Hi, I face a problem that I could not scan a specific Code 39 barcode with Vision framework. We have multiple barcode in a label and almost all Code 39 can be scanned, but not for specific one. One more information, regardless the one that is not recognized with Vision can be read by a general barcode scanner. Have anyone faced similar situation? Is there unique condition to make it hard to scan the barcode when using Vision?(size, intensity, etc) Regards,

iPhone 12 is updated to iOS 18 and my Mac is running macOS Sequoia. The first time I requested the Scan Document feature from my Mac to iPhone, it opened the camera and scanned successfully. However, after that, the Scan Document feature crashed. I attempted multiple times to reopen the Scan Document feature on my iPhone, but it has stopped working entirely.

VNDocumentCameraViewController has no option to switch or flip back camera to front one. Is there any way to use front camera on VNDocumentCameraViewController?

I don't get cameraFrame from cameraFrameUpdates in vision pro app, why it's no getting , where I am doing wrong in code please guide me. for await cameraFrame in cameraFrameUpdates { print("cameraFrame:: (cameraFrame)") } var body: some View { VStack { image .resizable() .scaledToFit() if(self.finalImage != nil){ self.finalImage! .resizable() .scaledToFit() }else{ image .resizable() .scaledToFit() } } .task { if #available(visionOS 2.0, *) { guard CameraFrameProvider.isSupported else { print("CameraFrameProvider not supported.") return } let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions: [CameraFrameProvider.CameraPosition.left]) let cameraFrameProvider = CameraFrameProvider() do { try await arkitSession.run([cameraFrameProvider]) } catch { guard let sessionError = error as? ARKitSession.Error else { preconditionFailure("ARKitSession.run() returned a non-session error: \(error)") print("ARKitSession.run() returned a non-session error: \(error)") } } guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]) else { preconditionFailure("Failed to get an async sequence for the first format.") print("Failed to get an async sequence for the first format.") } print("cameraFrameUpdates:: \(cameraFrameUpdates)") for await cameraFrame in cameraFrameUpdates { print("cameraFrame:: \(cameraFrame)") print("Camera Frame ::: LEFT :: \(cameraFrame.sample(for: .left))") guard let leftSample = cameraFrame.sample(for: .left) else { print("CameraFrameProviderSample - Nil camera frame left sample") print("CameraFrameProviderSample - Nil camera frame left sample") continue } self.pixelBuffer = leftSample.pixelBuffer print(" ======== PIXEL BUFFER ::: \(self.pixelBuffer) ========") self.finalImage = self.setImage() } } else { // Fallback on earlier versions } } }

Is there a way to retrieve the position of the main window in Vision OS? I'd like to implement a feature where users can drag the window and have a 3D model follow it

I have tested my application in iOS 15, 16, 17 Version in that vision kit reading value in Horizontal direction once I got updated my device to iOS 18.0 beta value was reading as in vertical direction The build was generated in Xcode 13.4.1. Team please help to understand why this and need to change anything in code level

Essentially, I'm trying to find the most straightforward/simple way to outline an Image with varying contours. The intention is similar to the way iMessage allows you to add an outline to a sticker. The "goal" in the example is simply the input image on top of the outline.

App crashes on iOS 16.4 when there is usage for ImageAnalysisInteraction api from VisionKit. App crashes before even starts. Here is output: dyld[3240]: Symbol not found: _$s9VisionKit24ImageAnalysisInteractionC7subject2atAC7SubjectVSgSo7CGPointV_tYaFTu Referenced from: <BAD7A699-FB4E-3D0E-8CD4-45CC9FC3D5E5> /Users/sereza/Library/Developer/CoreSimulator/Devices/B64EAF39-0DD9-49EC-A3F7-69675C94B8BE/data/Containers/Bundle/Application/F4E30E86-ED4D-4748-AB99-434208D55483/VisionKitChecker.app/VisionKitChecker Expected in: <F05E3A17-D74A-3EE2-BC8D-DDCC23E48707> /Library/Developer/CoreSimulator/Volumes/iOS_20E247/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.4.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/VisionKit.framework/VisionKit Here is enough code to produce this crash. Please note that this code never gets called. It is enough that it exists in the project: import VisionKit @MainActor final class LiftHelper: ObservableObject { func doSomething() async throws { let interaction = ImageAnalysisInteraction() let _ = try await interaction.image(for: []) } }

Does anyone know which control is used to automatically recognize objects in photos and achieve the function of cutout by right-clicking the mouse?

