I tried to show spatial photo on my application by swiftUI's Image but it just show flat version of it even I Use Vision Pro, so, how can I show spatial photo to users, does there any options for this?

I found some snapshot API in developer documents, like blows: RealityKit / Views and attachments / ARView / /snapshot(saveToHDR:completion:) SceneKit / SCNView / snapshot() Is there a similar API in visionOS？and if not, how can I implement snapshot for realityview and usdz?

I have been experimenting with the Hello World sample app from https://developer.apple.com/documentation/visionos/world and I came across behavior that appears inconsistent with user-facing documentation describing the device controls at https://support.apple.com/en-gb/guide/apple-vision-pro/tan1e2a29e00/visionos I tried pressing simulator's "Home" button while "Objects in Orbit" immersive space was presented alongside with the main application window. According to user documentation, pressing Digital Crown should take the user directly to Home View. In my test a single press only dismissed the immersive space, I needed another press to "exit" the app and go to Home View. Is this behavior expected? I am assuming that "Home" button in the simulator behaves as if the user pressed Digital Crown on the device, I don't have access to the actual hardware.

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://developer.apple.com/documentation/realitykit/unlitmaterial/init(applypostprocesstonemap:) Is it possible to do the same for CustomMaterial? I tried initializing a CustomMaterial based on an UnlitMaterial where tone mapping is disabled, like so: let unlitMat = UnlitMaterial(applyPostProcessToneMap: false) let customMaterial = try CustomMaterial( from: unlitMat, surfaceShader: surfaceShader, geometryModifier: geometryModifier ) but that does not seem to work. The colors of my texture still look altered in comparison to a plain UnlitMaterial or a ShaderGraphMaterial where its disabled. Any hints? Thank you!

Can I apply .scrollInputBehavior(.enabled, for: .look) to a WebView (wrapped UIViewRepresentable) in a visionOS 26 app? I tried it myself, but I couldn't do it, so I would like to know if there is any way to do this. Best regards.

In Vision OS app, I have two types of windows: Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content. Immersive Space Window – This opens only when a user starts streaming or playing a video. Issue: When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting from immersive space. However, this causes the app to restart instead of resuming from its previous state. Desired Behavior: I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting. Attempts & Challenges: Tried managing opacity, visibility but none worked as expected. Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground. Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.

I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like: let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics) This is now giving a compiler error: Type of expression is ambiguous without a type annotation I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.: let naturalSize = try? await videoTrack.load(.naturalSize) let formatDescriptions = try? await videoTrack.load(.formatDescriptions) let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)

After re-launching the immersive space in my app 5-10 times, the WorldTrackingProvider stops working. Only restarting the app will allow it to start working again. Only on device, not the simulator. I get these errors when it happens: The device_anchor can only be queried when the world tracking provider is running.

Hello, For GuessTogether source code, it seems like the code assumes that you're already in a FaceTime call before pressing the custom SharePlay button (labeled "Play Guess Together"). If not already on a FaceTime call, my Apple Vision Pro and the visionOS simulator both do nothing after throwing warnings. Is this intended behavior? If so, how do I make it so that pressing the button can also initiate FaceTime calls? Is this allowed? Thank you!

Hello all, I saw this interesting VisionOS app: https://apps.apple.com/us/app/splitscreen-multi-display/id6478007837 I was wondering if there was any documentation on the Swift APIs that were used to create this app.

当我进入混合空间时，出现一个模型，但模型后面有一个 windowGroup，无法完全查看。如果我想点击进入 mix 空间，我需要使用代码将 windowGroup 移动到另一个位置，而不是手动移动 ![]（“https://developer.apple.com/forums/content/attachment/0471ead0-4c74-43a7-9ecc-12e67e81cec6” “title=WechatIMG31.jpg;宽度=915;高度=777”）

It's much easier to use custom material to bridge metal shader onto Reality model than using LowLevelTexture does the same thing. Why VisionOS doesn't support this material:

Has anyone had success with MeshInstancesComponent? I tried to follow the sample code from What's New in RealityKit but it wouldn't compile. I was able to use one of the init overloads to get it to compile, but using it crashes both my device and the simulator. Even with one instance.

