There a way to use contentCaptureProtected with Quick Look on VisionOS 26? Or exist a way to see a spatial photo with Quick Look without sharing options ?

.glassEffect(.regular, in: .rect(cornerRadius: 24)) error; 'glassEffect(_:in:isEnabled:)' is unavailable in visionOS This is not surprising since visionOS already has a native glass interface that formed a model for the other OS's, but this error will create additional overhead for developers creating multi-platform apps that include visionOS.

Since only the user can take a screenshot using the Apple Vision Pro's top buttons, the only workaround available to an immersive app that needs a screenshot to document the user's creative interior design choices is ask the user to take a screenshot wait until the user taps a button indicating the screenshot has been taken then the app asks the user to select the screenshot when the app opens the PhotoPicker when the user presses Done, the screenshot is handed off to the app. One wonders why there is no Apple Api for doing this in a simple privacy protective way such as: When called, the Apple api captures the screenshot in Apple secured memory The api displays the screenshot to the user with appropriate privacy warnings and asks if the user wants to a. share this screenshot with the app, or b. cancel, c. retake the screenshot If the user approves, the app receives the screenshot

I would like to know if there have been any updates that improved the image tracking speed. I submitted feedback a while ago, mentioning that the image tracking rate was only one frame per second on Vision Pro. Thank you very much. FB15688516 and FB16745373is feedback we previously submitted, but we have not received any response yet.

My ARViewContainer code is not working. I don't know how to debug the issue and I don't know or see where my results is going to. I need help to resolve this issue. please help debug. See code below:

Hi everyone, I'm creating an educational App that allows doing computational design in an immersive environment with the Vision Pro. The App is free and can be found here: https://apps.apple.com/us/app/arcade-topology/id6742103633 The problem I have is that the mesh of voxels I currently create use ModelEntity and I recently read that this is horrible for scalability. I already start to see issues when I try to use thousands of voxels. I also read somewhere that I should then take advantage of GPUs and use metal to that end. I was wondering if someone could point me to a tutorial or article that discusses this. In essence, I need to create a 3D voxel mesh, and those voxels have to update their opacity within an iterative loop. Thanks! —Alejandro

The initial startup of visionOS 26 after install is glacially slow.

I am trying to launch a fully immersive game from Unity on a SwiftUI view. The game is using Metal Rendering with Compositor Services. I added the unity Xcode project into the workspace, added the necessary bridge code. When I click on the button to call ufw?.showUnityWindow(), it does not start and I get the following in the console: AR session failed to start after 5 seconds. Is the app configured to use an immersive space?

Hello! I'm a developer of Ping Pong for Apple Vision Pro (Ping Pong Club). I'm experiencing an issues with collisions between ball and paddle. Sometimes the ball just unexpectedly flying away like it has been hit to hard. I believe this is happening because hand anchors are jittering (ping pong paddle has hand anchor component) and at the time of collision unnecessary micro motion produced. I've build a demo app to demonstrate that: https://drive.google.com/file/d/1gBh-DsXuVZdvDrrD7gJcbJ_hg7tvVKUV/view?usp=share_link Video: https://drive.google.com/file/d/1poPbsJdBz87edqrWIfBt1eSVzfm5CTek/view?usp=sharing Is there a way to add some threshold to prevent jittering?

I am allowing users to go through and capture different rooms, and add a custom label to that room. Is there a way to store data about this in the captured room so that it persists into the final merge? As it is now, My users mark all their merges with custom labels, but after merging there is no way to remember which room is which in the merging process so they have to go through and manually add the labels back. For larger floor plans this is not ideal.

