(Note: this is part 1 of a 3 part posting. See Part 2 or Part 3) At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Camera & Photos. WWDC25 Camera & Photos group lab ran for one hour at 6 PM PST on Tuesday June 10th, 2025 Introductory kick-off questions Question 1 Tell us a little about the new AVFoundation Capture APIs we've made available in the new iOS 26 developer preview? Cinematic Capture API (strong/weak focus, tracking focus)(scene monitoring)(simulated aperture)(dog/cat heads/groupIDs) Camera Controls and AirPod Stem Clicks Spatial Audio and Studio Quality AirPod Mics in Camera Lens Smudge Detection Exposure and Focus Rect of Interest Question 2 I built QR code scanning into my app, but on newer iPhones I have to hold the phone very far away from the QR code, otherwise the image is blurry and it doesn't scan. Why is this happening and how can I fix it? Every year, the cameras get better and better as we push the state of the art on iPhone photography and videography. This sometimes results in changes to the characteristics of the lenses. min focus distance newer phones have multiple lenses automatic switching behavior Use virtual device like the builtInDualWide or built in Triple, rather than just the builtInWide Set the videoZoomFactor to 2. You're done. Question 3 Last year, we saw some exciting new APIs introduced in AVFoundation in the health space. With Constant Color photography, developers can take pictures that have constant color regardless of ambient lighting. There are some further advancements this year. Davide, could you tell us about them? constant color photography is mean to remove the "tone mapping" applied to photograph captured with camera app, usually incldsuing artistic intent, and instead try to be a close as possible to the real color of the scene, regardless of the illumination constant color images could be captured in HEIF anf JPEG laste year. this year we are adding Support for the DICOM medical imaging photo format. It is a fomrat used by the health industry to store images related to medical subjects like MRI, skin problems, xray and so on. It's writable and also readable format on all OS26, supported through AVCapturePhotoOutput APIs and through the coregraphics api. for coregrapphics there is a new DICOM entry in the property dictionary which includes all the dicom availbale and defined propertie in a file. finder will also display all those in the info panel (Address why a developer would want to use it) - not for regualr picture taking apps. for those HEIF and JPEG are the preferred delivery format. use dicom if your app produces output that are health related, that you can also share with health providers or your doctors Main session developer questions Question 1 LiDAR vs. Dual Camera depth generation: Which resolution does the LiDAR sensor natively have (iPhone 16 Pro) and when to prefer LiDAR over Dual Camera? Both report formats with output resolutions (we don't advertise sensor resolution) Lidar vs Dual, etc: Lidar: Best for absolute depth, real world scale and computer vision Dual, etc: relative, disparity-based, less power, photo effects Also see: 2022 WWDC session "Discovery advancements in iOS camera capture: Depth, focus and multitasking" Question 2 Can true depth and lidar camera run at 60fps? Lidar can do 30fps (edited) Front true depth can do 60fps. Question 3 What’s the first class way to use PhotoKit to reimplement a high performance photo grid? We’ve been using a LazyVGrid and the photos caching manager, but are never able to hit the holy trinity (60hz, efficient memory footprint, minimal flashes of placeholder/empty cells) use the PHCachingImageManager to get media content delivered before you need to display it specify the size you need for grid sized display set the options PHVideoRequestOptionsDeliveryModeFastFormat, PHImageRequestOptionsDeliveryModeFastFormat and PHImageRequestOptionsResizeModeFast Question 4 For rending live preview of video stream, Is there performance overhead from using async and Swift UI for image updates vs UIViewRepresentable + AVCaptureVideoPreviewLayer.self? AVCaptureVideoPreviewLayer is the most efficient display path Use VDO + AVSampleBufferDisplayLayer if you need to modify the image data Swift UI image is optimized for static image content Question 5 Is there a way to configure the AVFoundation BuiltInLiDarDepthCamera mode to provide a depth map as accurate as ARKit at close range? The AVCaptureDepthDataOutput supports filtering that reduces noise and fills in invalid values. Consider using this for smoother depth maps Question 6 Pyramid-based photo editing in core image (such as adobe camera raw highlights and shadows)? First off you may want to look a the builtin filter called CIHighlightShadowAdjust Also the noise reduction in the CIRawFilter uses a pyramid-based algorithm. You can also write your own pyramid-based algorithms by taking an input image: down sample it by two multiply times using imageByApplyingAffineTransform apply additional CIKernels to each downsampled image as needed. use a custom CIKernel to combine the results. Question 7 Is the best way to integrate an in-app camera for a “non-camera” app UIImagePickerController? Yes, UIImagePickerController provides system-provided UI for capturing photos and movies. Question 8 Hello, my question is on Deferred Photo Processing? Say I have a photo capture app that adds a CIFilter to the capture. How can I take advantage of Deferred Photo Processing? Since I don’t know how to detect when the deferred captured photo is ready CIFilter can be called on the final at that point Photo will have to be re-inserted into the Photo library as adjustment Question 9 For shipping photo style assets in the app that need transparency what is the best format to use? JPEG2000? will moving to this save a lot of space comapred to PNG or other options? If you want lossless compression PNG is good and supports unpremutiplied alpha If you want lossy compression HEIF supports premutiplied or unpremutiplied alpha (Note: this is part 1 of a 3 part posting. See Part 2 or Part 3)

