Apple published a set of examples for using system gestures to interact with RealityKit entities. I've been using DragGesture a lot in my apps and noticed an issue when using it in an immersive space. When dragging an entity, if I turn my body to face another direction, the dragged entity does not stay relative to my hand. This can lead to situations where the entity is pulled very close to me, or pushed far way, or even ends up behind me. In the examples linked above, there are two versions of how they use drag. handleFixedDrag: This is similar to what I'm doing now. It uses the value from value.gestureValue.translation3D as the basis for the drag handlePivotDrag: This version aims to solve the problem I described above by using value.inputDevicePose3D as the basis of the gesture. I've tried the example from handlePivotDrag, but it has one limitation. Using this version, I can move the entity around me as if it were on the inside of an arc or sphere. However, I can no longer move the entity further or closer. It stays within a similar (though not exact) distance relative to me while I drag. Is there a way to combine these concepts? Ideally, I would like to use a gesture that behaves the same way that visionOS windows do. When we drag windows, I can move them around relative to myself, pull them closer, push them further, all while avoiding the issues described above. Example from handleFixedDrag mutating private func handleFixedDrag(value: EntityTargetValue<DragGesture.Value>) { let state = EntityGestureState.shared guard let entity = state.targetedEntity else { fatalError("Gesture contained no entity") } if !state.isDragging { state.isDragging = true state.dragStartPosition = entity.scenePosition } let translation3D = value.convert(value.gestureValue.translation3D, from: .local, to: .scene) let offset = SIMD3<Float>(x: Float(translation3D.x), y: Float(translation3D.y), z: Float(translation3D.z)) entity.scenePosition = state.dragStartPosition + offset if let initialOrientation = state.initialOrientation { state.targetedEntity?.setOrientation(initialOrientation, relativeTo: nil) } } Example from handlePivotDrag mutating private func handlePivotDrag(value: EntityTargetValue<DragGesture.Value>) { let state = EntityGestureState.shared guard let entity = state.targetedEntity else { fatalError("Gesture contained no entity") } // The transform that the pivot will be moved to. var targetPivotTransform = Transform() // Set the target pivot transform depending on the input source. if let inputDevicePose = value.inputDevicePose3D { // If there is an input device pose, use it for positioning and rotating the pivot. targetPivotTransform.scale = .one targetPivotTransform.translation = value.convert(inputDevicePose.position, from: .local, to: .scene) targetPivotTransform.rotation = value.convert(AffineTransform3D(rotation: inputDevicePose.rotation), from: .local, to: .scene).rotation } else { // If there is not an input device pose, use the location of the drag for positioning the pivot. targetPivotTransform.translation = value.convert(value.location3D, from: .local, to: .scene) } if !state.isDragging { // If this drag just started, create the pivot entity. let pivotEntity = Entity() guard let parent = entity.parent else { fatalError("Non-root entity is missing a parent.") } // Add the pivot entity into the scene. parent.addChild(pivotEntity) // Move the pivot entity to the target transform. pivotEntity.move(to: targetPivotTransform, relativeTo: nil) // Add the targeted entity as a child of the pivot without changing the targeted entity's world transform. pivotEntity.addChild(entity, preservingWorldTransform: true) // Store the pivot entity. state.pivotEntity = pivotEntity // Indicate that a drag has started. state.isDragging = true } else { // If this drag is ongoing, move the pivot entity to the target transform. // The animation duration smooths the noise in the target transform across frames. state.pivotEntity?.move(to: targetPivotTransform, relativeTo: nil, duration: 0.2) } if preserveOrientationOnPivotDrag, let initialOrientation = state.initialOrientation { state.targetedEntity?.setOrientation(initialOrientation, relativeTo: nil) } }

