An incomprehensible error occurs whenever I try to access Main Camera features. I have already acquired the Main Camera entitlement and granted the required permissions, yet the error persists. To make matters worse, even Apple’s provided sample code triggers the exact same issue. The error message is far too uninformative to diagnose the root cause, and I urgently need a resolution as this is completely blocking progress.

Hi all, We're currently evaluating Private Cloud Compute (PCC) for a technical accuracy assessment. No production release or monetization is planned at this stage — our only goal is to test/evaluate the model. Per the official documentation, PCC access requires: Enrollment in the App Store Small Business Program Fewer than 2 million first-time downloads The Private Cloud Compute entitlement assigned to the account To complete Small Business Program enrollment, our Paid Applications Agreement is currently stuck at "User Information Pending", and we're being asked to submit a bank account and U.S. tax forms (Certificate of Foreign Status of Beneficial Owner / Substitute Form W-8BEN-E) before the agreement can go Active. Honestly, we're having a hard time accepting that submitting banking and revenue-related tax documentation is required when we have no intention of selling a paid app at all. The Small Business Program itself is meant to be a reduced-commission program for developers earning revenue through paid apps/IAP — using it as a gate for free AI model evaluation feels like a mismatch. On top of that, we're a Japan-based company, which raises the bar further. The required tax forms (W-8BEN-E etc.) are aimed at non-US entities and require pulling in our legal/finance teams just to prepare — a fair amount of overhead for what is, on our end, purely a technical evaluation. Before we go through the internal process of preparing this documentation, I wanted to confirm: Is there any path to obtain the PCC entitlement / Small Business Program status for evaluation purposes only, without completing the full Paid Applications Agreement (banking + tax forms)? Is submitting real banking and tax information a hard technical requirement of the Small Business Program itself (i.e., the Paid Apps Agreement cannot go Active without it), or can an account remain PCC-eligible while the agreement is "pending"? Is there an official Apple document (beyond the general Small Business Program / PCC pages) that explicitly confirms banking/tax submission is mandatory before PCC entitlement can be granted? We need something citable for internal approval. For non-US companies (e.g. Japan-based), has anyone gone through this purely for evaluation purposes? Is there any simplified path for foreign entities, or is the full W-8BEN-E process unavoidable? Any pointers to official documentation, or confirmation from anyone who has been through this, would be greatly appreciated — we need a clear, citable answer to justify preparing this documentation internally. Thanks in advance.

Hello, I am experiencing an issue where lighting is disabled within a Portal Component specifically when using Progressive or Full Immersion styles in visionOS 26.2. [Steps to Reproduce] Create a scene in Reality Composer Pro with custom lighting (Directional Light, IBL, etc.) and load it as an Entity. Add a PortalComponent to this Entity. Observe the Entity in an ImmersiveSpace under different Immersion Styles. [Observed Behavior] Mixed Immersion: Lighting works as expected.Progressive / Full Immersion: Lighting is disabled, causing the content to render incorrectly. [Additional Context] Without PortalComponent: The same Reality Composer Pro scene renders lighting correctly across all Immersion Styles (Mixed, Progressive, and Full).Regression: In applications built with Xcode 16.4 / visionOS 2.5, lighting inside the Portal functioned correctly. This issue appears to have emerged with Xcode 26.2 and visionOS 26.2. [Questions] Is the disabling of lighting inside Portals during Full/Progressive Immersion an intended architectural change or optimization in visionOS 26.2? Are there any workarounds, such as specific PortalComponent configurations or new API flags, to re-enable lighting in these immersion modes? Thank you.

Hello, When I recently distributed my app, I received the following warning message: "Starting April 2026, all visionOS apps must be built with the visionOS 26 SDK or later, included in Xcode 26 or later, in order to be uploaded to App Store Connect or submitted for distribution." However, the Apple Developer News page dated February 3 (https://developer.apple.com/news/?id=ueeok6yw) states that apps submitted to the App Store must meet the version 26 requirement starting April 28, 2026. I need to clarify whether the mandatory enforcement begins on April 1, 2026, or April 28, 2026. As the major specification changes in version 26 are significantly impacting our current app development, the exact deadline is critical for us to determine our updated development schedule. https://developer.apple.com/forums/thread/814892 Thank you.

Hello, I am currently considering developing a Full Space app that enables a shared visionOS experience with nearby users. Intended Features A Mixed Full Space app in which dozens of 3D models are placed in the space. These 3D models may play embedded animations when tapped, be programmatically moved or rotated, or be controlled via Reality Composer Pro timelines. The app also includes audio, spatial audio, videos with audio, and videos without audio, which are rendered as VideoTextures on planes and played back in the space. Some media elements play automatically, while others are triggered by user interaction. However, it is unclear whether AVPlaybackCoordinator supports shared playback across multiple types of media, such as: audio only spatial audio video without audio video with audio I am also unsure whether there are alternative or recommended approaches for synchronizing playback in this scenario. Questions Is it technically possible to implement the experience described above using visionOS? Are there any important implementation considerations or limitations that should be taken into account? For example, when two participants experience the app simultaneously, how is the content positioned for each participant? Is the spatial placement of content shared across participants, or is it positioned relative to each participant’s viewpoint? For nearby participants, is it necessary to register a spatial Persona? My understanding is that spatial Personas are not visible for nearby users during the experience; is this correct? When experiencing SharePlay with nearby users, is it possible to share the experience without registering the other participant’s contact information? I have watched the following session, but I was unable to fully understand the feasibility of the above use case or the concrete implementation details: https://developer.apple.com/videos/play/wwdc2025/318/ Thank you.