(Note: this is part 2 of a 3 part posting. See Part 1 or Part 3) At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Camera & Photos. WWDC25 Camera & Photos group lab ran for one hour at 6 PM PST on Tuesday June 10th, 2025 Question 10 Can we directly integrate auto-capture triggers (e.g., when image is steady or text is detected) using Vision and AVFoundation? Yes apps can use AVCaptureSession's VDO + AVCapturePhotoOutput, run vision on VDO buffers and capture photo when certain scene or text is detected. Just to be careful to run Vision on VDO buffers async so it doesn't cause frame drops. Question 11 What Camera or Photos framework features support working with images from external media, like connected cameras or SD cards? Any best practices? The ImageCaptureCore framework supports camera devices, memory cards, scanners read and write, where supported check out the docs to see how to browse connected devices, folders, files, etc. Question 12 Hi Brad, to follow up on your SwiftUI cautionary note: using AVCaptureVideoPreview inside a UIViewRepresentable, is okay, right? Thanks all for the great info! Yes, this is totally fine. AppKit or UIKit views inside appropriate SwiftUI representables should be equivalent performance Question 13 What’s the “right” way to transition media in my photos app between HDR modes? When I’m in a one-up view, we use HDR, but in other contexts (like thumbnail) we don’t want HDR. Is there a nice way to tone map? There’s a suite of new System Tone Mapper APIs in this years’ OSes CoreImage ImageKit CoreAnimation, CoreGraphics For example: CoreImage: new CISystemToneMap filter. CoreAnimation: layer.preferredDynamicRange = CADynamicRangeConstrainedHigh Using image views (NSImageView/UIImageView/SwiftUI Image/CALayer) support animations on preferredDynamicRange Can go from high to constrained to standard Tone mapping is provided by the system (CISystemToneMap for controllable example) Question 14 What is your recommendation to preprocess and upscale your depth map in order to render a realistic portrait mode image? One way to do this: the CIEdgePreserveUpsample CIFilter can be use to upsample a lower resolution depth map by using a higher resolution RGB image as a guide. Question 15 For buffering frames for later processing from real-time camera output should we prefer a AVSampleBufferDisplayLayer centered approach or AVCaptureVideoDataOutputSampleBufferDelegate centered approach? When would we use each? AVSampleBufferDisplayLayer and AVCaptureVideoDataOutputSampleBufferDelegate are used hand in hand for custom camera preview. For buffering for later processing, ensure you make copies of VDO buffers to not drop frames from the output Question 16 Hello, my question is on Deferred Photo Processing? Say I have a photo capture app that adds a CIFilter to the capture. How can I take advantage of Deferred Photo Processing? Since I don’t know how to detect when the deferred captured photo is ready CIFilter can be called on the final at that point Photo will have to be re-inserted into the Photo library as adjustment Question 17 Is digital zoom (e.g., 1.5x) before taking a photo the same as cropping the photo afterward? digital zoom upscales the image to output dimensions and cropping will yield a smaller output image while digital zoom will crop, it also upscales Question 18 How do you design camera interfaces that work for both casual users and photography enthusiasts? Progressive disclosure: Put the most common controls up front, and make it easy for pros to drill down. Sensible Defaults: Choose defaults that work well for casual users, but allow those defaults to be modified for photography enthusiasts A good philosophy is: Keep the simple things easy, make the hard things possible Question 19 Recent iPhone models introduced macro mode which automatically switch between lenses to take into account of the focal distance difference. Is there official API to implement this, or should I implement them myself using LiDAR values. Using builtInTripleCamera and builtInDualWideCamera will automatically switch to macro when available Question 20 a couple of years ago at WWDC, the option of replacing a camera with a virtual camera was mentioned. How does one do that - make the “physical” camera effectively disappear, so only the virtual camera is accessible to the user? You can't prevent the built-in camera from being available to the user Question 21 Can developers now integrate custom Core ML models with Vision for on-device photo analysis more seamlessly? Yes they can, use CoreMLRequest , provide their model container Been supported for a while (iOS 18/macOS 15) For more details go to Machine Learning & AI group lab Thursday use smaller images for better performance Question 22 What would you recommend for capture of the new immersive and spatial formats? To capture Spatial Video use AVCaptureMovieFileOutput’s spatialVideoCaptureEnabled property Not all device formats support spatial capture, check AVCaptureDevice.activeFormat.spatialVideoCaptureSupported See WWDC 2024 talk “Build compelling spatial photo and video experiences” for more details Question 23 You mentioned JPEG-XL. What is the current status of support on iOS and macOS for encoding and decoding? For decoding, we support JPEG-XL files in all our OSes, regular SDR files, as well as ISO HDR files. For encoding, we only support JPEG-XL for ProRAW DNG capture in the Camera app or via third-party AVFoundation APIs. If you have any requests for improvement or new features related to JPEG-XL, please file a Feedback request using the Feedback Assistant. (Note: this is part 2 of a 3 part posting.

