"Although Xcode generates loading methods for all Reality Composer files in your Xcode project" I do not find this to be true, sadly. Does anyone have any luck or insight on how one can build just a simple MacOS app that will import a scene from a Reality File? The documentation suggests that the simple act of bringing a .Reality File in (What about .realitycomposerpro?) will generate code, but that doesn't seem to happen. The sample code (Spaceship) does not compile for MacOS. I'd really love just the most generic template of an Xcode Project that compiles with a button that pops open a scene., Like the VisionOS default immersive project.

I'm doing a weather app, users can search locations for getting weather, but the problem is, the results only shows locations in my country, not in global. For example, I'm in China, I can't search New York, it just shows nothing. Here's my code: @Observable class SearchPlaceManager: NSObject { var searchText: String = "" let searchCompleter = MKLocalSearchCompleter() var searchResults: [MKLocalSearchCompletion] = [] override init() { super.init() searchCompleter.resultTypes = .address searchCompleter.delegate = self } @MainActor func seachLocation() { if !searchText.isEmpty { searchCompleter.queryFragment = searchText } } } extension SearchPlaceManager: MKLocalSearchCompleterDelegate { func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) { withAnimation { self.searchResults = completer.results } } } Also, I've tried to set searchCompleter.region = MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 0, longitude: 0), span: MKCoordinateSpan(latitudeDelta: 180, longitudeDelta: 360) ), but it doesn't work.

Hello All, We're going to do a scene now, kind of like a time travel door. When the user selects the scene, the user passes through the door to show the current scene. The changes in the middle need to be more natural. It's even better if you can walk through an immersive space... There is very little information now. How can I start doing this? Is there any information I can refer to thanks

After I played the audio for the entity the sound was very low and I wanted to adjust the sound size. No api is found. What should I do if let audio = audioResources { entity.playAudio(audio) }

I’m developing an app using RealityKit and RealityView. On newer iPhones, such as the iPhone 15 Pro, Object Occlusion appears to be enabled by default, which causes 3D entities to be hidden behind real-world objects in the scene. However, I need to disable this behavior to ensure proper rendering of my 3D content. This issue does not occur on older devices like the iPhone 13, where the app works as intended. I haven’t been able to find a solution to explicitly disable object occlusion on the newer devices for RealityView. Any guidance or suggestions to resolve this issue would be greatly appreciated! Thanks!

Hey, I have Enterprise Access on the account and have added the passthrough capability and the entitlement on the main project and the "Broadcast Upload" extension, too. The broadcast works except it returns a black screen. I am attaching some screenshots below of the entitlement file. I have tried searching online to no avail, so any help would be greatly appreciated.

In RealityView, physical components are only applicable to certain solids. How can I simulate the physical effects of water and cloth? enity.components.set(PhysicalComponent)

We have a plane model (basecircle)without physics and rigid body components, and no gestures are implemented. However, when tapped, the model unexpectedly falls into infinity. func fetchEnvResource(){ var simpleMaterial = SimpleMaterial() env = try! Entity.loadModel(named: "bgMain5") env.position += [0,0,-10] envTexture = PhysicallyBasedMaterial() envTextureUnlit = UnlitMaterial() envTexture.baseColor = .init(texture: .init(try! .load(named: "bgMain5"))) envTextureUnlit.color = .init(texture: .init(try! .load(named: "bgMain5"))) env.isEnabled = false let anchor = AnchorEntity(world: [0, 0, -3]) baseCircle = ModelEntity(mesh: .generatePlane(width: 1.5, depth: 1.5, cornerRadius: 0.75), materials: [SimpleMaterial(color: .green, isMetallic: false)]) env.components.set(InputTargetComponent()) baseMaterial = PhysicallyBasedMaterial() baseMaterialUnlit = UnlitMaterial() baseMaterial.baseColor = .init(texture: .init(try! .load(named: "groundTexture"))) baseMaterial.baseColor.tint = UIColor(white: 1.0, alpha: CGFloat(textureOpacity)) baseCircle.model?.materials = [baseMaterial] baseCircle.generateCollisionShapes(recursive: false) baseCircle.components.set(InputTargetComponent()) baseCircle.components[PhysicsBodyComponent.self] = .init(PhysicsBodyComponent(massProperties: .default, mode: .static)) baseCircle.physicsBody = PhysicsBodyComponent( mode: .kinematic ) anchorEntity.addChild(baseCircle) baseCircle.position = [0,0,-3] baseCircle.isEnabled = false let cylinder = ModelEntity(mesh: .generateCylinder(height: 0.2, radius: 0.5), materials: [SimpleMaterial(color: .blue, isMetallic: false)]) cylinder.position = [0,-0.1,0] cylinder.generateCollisionShapes(recursive: false) cylinder.components[PhysicsBodyComponent.self] = .init(PhysicsBodyComponent(massProperties: .default, mode: .static)) cylinder.physicsBody = nil cylinder.scale = [500, 100, 100] anchor.addChild(cylinder) } The plane model in this issue is the BaseCircle. Any suggestions on how to solve this or potential fixes would be greatly appreciated

Hey there, I am working on an app that displays environmental data using PNG color channels to represent data ranges, which gets overlayed on a map. The sampled values aren't what I'm expecting though... for example an RGB value of 0x7f0000 (R = 0.5, G = 0, B = 0) would be seen as 0.21, 0, 0 in the shader. This basically makes it unusable if I'm trying to show scientific data... I'm half wondering if I am completely misunderstanding how sampling works in RealityKit / RealityComposerPro. Anybody have any idea why it works like this? Actual result (chart labels added in photoshop): Expected: Red > 0.1 Shader Graph