In several visionOS apps, we readjust our scenes to the user's eye level (their heads). But, we have encountered issues whereby the WorldTrackingProvider returns bad/incorrect positions for the first x number of frames. See below code which you can copy paste in any Immersive Space. Relaunch the space and observe the numberOfBadWorldInfos value is inconsistent. a. what is the most reliable way to get the devices's position? b. is this indeed a bug? c. are we using worldInfo improperly? d. as a workaround, in our apps we set to 10 the number of frames to let pass before using worldInfo, should we set our threshold differently? import ARKit import Combine import OSLog import SwiftUI import RealityKit import RealityKitContent let SUBSYSTEM = Bundle.main.bundleIdentifier! struct ImmersiveView: View { let logger = Logger(subsystem: SUBSYSTEM, category: "ImmersiveView") let session = ARKitSession() let worldInfo = WorldTrackingProvider() @State var sceneUpdateSubscription: EventSubscription? = nil @State var deviceTransform: simd_float4x4? = nil @State var numberOfBadWorldInfos = 0 @State var isBadWorldInfoLoged = false var body: some View { RealityView { content in try? await session.run([worldInfo]) sceneUpdateSubscription = content.subscribe(to: SceneEvents.Update.self) { event in guard let pose = worldInfo.queryDeviceAnchor(atTimestamp: CACurrentMediaTime()) else { return } // `worldInfo` does not return correct values for the first few frames (exact number of frames is unknown) // - known SO: https://stackoverflow.com/questions/78396187/how-to-determine-the-first-reliable-position-of-the-apple-vision-pro-device deviceTransform = pose.originFromAnchorTransform if deviceTransform!.columns.3.y < 1.6 { numberOfBadWorldInfos += 1 logger.warning("\(#function) \(#line) deviceTransform.columns.3.y \(deviceTransform!.columns.3.y), numberOfBadWorldInfos \(numberOfBadWorldInfos)") } else { if !isBadWorldInfoLoged { logger.info("\(#function) \(#line) deviceTransform.columns.3.y \(deviceTransform!.columns.3.y), numberOfBadWorldInfos \(numberOfBadWorldInfos)") } isBadWorldInfoLoged = true // stop logging. } } } } }

Hi there I'm using Reality Composer Pro to anchor virtual content to a .referenceobject. However by moving the referenceobject quickly, it causes tracking to stop. (I know this is a limitation so im trying to make it a feature) IS there a way to play a USDZ animation at the last known location, after detecting that reference object is no longer being tracked? is it possible to set this up in Reality Composer pro? Nearly everything is set up in Reality Composer pro with my immersive.scene just anchoring virtual content to the Reference object 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 & WorldTrackProvider, 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 if this is actually the right way to do it. Apologies for my lack of knowledge.

We are building an AR experience for deployment on iphones. We are using Unity but it looks as if Reality Composer Pro has better features for spatial audio. I am not sure if Reality Composer Pro can only be used for Vision Pro or can it also be used for deployment on Iphone or ipad.

In my Reality Composer Pro workflow for Vision Pro development, I’m using xcrun realitytool image to pre-compress textures into .ktx format, typically using ASTC block compression. These textures are used for cubemaps and environment assets. I’ve noticed that regardless of the image content—whether it’s a highly detailed photo or a completely black image—once compressed with the same ASTC block size (e.g., ASTC_8x8), the resulting .ktx file size is nearly identical. There appears to be no content-aware logic that adapts the compression ratio to the actual texture complexity. In contrast, Unreal Engine behaves differently: even when all cubemap faces are imported at the same resolution as DDS textures, the engine performs content-aware compression during packaging: Low-complexity images are compressed more aggressively The final packaged file size varies based on content complexity Since Reality Composer Pro requires textures to be pre-compressed as .ktx, there’s no opportunity for runtime optimization or per-image compression adjustment. Just wondering: is there any recommended way to implement content-aware compression for .ktx textures in Reality Composer Pro? Or any best practices to optimize .ktx sizes based on image complexity? Thanks!

I'm developing an AR application for the iPad pro where the primary purpose is to overlay 3D design data on top of production parts. For alignment, we are using Vuforia (model targets) which work really well locally. The further the device is moved from the point of original alignment, we are seeing quite a bit of overlay error (drift?). My primary questions are: Are there any best practices to stabilize frame-to-frame tracking when using model targets? We are noticing drift as soon as the device starts moving (the drift appears to occur specifically in the direction the device is moving). After about 15 feet of movement, we are observing about 3-6" of overlay error These use cases can be over 100 feet long. In order to reset drift, we understand we'll need multiple alignment points (model targets) along the way. Is there a standard/best practice for this? Ex: have a new alignment point every x-feet? We are using plane anchors to set our alignment. Typically we attach it to the nearest plane; however, the anchor point can be very far away (the origin of the model, which often is not near where the virtual content is). Could this be the issue? The anchor is far from the plane that we attach it too. Would moving the anchor closer to the plane we attach it too improve stability? After a few steps, the plane we originally attach too will be out of FoV anyway. Thanks in advance!