Here are the highlights from the WWDC25 Group Lab for Camera & Photos. WWDC25 Camera & Photos group lab ran for one hour at 6 PM PST on Tuesday June 10th, 2025 Question 24 What’s the best approach for optimizing barcode scanning using AVFoundation or Vision in low-light or angled scenarios Turn on flash in low-light scenarios Lower framerate to improve exposure and reduce noise Wait until the capture is in focus/notify your user that they need to get closer Question 25 Recent iPhone models introduced macro mode which automatically switch between lenses to take into account of the focal distance difference. Is there official API to implement this, or should I implement them myself using LiDAR values. Using builtInTripleCamera and builtInDualWideCamera will automatically switch to macro when available Question 26 Is there a way to quickly create a thumbnail after the user selects an image with PhotosPicker? File provider API Additional questions from the WWDC25 in-person labs that occurred later in the WWDC week Question 1 When should I build my custom photo picker instead of using the system one? Always start with the system picker -> try embeddable customization APIs -> fallback to custom picker for very special needs Question 2 I'm building a new camera app for pros and I want to give my users the most un-processed image possible, and the most control over the capture as possible. How can I do that with AVCapture? If stills, Brief Bayer RAW capture overview, or Pro RAW if you want Apple's processing and dynamic range If video, talk about prores LOG. Custom exposure settings are available throguh the apis maybe global/local tonemapping discussion?