Hi, would love for your help in that matter. I try to get the position in space of two QR codes to make an alignment to their positions in space. The detection shows that the QR codes position is always 0,0,0 and I don't understand why. Here's my code: import SwiftUI import RealityKit import RealityKitContent struct AnchorView: View { @ObservedObject var qrCoordinator: QRCoordinator @ObservedObject var coordinator: ImmersiveCoordinator let qrName: String @Binding var startQRDetection: Bool @State private var anchor: AnchorEntity? = nil @State private var detectionTask: Task<Void, Never>? = nil var body: some View { RealityView { content in // Add the QR anchor once (must exist before detection starts) if anchor == nil { let imageAnchor = AnchorEntity(.image(group: "QRs", name: qrName)) content.add(imageAnchor) anchor = imageAnchor print("📌 Created anchor for \(qrName)") } } .onChange(of: startQRDetection) { enabled in if enabled { startDetection() } else { stopDetection() } } .onDisappear { stopDetection() } } private func startDetection() { guard detectionTask == nil, let anchor = anchor else { return } detectionTask = Task { var detected = false while !Task.isCancelled && !detected { print("🔎 Checking \(qrName)... isAnchored=\(anchor.isAnchored)") if anchor.isAnchored { // wait a short moment to let transform update try? await Task.sleep(nanoseconds: 100_000_000) let worldPos = anchor.position(relativeTo: nil) if worldPos != .zero { // relative to modelRootEntity if available var posToSave = worldPos if let modelEntity = coordinator.modelRootEntity { posToSave = anchor.position(relativeTo: modelEntity) print("converted to model position") } else { print("⚠️ modelRootEntity not available, using world position") } print("✅ \(qrName) detected at position: world=\(worldPos) saved=\(posToSave)") if qrName == "reanchor1" { qrCoordinator.qr1Position = posToSave let marker = createMarker(color: [0,1,0]) marker.position = .zero // sits directly on QR marker.position = SIMD3<Float>(0, 0.02, 0) anchor.addChild(marker) print("marker1 added") } else if qrName == "reanchor2" { qrCoordinator.qr2Position = posToSave let marker = createMarker(color: [0,0,1]) marker.position = posToSave // sits directly on QR marker.position = SIMD3<Float>(0, 0.02, 0) anchor.addChild(marker) print("marker2 added") } detected = true } else { print("⚠️ \(qrName) anchored but still at origin, retrying...") } } try? await Task.sleep(nanoseconds: 500_000_000) // throttle loop } print("🛑 QR detection loop ended for \(qrName)") detectionTask = nil } } private func stopDetection() { detectionTask?.cancel() detectionTask = nil } private func createMarker(color: SIMD3<Float>) -> ModelEntity { let sphere = MeshResource.generateSphere(radius: 0.05) let material = SimpleMaterial(color: UIColor( red: CGFloat(color.x), green: CGFloat(color.y), blue: CGFloat(color.z), alpha: 1.0 ), isMetallic: false) let marker = ModelEntity(mesh: sphere, materials: [material]) marker.name = "marker" return marker } }

hi, I'm trying to create a virtual movie theater, but after running computeDiffuseReflectionUVs.py and applying attenuation map, I noticed the light falloff effect just covers over the objects. I used apple provided attenuation map (did not specify the attenuation map name on python script) with sample size of 6000. I thought the python script would calculate vertices and create shadow for, say, back of the chairs. Am I understanding this wrong?

Hi, I'm developing an app for Vision Pro using Xcode, while updating the latest update, things that worked in my app suddenly didn't. in my app flow I'm tapping spheres to get their positions, from some reason I get an offset from where I tap to where a marker on that position is showing up. here's the part of code that does that, and a part that is responsible for an alignment that happens afterwards: func loadMainScene(at position: SIMD3) async { guard let content = self.content else { return } do { let rootEntity = try await Entity(named: "surgery 16.09", in: realityKitContentBundle) rootEntity.scale = SIMD3<Float>(repeating: 0.5) rootEntity.generateCollisionShapes(recursive: true) self.modelRootEntity = rootEntity let bounds = rootEntity.visualBounds(relativeTo: nil) print("📏 Model bounds: center=\(bounds.center), extents=\(bounds.extents)") let pivotEntity = Entity() pivotEntity.addChild(rootEntity) self.pivotEntity = pivotEntity let modelAnchor = AnchorEntity(world: [1, 1.3, -0.8]) modelAnchor.addChild(pivotEntity) content.add(modelAnchor) updateModelOpacity(0.5) self.modelAnchor = modelAnchor rootEntity.visit { entity in print("👀 Entity in model: \(entity.name)") if entity.name.lowercased().hasPrefix("focus") { entity.generateCollisionShapes(recursive: true) entity.components.set(InputTargetComponent()) print("🎯 Made tappable: \(entity.name)") } } print("✅ Model loaded with collisions") guard let sphere = placementSphere else { return } let sphereWorldXform = sphere.transformMatrix(relativeTo: nil) var newXform = sphereWorldXform newXform.columns.3.y += 0.1 // move up by 20 cm let gridAnchor = AnchorEntity(world: newXform) self.gridAnchor = gridAnchor content.add(gridAnchor) let baseScene = try await Entity(named: "Scene", in: realityKitContentBundle) let gridSizeX = 18 let gridSizeY = 10 let gridSizeZ = 10 let spacing: Float = 0.05 let startX: Float = -Float(gridSizeX -