Hello, I am currently working on a Unity project for the Apple Vision Pro. I would like to have people passing in front of the virtual objects occlude the virtual objects that are behind. Something similar to this: https://developer.apple.com/documentation/arkit/occluding-virtual-content-with-people I could unfortunately not find any documentation about this. Is it possible to implement body segmentation or occlusion on the Apple Vision Pro? If it's not currently supported, are there plans to add it? Any ideas on how to achieve this with existing tools? Thanks! Mehdi

I have tested the MagnifyGesture code below on multiple devices: Vision Pro - working iPhone - working iPad - working macOS - not working In Reality Composer Pro, I have also added the below components to the test model entity: Input Target Collision For macOS, I tried the touchpad pinch gesture and mouse scroll wheel, but neither approach works. How to resolve this issue? Thank you. import SwiftUI import RealityKit import RealityKitContent struct ContentView: View { var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) } } .gesture(MagnifyGesture() .targetedToAnyEntity() .onChanged(onMagnifyChanged) .onEnded(onMagnifyEnded)) } func onMagnifyChanged(_ value: EntityTargetValue<MagnifyGesture.Value>) { print("onMagnifyChanged") } func onMagnifyEnded(_ value: EntityTargetValue<MagnifyGesture.Value>) { print("onMagnifyEnded") } }

Currently I am using mixed style immersive view to place both my WindowView(plain style) and ImmersiveView content together. The issue is that the rendering depth testing may always let the virtual content block my normal WindowView. Is it possible to manually set windowedVIew always displays in the front of my virtual view in mixed style immersion? (I know modelSortGroup but it doesn't quite fits here) Or if I can dynamically change the .progressive value when the immersive space is open (set the value to zero means .mixed itself right?)

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 visionOS. I saw that there is a new way to add SwiftUI View attachments in my RealityView, what advantages does this have over the old way? Attachments can now be added directly to your entities with ViewAttachmentComponent. The removes the need to declare your attachments upfront in your RealityView initializer and then add those attachments as child entities. The new approach provides greater flexibility. Canyon Crosser and Petite Asteroids both utilize the new approach. ManipulationComponent looks really cool! Right now my app has a series of complicated custom gestures. What gestures does it handle for me exactly, and are there any situations where I should prefer my own custom gestures? ManipulationComponent provides natural interaction with virtual objects. It seamlessly handles translation and rotation. You can easily add manipulation to a SwiftUI view like Model3D with the manipulable view modifier. The new Object Manipulation API is great for most apps, and is a breeze to implement, but sometimes you might want a more custom feel, and that’s ok! Custom gestures are still fully supported for that scenario. I saw that there is a new API to also access the right main camera. What can I do with this? Correct, in visionOS 26, you can access the left and right main cameras. You can even access them simultaneously as a stereo pair. Camera access still requires a managed entitlement and an enterprise license, see Accessing the main camera for more details about those requirements. More computer vision and machine learning use-cases are unlocked with access to both cameras, we are excited to see what you will do! What do I need to do to add spatial accessory input for my app? First, use the GameController framework to establish a connection with the spatial accessory, and then listen for events from the controller. Then, you can use either RealityKit, ARKit, or a combination of both to track the accessory, anchor virtual content to it, and fine tune the accessory interaction with the content in your app. For more details, check out Discovering and tracking spatial game controllers and styli. By far, the most difficulty with implementing visionOS apps is SwiftUI window management…placing, opening, closing, etc. Are there any improvements to window management in visionOS 26? Yes! We recommend watching Set the scene with SwiftUI in visionOS. You can use the defaultLaunchBehavior to choose whether a particular window is presented (or suppressed) at launch. You can also prevent a window like a secondary toolbar from launching as the initial window using .restorationBehavior(.disabled). Adopting best practices for persistent UI provides a great overview of SwiftUI window management on visionOS. As for placing windows, there is still no API for an app to specify the placement of its windows other than relative placement. If that is a feature you are interested in, please file an enhancement request for it using Feedback Assistant! How to get access to the Enterprise API? First, request the entitlement and license through your Apple Developer or enterprise account. Once these have been granted, include the license and entitlement in your project. Then you can build, test, and distribute as an in-house app.

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) } }

Hello, I'm currently trying to make a collaborative app. But it just works only on Reality View, when I tried to use Compositor Layer like below, the personas disappeared. ImmersiveSpace(id: "ImmersiveSpace-Metal") { CompositorLayer(configuration: MetalLayerConfiguration()) { layerRenderer in SpatialRenderer_InitAndRun(layerRenderer) } } Is there any potential solution too see Personas in Metal view? Thanks in advance!