Since the OS was recently updated to 18.1.1 on my iPhone 15, I am no longer able to import my pictures into the Photos app on my iMac. I have to mention that my iMac is pretty old and is running OS High Sierra 10.13.6 and is not allowing me to update the OS to a newer version. Anyway, the main error message I get is: "Some items cannot be added to your Photo library because they may be an unrecognizable file format or the file may not contain valid data". Then, for each individual photo that failed to upload, the error message I get reads, "unable to read metadata. The file may be corrupt". However, videos import just fine from my iPhone to iMac. This was not a problem before the recent iPhone update. I tried closing the Photo app and reopening it. I tried restarting my iPhone and iMac but nothing seems to work. Any help would be much appreciated.

Hello Devs! Anyone has an idea if it is feasible to override the native camera in apple? So if a user have an app called "xyz" installed, when the user open his native camera and qr code is detected, we display a pop if he wants to continue with "xyz" Thanks

I explored several methods to trigger a 35mm camera connected via USB: 1- ICCameraDevice: Unable to make it work with Canon cameras (details). 2- Canon's EDSDK: Works but is complex to implement. 3- gPhoto2 (command-line): Simple to use but requires gPhoto2 to be installed. In your opinion, what is the most efficient way to trigger and download images via USB from Canon cameras?

I’m building a camera app using SwiftUI and UIKit (with UIViewControllerRepsrwsentable). My app already is able to capture photos, but I also want to implement the important feature - apply my custom image filter to the image for live preview in camera and when this image is saving to the photo library (like in the default Apple camera app with Photographic styles). My image filter must be pretty advanced because I’m a photographer and I trying to achieve the same colours as I have with my custom image preset in Lightroom. I want to control the image parameters such as basic (exposure, contrast, shadows, etc.), tone curves for each channel (Red, Green, Blue channels separately), HSL (for Red, Orange, Yellow, Green, Blue, Aqua, Purple and Magenta), apply colour grading and more. Currently I’m straggling with implementation of this. I tried to create a custom image filter using Metal (it works with saturation) but I’m not sure if it is the best approach. I need help and recommendations of how developers implement this complex thing in their apps (what technologies should I use and etc.)

Hi everyone, I am working on a 3D reconstruction project. Recently I have been able to retrieve the intrinsics from the two cameras on the back of my iPhone. One consideration is that I want this app to run regardless if there is no LiDAR, but at least two cameras on the back. IF there is a LiDAR that is something I have considered to work later on the course of the project. I am using a AVCaptureSession with the two cameras AVCaptureDevice: builtInWideAngleCamera builtInUltraWideCamera The intrinsic matrices seem to be correct. However, the when I retrieve the extrinsics, e.g., builtInWideAngleCamera w.r.t. builtInUltraWideCamera the matrix I get looks like this: Extrinsic Matrix (Ultra-Wide to Wide): [0.9999968, 0.0008149305, -0.0023960583, 0.0] [-0.0008256607, 0.9999896, -0.0044807075, 0.0] [0.002392382, 0.0044826716, 0.99998707, 0.0]. [-14.277955, -8.135408e-10, -0.3359985, 0.0] The extrinsic matrix of the form: [R | t], seems to be correct for the rotational part, but the translational vector is ALL ZEROS. Which suggests that the cameras are physically overlapped as well the last element not being 1 (homogeneous coordinates). Has anyone encountered this 'issue' before? Is there a flaw in my reasoning or something I might be missing? Any comments are very much appreciated.

I have a photo editing app which uses a simple Metal Render to display CIFilter output images. It works just fine in Swift 5 but in Swift 6 it crashes on starting the Metal command buffer with an error in the Queue : com.Metal.CompletionQueueDispatch (serial). The crash is occurring before I can debug.. I changed the command buffer to report MTLCommandBufferDescriptorStatus errorOptions = .encoderExecutionStatus. No luck with getting insight into the source of the crash.. Likewise the error is happening before any of the usual Metal debug tools are enabled. The Metal render works just fine in Swift 5 and also works fine with almost all of the Swift Compiler Upcoming feature flags set to Yes. [The "Default Internal Imports" flag is still No. (the number of compile errors with this setting is absolutely scary! but that's another topic) Do you have any suggestions on debugging or ideas on why the Metal library is crashing in Swift 6??? Everything is current release versions and hardware.

