesCommand : sendCommand Finished sendCommand data: 0 sendCommand response: 0 sendCommand GetObjectHandlesCommand : sendCommand Finished with response code undefined sendCommand +++++++++++++++++++++++++++++++++++++ 2. It crashes with the last message in my logger: sendCommand +++++++++++++++++++++++++++++++++++++ sendCommand GetObjectHandlesCommand : sendCommand Started 2023-10-27 10:44:37.186768+0700 PTPHelper_Example[76486:11538353] [PTPHelper_Example] remoteCamera !

Using ImageCaptureCore, to send PTP devices to cameras via tether, I noticed that all of my Nikon cameras can take up to an entire minute for PTP events to start logging. My Canons and Sonys are ready instantly. Any idea why? I use the ICDeviceBrowser to browse for cameras, and then request to open the session. According to the docs, it says it's ready after it enumerates its objects? If that's the case, is there a way to bypass that? Even on an empty SD card it's slow.

The latest iPhone 15 Pro models support additional focal lengths on the main 24mm (1x) lens: 28mm ("1.2x") and 35mm ("1.5x"). These are supposed to use data from the full sensor to achieve optical quality images (i.e. no upscaling), so I would expect these new focal lengths to appear in the secondaryNativeResolutionZoomFactors array, just like the 2x option does. However, the activeFormat.secondaryNativeResolutionZoomFactors property still only reports [2.0] when using the main 1x lens. Is this an oversight, or is there something special (other than setting the zoom factor) we need to do to access the high-quality 28mm and 35mm modes? I'm wary of simply setting 1.2 or 1.5 as the zoom factor, as that isn't truly the ratio between the base 24mm and the virtual focal lengths.

Running on: iMac 27" 5k late 2015 - 64gb ram and a 16tb Pegasus Promise2 R4 raid5 via Thunderbolt. After trying Big Sur - found issues with Luminar Photo app, decided to return to Catalina on the iMac. Reformatted my internal drive and reinstalled Catalina 15.5 and reformatted the raid. But I keep getting the following message upon restarting: "Incompatible Disk. This disk uses features that are not supported on this version of MacOS" and my Pegasus2 R4 portion no longer appears on the desktop or in Disk Utility... Looked into this and discovered that it may be an issue of Mac OS Extended vs APFS The iMac was formatted to APFS prior to installing OS11 so I reformatted to APFS when returning to Catalina. The issues persisted so I re-reformatted from a bootable USB - this time to Mac OS Extended (journaled) and the issues seems to be resolved. The iMac runs slower on MacOS Ext, but it is running and the Raid is recognised... I'd love to go back to APFS but am afraid it will "break" things. Any thought on this would be welcome. Thanks Nick

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?

I am using DeepAR and PixelSDK in my project and these both SDK's has same file name "cameraVieewController" when I try to run application I get this error. Is their any solution to resolve this naming issue?

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?

hii developers currently i developing a ios camera app in that camera app i need to add features like photographic styles in ios 13 i need only that page view not filters this is my big problem..i used uipageviewcontroller and swipe gesture if i use page in background main camera view func also run, i used one button if i press the button i need views like photographic styles view just view this is my problem i can't do that so please if anyone can read this comment please and solve ..thanks in advance

I am trying to locate information or documentation on how to pull in photos from the iCloud Shared Albums, but have not been able to find anything yet. Dakboard is currently doing it so I know it is possible, but I cannot find an API or any documentation covering how to access the photos in a Shared Album for incorporation into web applications. Can anyone help?

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 } &#9;&#9;&#9;&#9;&#9;&#9;provider.loadItem(forTypeIdentifier: AVFileType.mov.rawValue, options: nil) { (fileURL, error) in &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;if let error = error { &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;print(error) &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;return &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;} &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;guard let videoURL = fileURL as?

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?

With AVFoundation, how do you set up the new 24MP capture on new iPhone 15 models? I strongly believed it was in videodevice.activeFormat.supportedMaxPhotoDimensions array, but not.

Hello! After recent talk on the WWDC2023 about HDR support and finding this documentation page on Applying Apple HDR effect on photos, I became very interested in the HDR Gain Map format. From documentation page it is clear how we can restore original HDR from SDR and Gain Map representation, but my question is - how from HDR we can convert back to the SDR + Gain Map representation? As I understand right know, conversion from HDR to SDR + Gain Map includes two steps: Tone mapping of HDR for getting correct SDR When we have both HDR and SDR, from equation in the documentation page we can calculate Gain Map Am I correct? If so, what tone mapping algorithm for HDR -> SDR conversion is used right know? Can't find any information about this in the internet:( Would be very grateful for your response!

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.)

The memory usage of the app increases as each image changes. Is there anyway to maintain a steady memory use?