SharePlay objects are not placed in the same place in the same space. I hope they can be placed in the same place. （Vision Pro）

Hi, I am a new developer. I want to add articulated objects and deformable objects into my AR game. I haven't found any tutorial on this, I hope to interact with these objects. Please let me know if this is available in visionOS.

We have successfully obtained the permissions for "Main Camera access" and "Passthrough in screen capture" from Apple. Currently, the video streams we have received are from the physical world and do not include the digital world. How can we obtain video streams from both the physical and digital worlds? thank you!

I have my immersive space set up like: ImmersiveSpace(id: "Theater") { ImmersiveTeleopView() .environment(appModel) .onAppear() { appModel.immersiveSpaceState = .open } .onDisappear { appModel.immersiveSpaceState = .closed } } .immersionStyle(selection: .constant(appModel.immersionStyle.style), in: .mixed, .full) Which allows me to set the immersive style while in the space (from a Picker on a SwiftUI window). The scene responds correctly but a lot of the functionality of my immersive space is gone after the change in style; in that I am no longer able to enable/disable entities (which I also have a toggles for in the SwiftUI window). I have to exit and reenter the immersive space to regain the ability to change the enabled state of my entities. My appModel.immersionStyle is inspired by the Compositor-Services demo (although I am using a RealityView) listed in https://developer.apple.com/documentation/CompositorServices/interacting-with-virtual-content-blended-with-passthrough and looks like this: public enum IStyle: String, CaseIterable, Identifiable { case mixedStyle, fullStyle public var id: Self { self } var style: ImmersionStyle { switch self { case .mixedStyle: return .mixed case .fullStyle: return .full } } } /// Maintains app-wide state @MainActor @Observable class AppModel { // Immersion Style public var immersionStyle: IStyle = .mixedStyle

After implementing the method of obtaining video streams discussed at WWDC in the program, I found that the obtained video stream does not include digital models in the digital space or related videos such as the program UI. I would like to ask how to obtain a video stream or frame that contains only the physical world? let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions:[.left]) let cameraFrameProvider = CameraFrameProvider() var arKitSession = ARKitSession() var pixelBuffer: CVPixelBuffer? var cameraAccessStatus = ARKitSession.AuthorizationStatus.notDetermined let worldTracking = WorldTrackingProvider() func requestWorldSensingCameraAccess() async { let authorizationResult = await arKitSession.requestAuthorization(for: [.cameraAccess]) cameraAccessStatus = authorizationResult[.cameraAccess]! } func queryAuthorizationCameraAccess() async{ let authorizationResult = await arKitSession.queryAuthorization(for: [.cameraAccess]) cameraAccessStatus = authorizationResult[.cameraAccess]! } func monitorSessionEvents() async { for await event in arKitSession.events { switch event { case .dataProviderStateChanged(_, let newState, let error): switch newState { case .initialized: break case .running: break case .paused: break case .stopped: if let error { print("An error occurred: \(error)") } @unknown default: break } case .authorizationChanged(let type, let status): print("Authorization type \(type) changed to \(status)") default: print("An unknown event occured \(event)") } } } @MainActor func processWorldAnchorUpdates() async { for await anchorUpdate in worldTracking.anchorUpdates { switch anchorUpdate.event { case .added: //检查是否有持久化对象附加到此添加的锚点- //它可能是该应用程序之前运行的一个世界锚。 //ARKit显示与此应用程序相关的所有世界锚点 //当世界跟踪提供程序启动时。 fallthrough case .updated: //使放置的对象的位置与其对应的对象保持同步 //世界锚点，如果未跟踪锚点，则隐藏对象。 break case .removed: //如果删除了相应的世界定位点，则删除已放置的对象。 break } } } func arkitRun() async{ do { try await arKitSession.run([cameraFrameProvider,worldTracking]) } catch { return } } @MainActor func processDeviceAnchorUpdates() async { await run(function: self.cameraFrameUpdatesBuffer, withFrequency: 90) } @MainActor func cameraFrameUpdatesBuffer() async{ guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]),let cameraFrameUpdates1 = cameraFrameProvider.cameraFrameUpdates(for: formats[1]) else { return } for await cameraFrame in cameraFrameUpdates { guard let mainCameraSample = cameraFrame.sample(for: .left) else { continue } self.pixelBuffer = mainCameraSample.pixelBuffer } for await cameraFrame in cameraFrameUpdates1 { guard let mainCameraSample = cameraFrame.sample(for: .left) else { continue } if self.pixelBuffer != nil { self.pixelBuffer = mergeTwoFrames(frame1: self.pixelBuffer!, frame2: mainCameraSample.pixelBuffer, outputSize: CGSize(width: 1920, height: 1080)) } } }