Hello Our application is backing up the user photos to some back end. When retrieving the asset data from the Photo Library, we set the flag 'accessNetworkAllowed' to true to get the assets that might be optimized in iCloud. In the application logs, we can see the message below, and it shows as coming from com.apple.photos.backend (PhotoKit) Missing prefetched properties for PHAssetAdjustmentProperties on <PHAsset: 0x160b1ec00> BCF5688F-F7A7-4196-AFC7-A84E8BD95F3E/L0/001 mediaType=1/0, sourceType=1, (5601x3734), creationDate=2022-01-24 23:36:05 +0000, location=0, hidden=0, favorite=0, adjusted=0 . Fetching on demand on the main queue, which may degrade performance. In particular, the message says 'Fetching on demand on the main queue' but I'm not sure if that means that PhotoKit will fetch on main queue or if that mean that our application is requesting the data on main queue. Anyone could clarify? thanks

I cannot find anything documentation re: isPrivacySensitiveAlbum. I've granted my app access to all photos. Not sure what else to try Code that triggers the crash: let options = PHFetchOptions() options.fetchLimit = 1 let assetColl = PHAssetCollection.fetchAssetCollections(withLocalIdentifiers: [localId], options: options) if assetColl.count > 0 { if let asset = PHAsset.fetchKeyAssets(in: assetColl.firstObject!, options: options) stack trace from here on `2023-04-15 06:34:41.628537-0700 DPF[33615:6484880] -[PHCollectionList isPrivacySensitiveAlbum]: unrecognized selector sent to instance 0x7ff09232aec0 2023-04-15 06:34:41.632378-0700 DPF[33615:6484880] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PHCollectionList isPrivacySensitiveAlbum]: unrecognized selector sent to instance 0x7ff09232aec0' *** First throw call stack: ( 0 CoreFoundation 0x00007ff80045478b __exceptionPreprocess + 242 1 libobjc.A.dylib 0x00007ff80004db73 objc_exception_throw + 48 2 CoreFoundation 0x00007ff8004638c4 +[NSObject(NSObject) instanceMethodSignatureForSelector:] + 0 3 CoreFoundation 0x00007ff800458c66 ___forwarding___ + 1443 4 CoreFoundation 0x00007ff80045ae08 _CF_forwarding_prep_0 + 120 5 Photos 0x00007ff80b8480e1 +[PHAsset fetchKeyAssetsInAssetCollection:options:] + 86 6 DPF 0x0000000100791029 $s3DPF16AlbumListFetcherV22loadKeyImageForLocalIdySo7UIImageCSgSSYaFTY0_ + 569`

I'm a new app developer and am trying to add a button that adds pictures from the photo library AND camera. I added the first function (adding pictures from the photo library) using the new-ish photoPicker, but I can't find a way to do the same thing for the camera. Should I just tough it out and use the UI View Controller struct that I've seen in all of the YouTube tutorials I've come across? I also want the user to be able to crop the picture in the app after they take a picture. Thanks in advance

