I started a new project using RealityKit and RealityView, intended as an AR app on iPhone and iPad, but eventually VisionOS as well. I'm challenged because I find much of the recent documentations, WWDC videos, etc, include features that are VisionOS only. Right now, I would simply like to create some gesture functionality that is similar to AR Quick Look defaults, meaning drag to reposition, two fingers to rotate or zoom. In the past, this would be implemented with something like: arView.installGestures([.all], for: entity) however, with RealityView I don't know how (or if possible) to access an ARView. In RealityKit, I have found this doc: https://developer.apple.com/documentation/realitykit/transforming-realitykit-entities-with-gestures However, many of the features in that posting are VisionOS only, and I've found no good documentation on the topic that is specific or at least compatible with iOS. I know reverting to an ARView is an option, but I want to use RealityView if at all possible as I see it as more forward-looking.

Hi, are we allowed to push the default support in Package.swift up to iOS 18 to allow for the latest APIs? And with the terms of the competition, can we use stock 3D USDZ assets? Thank you!

Hi everyone, I've been exploring an idea that involves using virtual light sources in VisionOS/RealityKit to interact with real-world objects. Specifically, I'd like to simulate a scenario where a virtual spotlight or other light source casts light or shadows onto real-world environments, creating the effect of virtual lighting interacting with physical surroundings. Is this currently feasible within VisionOS/RealityKit? Thank you!

I have Mac mini M4 with 16GB memory, the Xcode is 16.1, when I test my Vision Pro App with the Simulator, it is very slow and system shows the memory is under the high pressure. How do I run/test/debug the application on Vision Pro directly? Tried to add my Vision Pro to my developer account, it didn't work due to cannot find UDID, when I hook the USB to the battery, it only shows Battery device ID.

I want to create a screenshot (static image) of the current view on the Apple Vision Pro using written code in visionOS. Unfortunately, I currently can’t find a way to achieve this. The only option I’ve found so far is through Reality Composer Pro. However, since I want to accomplish this directly through code, this approach is not an option for me.

Is there any way to detect if an entity is being looked at in a RealityView. I know it is possible to add a "HoverEffectComponent()" which will highlight the entity a little when you gaze on it, but there doesn't seem to be any way to call a function from this. There is also no GazeGesture or anything similar.

In visionOS, once an immersive space is opened, the background color is solid black, is it possible to make this background transparent? FYI, The Immersive spaces on visionOS uses Compositor Services for drawing 3D content.

If I update vision pro size then textfield and button are not update as per its new size. Its working on some scren but not in some screen. Please refer below screenshot for your reference,

Hi team I don't know from this error has popped up any suggestions please Thanks Zippy Games

Hi, I am trying to update what entities are visible in my RealityView. After the SwiftData set is updated, I have to restart the app for it to appear in the RealityView. Also, the RealityView does not close when I move to a different tab. It keeps everything on and tracking, leaving the model in the same location I left it. import SwiftUI import RealityKit import MountainLake import SwiftData struct RealityLakeView: View { @Environment(\.modelContext) private var context @Query private var items: [Item] var body: some View { RealityView { content in print("View Loaded") let lakeScene = try? await Entity(named: "Lake", in: mountainLakeBundle) let anchor = AnchorEntity(.plane(.horizontal, classification: .any, minimumBounds: SIMD2<Float>(0.2, 0.2))) @MainActor func addEntity(name: String) { if let lakeEntity = lakeScene?.findEntity(named: name) { // Add the Cube_1 entity to the RealityView anchor.addChild(lakeEntity) } else { print(name + "entity not found in the Lake scene.") } } addEntity(name: "Island") for item in items { if(item.enabled) { addEntity(name: item.value) } } // Add the horizontal plane anchor to the scene content.add(anchor) content.camera = .spatialTracking } placeholder: { ProgressView() } .edgesIgnoringSafeArea(.all) } } #Preview { RealityLakeView() }

We use Unity6+VisonOS2.2 to develop an MR Application. App Mode: RealityKit with PolySpatial, In the actual test, we found that when my moving position is more than 80~100 meters away from the starting position of the application, my current position will be reset to Vector.zero, which will cause my application experience to be very bad. Is anyone experiencing the same problem? Is there a solution?

In visionOS, there are existing modifiers that can completely conceal the hands. However, I am interested in learning how to achieve the effect of only one hand disappearing while the other hand remains visible. .upperLimbVisibility(.hidden)

Hi, since RealityKit 4 now supports Blend Shapes I was wondering if there are any workflow or tooling recommendations to bake/export them into a USDZ. Are Blender or Cinema4D capable to do that out of the box? Should we look into NVIDIA omniverse (https://docs.omniverse.nvidia.com/connect/latest/blender/manual.htm) So far this topic seems very sparsely documented and I would appreciate any hints. Thank you!

I have a MeshResource and I would like to create a collision component from it. let childBounds = child.visualBounds(relativeTo: self) var childShape: ShapeResource do { // Crashed by the following line instead of throwing a Swift Error childShape = try await ShapeResource.generateConvex(from: childModel.mesh); } catch { childShape = ShapeResource.generateBox(size: childBounds.extents) childShape = childShape.offsetBy(translation: childBounds.center) } Based on this document: https://developer.apple.com/documentation/realitykit/shaperesource/generateconvex(from:)-6upj9 Will throw an error if mesh does not define a nonempty convex volume. For example, will fail if all the vertices in mesh are coplanar. But, the method crashes the app instead of throwing a Swift error Incident Identifier: 35CD58F8-FFE3-48EA-85D3-6D241D8B0B4C CrashReporter Key: FE6790CA-6481-BEFD-CB26-F4E27652BEAE Hardware Model: Mac15,11 ...

Hello, I am currently developing a Vision Pro VR application with Unreal Engine 5.5. Is it possible to interact with objects (grabbing, clicking on buttons)? I cannot find any information on this. Thank you.

I’m working on an iOS app that needs to measure the area of planes or surfaces, like the length and width of objects, just like the Apple Measure app does. I’ve been exploring ARKit, but I’m curious if there are any APIs or techniques that can help automate the process of detecting and measuring planes. Specifically, I’m looking for a way to automatically detect and measure planes (e.g., from a top-down view). For example: Measuring a box width and length. I have attached a screenshot and a video of the Apple Measure App doing it. Does Apple provide any tools or APIs for this, or are there any best practices I should know about? I’d love to hear from anyone who’s tackled something similar. Video: https://drive.google.com/file/d/1BxM7fIbFxsCsYwY7w8ZxIeq_4WTGkkwA/view?usp=drive_link

I am getting the error "Initializing hosting entity without a context" in the console when I build and run my game in XCode 16.0 beta, targeting Vision Pro OS 2.0 (22N5252n). Not sure where the error is originating.

I would like to integrate the object capture API with a ML model for analysis. So, i will need to get the current frame into CG images for further process. Thanks in advance !

I'm developing an app in which I need to render pictures and contain some models in a RealityView. I want to set up a camera, intercept virtual content through the camera, and save it as an image.

I implemented a ShaderGraphMaterial and tried to load it from my usda scene by ShaderGraphMaterial.init(name: in: bundle). I want to dynamically set TextureResource on that material, so I wanted to expose texture as Uniform Input of a ShaderGraphMaterial. But obviously RCP's Shader Graph doesn't support Texture input as parameter as the image shows: And from the code level, ShaderGraphMaterial also didn't expose a way to set TexturesResources neither. Its parameterNames shows an empty array if I didn't set any custom input params. The texture I get is from my backend so it really cannot be saved into a file and load it again (that would be too weird). Is there something I am missing?