I need to loop my videoMaterial and I don't know how to make it happen in my code. I have included an image of my videoMaterial code. Any help making this happen with be greatly appreciated. Thank you, Christopher

Hi there I'm using Reality Composer Pro to anchor virtual content to a .referenceobject. However moving the referenceobject quickly causes tracking to stop. (I know this is a limitation and I am trying to embrace it as a feature) Is there a way to play a USDZ animation at the last known location, after detecting that the reference object is no longer tracked? is it possible to set this up in Reality Composer pro? I'm trying to get the USDZ to play before the Virtual Content disappears (due to reference object not being located). So that it smooths out the vanishing of the content. Nearly everything is set up in Reality Composer pro with my immersive.scene just adding virtual content to the reference object which anchors it in the RCP Scene, so my immersive view just does this - if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) & this .onAppear { appModel.immersiveSpaceState = .open } .onDisappear { appModel.immersiveSpaceState = .closed } I have tried Using SpatialTracking & WorldTrackingProvider, but I'm still quite new to Swift and coding in general so im unsure how to implement in conjunction with my RCP scene and/or if this is the right way to go about it. Also I have implemented this at the beginning of object tracking. All I had to do was add a onAppear behavior to the object to play a USDZ and that works. Doing it for disappearing (due to loss of reference object) seems to be a lot harder.

My app is getting video from UVC device, and I wish to display it in an Immersive Space. But when I open Immersive Space, the UVC capture will just stop.AI said it's due to confliction in Camera pipeline. But I don't really understand, I don't need to use any on device camera, why it conflict with my UVC...

Hi, I'm encountering an issue in our app that uses RoomPlan and ARsession for scanning. After prolonged use—especially under heavy load from both the scanning process and other unrelated app operations—the iPhone becomes very hot, and the following warning begins to appear more frequently: "ARSession <0x107559680>: The delegate of ARSession is retaining 11 ARFrames. The camera will stop delivering camera images if the delegate keeps holding on to too many ARFrames. This could be a threading or memory management issue in the delegate and should be fixed." I was able to reproduce this behavior using Apple’s RoomPlanExampleApp, with only one change: I introduced a CPU-intensive workload at the end of the startSession() function: DispatchQueue.global().asyncAfter(deadline: .now() + 5) { for i in 0..<4 { var value = 10_000 DispatchQueue.global().async { while true { value *= 10_000 value /= 10_000 value ^= 10_000 value = 10_000 } } } } I suspect this is some RoomPlan API problem that's why a filed an feedback: 17441091