Hi all, we are in the business of scanning documents and barcodes with the camera system of mobile devices. Since there is a wide variety of use cases, from scanning tiniest barcodes and small business cards to scanning barcodes or large documents from far distances we preferably rely on the triple camera devices, if available, with automatic constituent device switching. This approach used to be working perfectly fine. Depending on the zoom level (we prefer to use an initial zoom value of 2.0) and the focusing distance the iPhone Pro models switched through the different camera systems at light speed: from ultra-wide to wide, tele and back. No issues at all. Unfortunately the new iPhone 16 Pro models behave very different when it comes to constituent device switching based on focus distance. The switching is slow and sometimes it does not happen at all when the focusing distance changes. Especially when aiming for a at a distant object for a longer time and then aiming at a very close object that is maybe 2" away. The iPhone 15 Pro here always switches immediately to the ultra-wide camera, while the iPhone 16 Pro takes at least 2-3 seconds, in rare cases up to 10 seconds and sometimes forever to switch to the ultra-wide camera. Of course we assumed that our code is responsible for these issues. So we experimented with restricting the devices and so on. Then we stripped more and more configuration code but nothing we tried improved the situation. So we ended up writing a minimal example app that demonstrates the problem. You can find the code below. Execute it on various iPhones and aim at far distance (> 10 feet) and then quickly to very close distance (<5 inches). Here is a list of devices and our test results: iPhone 15 Pro, iOS 17.6: very fast and reliable switching iPhone 15 Pro, iOS 18.1: very fast and reliable switching iPhone 13 Pro Max, iOS 15.3: very fast and reliable switching iPhone 16 (dual-wide camera), iOS 18.1: very fast and reliable switching iPhone 16 Pro, iOS 18.1: slow switching, unreliable iPhone 16 Pro Max, iOS 18.1: slow switching, unreliable Questions: Does anyone else have seen this issue? And possibly found a workaround? Is this behaviour intended on iPhone 16 Pro models? Can we somehow improve the switching speed? Further the iPhone 16 Pro models also show a jumping preview in the preview layer when they switch the constituent active device. Not dramatic, but compared to the other phones it looks like a glitch. Thank you very much! Kind regards, Sebastian import UIKit import AVFoundation class ViewController: UIViewController { var captureSession : AVCaptureSession! var captureDevice : AVCaptureDevice! var captureInput : AVCaptureInput! var previewLayer : AVCaptureVideoPreviewLayer! var activePrimaryConstituentToken: NSKeyValueObservation? var zoomToken: NSKeyValueObservation? override func viewDidLoad() { super.viewDidLoad() } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) checkPermissions() setupAndStartCaptureSession() } func checkPermissions() { let cameraAuthStatus = AVCaptureDevice.authorizationStatus(for: AVMediaType.video) switch cameraAuthStatus { case .authorized: return case .denied: abort() case .notDetermined: AVCaptureDevice.requestAccess(for: AVMediaType.video, completionHandler: { (authorized) in if(!authorized){ abort() } }) case .restricted: abort() @unknown default: fatalError() } } func setupAndStartCaptureSession() { DispatchQueue.global(qos: .userInitiated).async{ self.captureSession = AVCaptureSession() self.captureSession.beginConfiguration() if self.captureSession.canSetSessionPreset(.photo) { self.captureSession.sessionPreset = .photo } self.captureSession.automaticallyConfiguresCaptureDeviceForWideColor = true self.setupInputs() DispatchQueue.main.async { self.setupPreviewLayer() } self.captureSession.commitConfiguration() self.captureSession.startRunning() self.activePrimaryConstituentToken = self.captureDevice.observe(\.activePrimaryConstituent, options: [.new], changeHandler: { (device, change) in let type = device.activePrimaryConstituent!.deviceType.rawValue print("Device type: \(type)") }) self.zoomToken = self.captureDevice.observe(\.videoZoomFactor, options: [.new], changeHandler: { (device, change) in let zoom = device.videoZoomFactor print("Zoom: \(zoom)") }) let switchZoomFactor = 2.0 DispatchQueue.main.async { self.setZoom(CGFloat(switchZoomFactor), animated: false) } } } func setupInputs() { if let device = AVCaptureDevice.default(.builtInTripleCamera, for: .video, position: .back) { captureDevice = device } else { fatalError("no back camera") } guard let input = try?

What is the purpose of AdjustmentsSecondary.data included in the PHAssetResource for a cleaned-up image? When using creationRequest.addResource, what should be set for the PHAssetResourceType? If I set the PHAssetResourceType as follows to create an asset, it appears correctly in the camera roll. However, when attempting to edit the image in the Photos app, the app crashes: IMG_5332.HEIC → .photo FullSizeRender.HEIC → .fullSizePhoto Adjustments.plist → .adjustmentData AdjustmentsSecondary.data → .adjustmentData

for a while i had one photo widget (no special app, just the standard apple one) and it was set to shuffle to an album of pics of my bf. no problems at all. a few weeks later i added one to shuffle through an album of pics of my cat, and that one worked fine, but it made the one of my bf stop working, and it just showed a blank white widget, no error message or anything. so i removed the one of my cat hoping the one of my bf would go back to working, and it didn’t. i only have the widgets for find my, my bank, and then apps on my home screen otherwise.