We're developing a VisionOS application, where we would like to do product recognition (like food items). We have enterprise entitlements and therefore also main camera access for VisionOS. We send this live camera frames to a trained CoreML model where we will receive 2D coordinates from the model detection prediction. Now, we would like to create a 3D anchor on the detected items so it can be visible for user. The 3D anchor is going to be the class name of the detected item. How do we transform this 2D coordinate from the model prediction to a 3D anchor?

if I set UIApplicationPreferredDefaultSceneSessionRole to UISceneSessionRoleImmersiveSpaceApplication then my Immersive Space for image is working fine but when I try with UIWindowSceneSessionRoleApplication this option and try to open Immersive space on particular sub screen then its not showing image in immersive space(Immersive space not open). Any one have idea what the issue. &lt;key&gt;UIApplicationSceneManifest&lt;/key&gt; &lt;dict&gt; &lt;key&gt;UIApplicationPreferredDefaultSceneSessionRole&lt;/key&gt; &lt;string&gt;UIWindowSceneSessionRoleApplication&lt;/string&gt; &lt;key&gt;UIApplicationSupportsMultipleScenes&lt;/key&gt; &lt;true/&gt; &lt;key&gt;UISceneConfigurations&lt;/key&gt; &lt;dict&gt; &lt;key&gt;UISceneSessionRoleImmersiveSpaceApplication&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;UISceneInitialImmersionStyle&lt;/key&gt; &lt;string&gt;UIImmersionStyleFull&lt;/string&gt; &lt;/dict&gt; &lt;/array&gt; &lt;/dict&gt; &lt;/dict&gt; My info.plist value as above

This issue has been since visionOS 1 unless that is how it is supposed to work. As you can see in the screen capture the shadows from the top box are shown on all 3 boxes below. This is a screen capture in composer pro but the same thing happens in the Vision Pro. Is there any way to stop this behavior and just have shadows on the first object below the object that is casting the shadows ?

When I try to open Immersive space I got error like below:- HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload How to solve it any idea?

I have a visionOS app using immersive space with RealityView. The app adds RealityKit entities to the app's Scene instance, and uses raycast to find CollisionCastHits. I want now to write a unit test to check if the app finds the right hits.
To do so, I have to access the Scene instance to add entities, and to check if they are hit by scene.raycast. But how can I access the scene instance? I can access it e.g. after creating the RealityView via its content parameter, or via @Environment(\.realityKitScene). But this seems not to be possible in a unit test. I tried the following test function: @MainActor @Test func test() async throws { var scene: RealityKit.Scene? await withCheckedContinuation { continuation in _ = RealityView(make: { content in print("make") let entity = Entity() content.add(entity) scene = entity.scene continuation.resume() }) } #expect(scene != nil) } But this logs ◇ Test test() started.
SWIFT TASK CONTINUATION MISUSE: test() leaked its continuation! The reason is apparently that the make closure of RealityView is only called when SwiftUI calls it within the body of a SwiftUI View. So, is it possible at all to access the app's scene i a unit test?

How can I guide users to set their preferred language in visionOS? At this point, the behavior seems to be different from that of iOS.

i have normal application flow and at one place i have to open immesive space for image seen 360 view but currently when ever i run application it start with immersive space my app normal flow is not start.What the isssue here?

Hi, I added DockingRegion to my scene from Reality Composer Pro, and I am able to load up the scene, but DockingRegion is getting ignored and the scene is getting rendered with no change in AVPlayerViewController window. As it can be seen in Reality Composer Pro screenshot below, I set the width of the player to 666, and moved it to the back by 300cm, but the actual result does not reflect the position I set on Reality Composer Pro. Is there anything else I should do other than loading up the Entity and adding to RealityView? Specifically, do I have to get the DockingRegion within the usda file and somehow enable it?

Reality Composer Pro question related to custom components My custom component defines some properties to edit in RCP. Simple ones work find, but SIMD3 and SIMD2 do not. I'd expect to see default values but instead I get this 0s. If I try to run this the scene doesn't load. Once I enter some values it does and build and run again it works fine. More generally, does Apple have documentation on creating properties for components? The only examples I've seen show simple strings and floats. There are no details about vectors, conditional options, grouping properties, etc. public struct EntitySpawnerComponent: Component, Codable { public enum SpawnShape: String, Codable { case domeUpper case domeLower case sphere case box case plane case circle } // These prooerties get their default values in RCP /// The number of clones to create public var Copies: Int = 12 /// The shape to spawn entities in public var SpawnShape: SpawnShape = .domeUpper /// Radius for spherical shapes (dome, sphere, circle) public var Radius: Float = 5.0 // These properties DO NOT get their default values in RCP. The all show 0 /// Dimensions for box spawning (width, height, depth) public var BoxDimensions: SIMD3<Float> = SIMD3(2.0, 2.0, 2.0) /// Dimensions for plane spawning (width, depth) public var PlaneDimensions: SIMD2<Float> = SIMD2(2.0, 2.0) /// Track if we've already spawned copies public var HasSpawned: Bool = false public init() { } }

Hi, When closing a WindowGroup, I want to show a prompt, and only dismiss the window when the user confirms. How to do it? WindowGroup(id: "A") { ContentView() }

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.