I would like to know what is the global path of the Vision Pro file system. For instance, if I put a file called example.pdf inside "On My Apple Vision Pro" what would be the global path for that file? "On My Apple Vision Pro/user_name/example.pdf" or "/example.pdf" or "/username/example.pdf" and so on. I tried to search about it but I didn't found no official source about it. Thanks in advance!

有人知道这个鼠标点击右键自动识别照片中的对象然后可以实现抠图的功能用的是哪个控件吗？

手机系统相册中有个长按识别对象的功能，这个功能在苹果开发中叫做什么，我应该使用哪个控件才能拥有这个功能？

There is a long press recognition feature in the photo album of the mobile phone system. What is this feature called in Apple development, and which control should I use to have this feature?

I'm looking for a solution to take a picture or point the camera at a piece of clothing and match that image with an image the user has stored in my app. I'm storing the data in a Core Data database as a Binary Data object. Since the user also takes the pictures they store in the database I think I cannot use pre-trained Core ML models. I would like the matching to be done on device if possible instead of going to an external service. That will probably describe the item based on what the AI sees, but then I cannot match the item with the stored images in the app. Does anyone know if this is possible with frameworks as Vision or VisionKit?

I try to use the new VNCalculateImageAestheticsScoresRequest API. Code is compiling and running but delivers the same result for every image Xcode 16 Beta 2 Simulator Did I missing anything ?

What is the best way to demonstrate or create 2D video to demonstrate an immersive video app? So far I've shared the AVP to my desktop Mac and screen captured the resulting view. Rather shaky at times. With visionOS 2.0 beta (2) is there a better way? Thanks, David

Hello, I want to capture video from Vision Pro in the Vision OS app. I am referring to the (https://developer.apple.com/videos/play/wwdc2024/10139/) Apple video and their code. step like below import ARKit com.apple.developer.arkit.main-camera-access.allow = true in info.plist Do below code func loadCameraFeed() async { // Main Camera Feed Access Example let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions:[.left]) let cameraFrameProvider = CameraFrameProvider() var arKitSession = ARKitSession() var pixelBuffer: CVPixelBuffer? await arKitSession.queryAuthorization(for: [.cameraAccess]) do { try await arKitSession.run([cameraFrameProvider]) } catch { return } guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]) else { return } print(cameraFrameUpdates) for await cameraFrame in cameraFrameUpdates { print(cameraFrame) guard let mainCameraSample = cameraFrame.sample(for: .left) else { continue } pixelBuffer = mainCameraSample.pixelBuffer } } I want to convert "pixelBuffer" into video streaming and show it in a frame like iOS. Please guide me on how to achieve my next step. I am blank after this code.

I am new to visionOS development, just slowly figuring out the difference in immersion styles to figure out how I want my app to behave. It seems that when you use a progressive immersive space the minimum immersion level (set via the digital crown) is not 0? Meaning, there is no way to go from mixed to full by using the Digital Crown. Even when I try to set it to 0 (such as in the Destination Video sample), it pops back up to around 30-40%, and I always see the background. Is this expected behavior, or are there some settings that allow me to change this minimum immersion level? Further, in the video 'Meet ARKit for spatial computing', it is stated that to get access to ARKit tracking data you must use a 'Full Space', not the 'Shared Space'. This wording is confusing to me. Is an ImmersiveSpace set to the .mixed (or .progressive) immersion style still a 'Full Space' (because it isn't in the shared space, with other apps)? OR, is ARKit only available in an ImmersiveSpace with the .full immersion style? Just feels like maybe 'full' is being used in two different ways here... Thanks in advance, -pj

In our app, we needed to use visionkit framework to lift up the subject from an image and crop it. Here is the piece of code: if #available(iOS 17.0, *) { let analyzer = ImageAnalyzer() let analysis = try? await analyzer.analyze(image, configuration: self.visionKitConfiguration) let interaction = ImageAnalysisInteraction() interaction.analysis = analysis interaction.preferredInteractionTypes = [.automatic] guard let subject = await interaction.subjects.first else{ return image } let s = await interaction.subjects print(s.first?.bounds) guard let cropped = try? await subject.image else { return image } return cropped } But the s.first?.bounds always returns a cgrect with all 0 values. Is there any other way to get the position of the cropped subject? I need the position in the image from where the subject was cropped. Can anyone help?

I faced a problem during development that I could not scan Code39 barcode with iPad using Vision. A sample label I used for test has multiple Code39 barcode on it and I could scan almost all barcodes except for specific one. And when I use conventional barcode scanner and free apps to scan barcode, I could scan the barcode with no problem. I failed to scan the barcode only when I use Vision function. Has anyone faced similar situation? Do you know the cause why specific barcode could not be scanned with iPad with Vision?