Hey, I have a complex CIFilter chain I'm trying to debug to improve processing time. Is there any documentation on what all the colours mean and the naming, e.g. sRGB Linear_to_workspace? Thanks Alex

Support external cameras in your iPadOS app and use Swift to read multiple camera feeds? thanks

I set both the AVCapturePhotoOutput and the AVCapturePhotoSettings with maxPhotoDimensions = .init(width: 8064, height: 6048), but still get the 12mp photo.

is forKey:fileSize considered accessing non-public API? has your app been rejected at review stage due to this? let resources = PHAssetResource.assetResources(for: asset) if let resource = resources.first { if let fileSize = resource.value(forKey: "fileSize") as? Int { return fileSize } }

Hello everyone, I need some help about this things. If you also know, pls comment. Overview We are planning to develop an app using the “Support external cameras in your iPadOS app” feature introduced in iPadOS 17. Before implementing this feature, it is necessary for the iPad to recognize external cameras. However, among the iPad models compatible with iPadOS 17, we have found that some of the iPads owned by our development team can recognize external cameras, while others cannot. If you have any reports regarding compatibility issues or information on how to resolve these problems, please share them with us. Detailed Explanation: The results of our investigation are as follows: External Camera Used: A 360-degree camera Devices Firmware RICOH Theta X 2.61.0（2024/12/26Latest） RICOH Theta Z1 Tested iPad Devices Firmware Status 12.9インチiPad Pro（第3世代） IOS 17.5.1 OK 11インチiPad Pro（M4） IOS 18.2 NG Verification Method Step 1: Power on the iPad and the external camera, ensuring both are ready for connection. Step 2: Connect the iPad and the external camera using a USB-C cable. Step 3: Launch FaceTime on the iPad and check the displayed camera feed. If the external camera is recognized, the feed from the external camera will be displayed.

Hey everyone😊, I am building an app that includes a live camera feed preview. That's all I need to do along side identifying the images with createML's image classification. I don't need to capture images at all. I've seen some very complicated tutorials. I just want to use a couple of lines of code.

Our app filters the photo library to a certain date range for ease of picking photos. However, to do this, we have to require full permissions to the photo library. We would like to use the PHPickerViewController and have it filter the results by the assets creation date? This would allow us to use it. I see other filter options, but not this one. And if it isn't there, is this something that is being thought about or on a roadmap?

Hello, I am experiencing slow image retrieval when using the requestImageForAsset:targetSize:contentMode:options:resultHandler: method in my application. The delay is significantly impacting the performance of my app. Here are the details of my implementation: for (PHAsset *asset in assets) { @autoreleasepool { PHImageManager *imageManager = [PHImageManager defaultManager]; PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init]; options.synchronous = YES; options.deliveryMode = PHImageRequestOptionsDeliveryModeFastFormat; options.resizeMode = PHImageRequestOptionsResizeModeNone; [imageManager requestImageForAsset:asset targetSize:CGSizeMake(100, 100) contentMode:PHImageContentModeAspectFill options:options resultHandler:^(UIImage *thumbnail, NSDictionary *info) { CameraRollCellDto *cellDto = [[CameraRollCellDto alloc] init]; cellDto.index = index; cellDto.thumbnail = thumbnail; cellDto.propertyDate = asset.creationDate; if (self.segmentedTorikomi.selectedSegmentIndex == SEG_INDEX_IKKATSU) { cellDto.isSelected = YES; } else { cellDto.isSelected = NO; } [list addObject:cellDto]; }]; index++; } } Has anyone else encountered this issue? Are there any known solutions or optimizations that can help improve the speed of image retrieval using this method? Thank you for your assistance.
