HoverEffectComponent on macOS 15 and iOS 18 works fine using RealityView, but seems to be ignored when ARView (even with a SwiftUI UIViewRepresentable) is used. Feedback ID: FB15080805

Hi everyone, I am wondering under which settings the camera(s) were set by the time they were calibrated. For instance, one aspect that is easy to find is the reference resolution of the images taken when calibrating the intrinsics, this is by retrieving intrinsicMatrixReferenceDimensions. Making sure that the principal point is referenced to the by the time resolution used when the calibration was ongoing. However, recently I saw that there are focusing modes that potentially displace the lens' physical position. Settings like: AutoFocusRangeRestriction: none, near, far setFocusModeLocked: Locks the lens position at the specified value, and sets the focus mode to a locked state. My concern lies the impact this focusing lens displacements can have on the intrinsic matrix parameters, like these parameters no longer describe the camera since the lens position has changed. In simple words, what is the focus 'mode'/'range' the cameras were set when calibrating them for intrnisics?

Im just trying to setup some kind of visual on my iPad for testing and play purposes... I tried adding iPad to both APPLE Visual APPS. I get this error for both Building for 'iphoneos', but '12.0' must be >= '18.0'

Hello, I checked following documentations. Vision | Apple Developer Documentation Discover Swift enhancements in the Vision framework - WWDC24 - Videos - Apple Developer I saw Vision Framework is available on visionOS. So I want to know that if it's possible using Vision Framework on visionOS for tracking human and animal body poses. Or are there some limits to use this on visionOS?

Here is the code snippets. struct RealityViewTestView: View { @State private var texts: [String] = [] var body: some View { RealityView { content, attachments in } update: { content, attachments in for text in texts { if let textEntity = attachments.entity(for: text) { textEntity.position.x = Float.random(in: -0.1...0.1) content.add(textEntity) } } } attachments: { ForEach(texts, id: \.self) { text in Attachment(id: text) { Text(text) .padding() .glassBackgroundEffect() } } } .toolbar { ToolbarItem { Button("Add") { texts.append(String(UUID().uuidString.prefix(6))) } } ToolbarItem { Button("Remove") { texts.remove(at: Int.random(in: 0..<texts.count)) } } } } } struct RealityViewTestView: View { @State private var texts: [String] = [] @State private var entities: [Entity] = [] var body: some View { RealityView { content, attachments in } update: { content, attachments in // for text in texts { // if let textEntity = attachments.entity(for: text) { // textEntity.position.x = Float.random(in: -0.1...0.1) // content.add(textEntity) // } // } for entity in entities { content.add(entity) } } attachments: { ForEach(texts, id: \.self) { text in Attachment(id: text) { Text(text) .padding() .glassBackgroundEffect() } } } .toolbar { ToolbarItem { Button("Add") { //texts.append(String(UUID().uuidString.prefix(6))) let m = ModelEntity(mesh: .generateSphere(radius: 0.1), materials: [SimpleMaterial(color: .white, isMetallic: false)]) m.position.x = Float.random(in: -0.2...0.2) entities.append(m) } } ToolbarItem { Button("Remove") { //texts.remove(at: Int.random(in: 0..<texts.count)) entities.removeLast() } } } } } About the first code snippet, when I remove an element from the texts, why content can automatically remove the corresponding entity? And about the second code snippet, content do not automatically remove the corresponding entity. I am very curious.

When using RoomPlan to collect data and processing it with StructureBuilder, the app crashes. Crash thread: RoomScanCore.offlineFloorPlanGeneration How should I deal with this issue? I’ve already implemented crash capture, but no crash was logged—the app just crashes directly. RoomScanCore.offlineFloorPlanGeneration

Hi, I would like to train Gaussian splats from my object captures. So I need a pointcloud and camera positions together with the original photos taken to train GS In an app like postShot. I could do this with Reality Capture, which supports exporting pointclouds and camera position but it does not do well with turntable photogrammetry. While the Apple object capture API does produce really solid results with turntable images. so my question is, can I export camera data from my object captures to use in another application? Or is there may be a plan to at this feature in the future? It would be really helpful in creating ultra realistic, 3-D objects in Gaussian splat format. Thanks for any isuggestions…

This might be a very silly question, anyway I tried many ways and didn't find a solution: My Mac mini M4 is basic version which only has 16GB memory, it is very shy for developing Vision Pro application and testing with the simulator (CleanMacX always warning me low memory), I want to debug and test the application directly on Vision Pro (+ my app need both two hands gestures which simulator might not support) in stead of simulator, is there any proper instructions on how I test/debug/run the App on VP device directly instead of on simulator in favor of speed?

In the particle effect of RealityKit, there is a Type: ParticleEmitterComponent.Presets He can invoke certain particle effects in certain systems, but I am interested in learning how to modify these particle entities (such as adjusting the color, the number of particles, the generation range…)?

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.

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!

Is there a way to provide CLHeading in visionOS so I can more accurately understand the direction in which a user is facing?

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)

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?

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?

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.

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() }