Hi, I am in the process of implementing SharePlay into our app. The shared experience opens an Immersive Space and we set systemCoordinator.configuration.supportsGroupImmersiveSpace = true Now visionOS establishes a shared coordinate space for the immersive space. From the docs: To achieve consistent positioning of RealityKit entities across multiple devices in an immersive space during a SharePlay session There are cases where we want to position content in front of the user (independent of the shared session, and for each user individually). Normally to do that we use the transform retrieved via worldTrackingProvider.queryDeviceAnchor.originFromAnchorTransform to position content in front of the user (plus some Z Offset and smooth interpolation). This works fine in non-SharePlay instances and the device transform is where I would expect it to be but during the FaceTime call deviceAnchor.originFromAnchorTransform seems to use the shared origin of the immersive space and then I end up with a transform that might be offset. Here is a video of the issue in action: https://streamable.com/205r2p The blue rect is place using AnchorEntity(.head, trackingMode: .continuous). This works regardless of the call and the entity is always placed based on the head position. The green rect is adjusted on every frame using the transform I get from worldTrackingProvider.queryDeviceAnchor. As you can see it's offset. Is there any way I can query query this transform locally for the user during a FaceTime call? Also I would like to know if it's possible to disable this automatic entity transform syncing behavior? Setting entity.synchronization = nil results in the entity not showing up at all. https://developer.apple.com/documentation/realitykit/synchronizationcomponent Is SynchronizationComponent only relevant for the legacy MultiPeerConnectivity approach? Thank you!

I believe I have created a videoMaterial and assigned it to a mesh with code I found in the Developer's Documentation but Im getting this error. "Trailing closure passed to parameter of type 'String' that does not accept a closure" I have attached a photo of the code and where the error happens. Any help will greatly be appreciated.

I'm working on a project that uses imageTrackingProvider through ARKit on VisionPro, and I want to detect multiple images(about 5) and show info at the same time. However, I found that it seems only 1 image could be detected by device at one time. And the api of maximumNumberOfTrackedImages doing this seems not available for visionOS but only iOS. Anyone knows possible ways to detect multiple images at the same time on VisionPro?

Hi, I’m trying to configure camera feed in ARKit to be in Apple Log color space. I can change Capture Device’s format to one that has Apple Log and I see one frame being in proper log-gray colors but then all AR tracking stops and tracking state hangs at “initializing”. In other combinations I see error “sensor failed to initialize” and session restarts with default format. I suspect that this is because normal AR capture formats are 420f, whereas ones that have Apple Log are 422. Could someone confirm if it’s even possible to run ARKit session with camera feed in a different pixel format? I’m trying it on iphone 15 pro

I created a new Spatial Rendering App from the template in Xcode 26.0.1. When I run the app, click 'Show Immersive Space' and select my Vision Pro from the pop-up dialog, the content in the dialog flickers (which seems to indicate something crashed) and nothing appears on my Vision Pro. I'm running the released macOS 26.0 (25A354) and visionOS 26.0 (23M336). Filed as FB20397093.

Hi there, I was looking to add a particle emitter to my augmented reality app I'm developing using RealityKit. I'm targeting iOS. I noticed in the documentation for the ParticleEmitterComponent that it looks like iOS 18.0+ is supported, but when I try to use the ParticleEmitterComponent in my code in XCode, I get an error that it isn't found. Furthermore, this StackOverflow post seems to indicate that particle systems are not available for iOS. Would it be possible to get clarification on this?

How do I configure a Unity project for a fully immersive VR app on Apple Vision Pro using Metal Rendering, and add a simple pinch-to-teleport-where-looking feature? I've tried the available samples and docs, but they don't cover this clearly (to me). So far, I've reviewed Unity XR docs, Apple dev guides, and tutorials, but most emphasize spatial apps. Metal examples exist but don't include teleportation. Specifically: visionOS sample "XRI_SimpleRig" – Deploys to device/simulator, but no full immersion or teleport. XRI Toolkit sample "XR Origin Hands (XR Rig)" – Pinch gestures detect, but not linked to movement. visionOS "XR Plugin" sample "Metal Sample URP" – Metal setup works, but static scene without locomotion. I'm new in Unity XR development and would appreciate a simple, standalone scene or document focused only on the essentials for "teleport to gaze on pinch" in VR mode—no extra features. I do have some experience in unreal, world toolkit, cosmo, etc from the 90's and I'm ok with code. Please include steps for: Setting up immersive VR (disabling spatial defaults if needed). Integrating pinch detection with ray-based teleport. Any config changes or basic scripts.