In the DestinationVideo demo, the onAppear in UpNextView is triggered again when it is closed, but I only want it to be triggered once. How can I achieve this? Alternatively, I would like to capture the button click events in the player menu, as shown in the screenshot below.

Hi Apple Team and Developers, First of all, I’d like to express my appreciation for the incredible results achieved using PhotogrammetrySession. I’ve been developing a portrait scanning app using Object Capture, and in many tests—especially with human models—I’ve found the reconstructed body surfaces are remarkably smooth and clean, often outperforming tools like Metashape and RealityCapture in terms of aesthetic results. However, I’ve encountered some challenges when working with complex areas like long hair overlapping the face. For instance, with female models where strands of hair partially occlude the face, the resulting mesh tends to merge the hair and facial geometry. This leads to distorted or “melted” facial features, likely due to ambiguity in the geometry estimation phase. Feature Suggestion: Would it be possible to allow developers to supply two versions of the input images: • One version (original) for texture generation • A pre-processed version (e.g., contrast-enhanced or CLAHE filtered) to guide mesh reconstruction only This would give us the flexibility to enhance edge features or shadow detail without affecting the final texture appearance. In other photogrammetry pipelines, applying image enhancement selectively before dense reconstruction improves geometry quality in low-contrast areas. Question: Is there any plan to support this kind of two-path workflow in future versions of PhotogrammetrySession? Or perhaps expose more intermediate stages or tunable parameters to developers? Also, any hints on what we can expect from WWDC 2025 regarding improvements to Object Capture or related vision/3D technologies? Thanks again for this powerful API. Looking forward to hearing insights from the team and other developers. Warm regards, KitCheng

I’m working on a Vision Pro app using Metal and need to implement multi-pass rendering. Specifically, I want to render intermediate results to a texture, then use that texture in a second pass for post-processing before presenting the final output. What’s the best approach in visionOS? Should I use multiple render passes in a single command buffer or separate command buffers? Any insights on efficiently handling this in RealityKit or Metal? Thanks!

Anyone could share ideas or nodes setup to implement a gaussian blur on shader graph material, with a blur size parameter? Thanks!

I'm trying to add a feature to my app to allow a user to import items from other apps, like Safari, via the share sheet. I've done this many times on iOS/iPadOS easily with a Share Extension. From what I can tell, Xcode tells me share extensions are not available on visionOS - though my experience on device tells me differently (It seems Reminders, Notes & more implement them somehow.) I was finally able to get it working on device only...but I can now no longer test in the simulator, and have not found a way to distribute this app. When attempting to run on the simulator, I get this issue: Please try again later. Appex bundle at /Users/jason/Library/Developer/CoreSimulator/Devices/09A70160-4F4F-4F5E-B679-F6F7D876D7EF/data/Library/Caches/com.apple.mobile.installd.staging/temp.6OAEZp/extracted/LaunchBar.app/PlugIns/LaunchBarShareExtension.appex with id co.swiftfox.LaunchBar.ShareExtension specifies a value (com.apple.share-services) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. When trying to archive an upload to test flight, I get this similar error: Invalid Info.plist value. The value for the key 'DTPlatformName' in bundle LaunchBar.app/PlugIns/LaunchBarShareExtension.appex is invalid. (ID: 207610c7-b7e1-48be-959b-22a43cd32d16) The app is for visionOS only - which I'm thinking might be the problem? The share extension is "Designed For iPhone" and requires me to include iPhone as a run destination. In the worst case I can build an iPhone UI for the app but I'd rather not, as it is very specific to visionOS. Has anyone successfully launched a share extension on a visionOS only app? I have an iPad app with a share extension that shows up fine on visionOS, but the issue seems to be specifically with visionOS only apps.