Hello, Let me ask you a question about Apple Immersive Video. https://www.apple.com/newsroom/2024/07/new-apple-immersive-video-series-and-films-premiere-on-vision-pro/ I am currently considering implementing a feature to play Apple Immersive Video as a background scene in the app I developed, using 3DCG-created content converted into Apple Immersive Video format. First, I would like to know if it is possible to integrate Apple Immersive Video into an app. Could you provide information about the required software and the integration process for incorporating Apple Immersive Video into an app? It would be great if you could also share any helpful website resources. I am considering creating Apple Immersive Video content and would like to know about the necessary equipment and software for producing both live-action footage and 3DCG animation videos. As I mentioned earlier, I’m planning to play Apple Immersive Video as a background in the app. In doing so, I would also like to place some 3D models as RealityKit entities and spatial audio elements. I’m also planning to develop the visionOS app as a Full Space Mixed experience. Is it possible to have an immersive viewing experience with Apple Immersive Video in Full Space Mixed mode? Does Apple Immersive Video support Full Space Mixed? I’ve asked several questions, and that’s all for now. Thank you in advance!

I have two questions regarding releasing an app that uses an in-app browser (WKWebView) on the App Store worldwide. Question 1: Encryption usage Our app uses WKWebView and relies on standard encryption. Should this be declared as using encryption during the App Store submission? Question 2: If the answer to Question 1 is YES If it must be declared as using encryption, do we need to prepare and upload additional documentation when submitting the app in France? Also, would this require us to redo the entire build and upload process, even for an app version that has already been uploaded? Goal / request: We want to release an app using WKWebView worldwide, including France. We would like to understand all the necessary steps and requirements for completing the App Store release without unexpected rework. Best regards, P.S.: A similar question was posted a few years ago, but it seems there was no response. https://developer.apple.com/forums/thread/725047 Sadao

I’m currently developing a visionOS app that includes an RCP scene with a large USDZ file (around 2GB). Each time I make adjustments to the CG model in Blender, I export it as USDZ again, place it in the RCP scene, and then build the app using Xcode. However, because the USDZ file is quite large, the build process takes a long time, significantly slowing down my development speed. For example, I’d like to know if there are any effective ways to: Improve overall build performance Reduce the time between updating the USDZ file and completing the build Any advice or best practices for optimizing this workflow would be greatly appreciated. Best regards, Sadao

I have a question about Apple’s preinstalled visionOS app “Encounter Dinosaurs.” In this app, the dinosaurs are displayed over the real-world background, but the PhysicallyBasedMaterial (PBM) in RealityKit doesn’t appear to respond to the actual brightness of the environment. Even when I change the lighting in the room, the dinosaurs’ brightness and shading remain almost the same. If this behavior is intentional — for example, if the app disables real-world lighting influence or uses a fixed lighting setup — could someone explain how and why it’s implemented that way?

Hello everyone, I am currently developing an experience for visionOS using RealityKit and I would like to achieve volumetric light effects, such as visible light rays or shafts through fog or dust. I found this GitHub project: https://github.com/robcupisz/LightShafts, which demonstrates the kind of visual style I am aiming for. I would like to know if there is a way to create similar effects using RealityKit on visionOS. So far, I have experimented with DirectionalLight, SpotLight, ImageBasedLight, and custom materials (e.g., additive blending on translucent meshes), but none of these approaches can replicate the volumetric light shaft look shown in the repository above. Questions: Is there a recommended technique or workaround in RealityKit to simulate light shafts or volumetric lighting? Is creating a custom mesh (e.g., cone or volume geometry with gradient alpha and additive blending) the only feasible method? Are there any examples, best practices, or sample projects from Apple or other developers that showcase a similar visual style? Any advice or hints would be greatly appreciated. Thank you in advance!

Hello, Thank you for your time. I have a question regarding visionOS app development. When placing a SwiftUI TextField inside RealityView.attachments, we found that focusing on the field does not bring up the virtual keyboard in front of the user. Instead, the keyboard appears around the user’s lower abdomen area. However, when placing the same TextField in a regular SwiftUI layer outside of RealityView, the keyboard appears in the correct position as expected. This suggests that the issue is specific to RealityView.attachments. We are currently exploring ways to have the virtual keyboard appear directly in front of the user when using TextField inside RealityViewAttachments. If there is any method to explicitly control the keyboard position or any known workarounds—including alternative UI approaches—we would greatly appreciate your guidance. Best regards, Sadao Tokuyama

Hello, I'm working with the new PortalComponent introduced in visionOS 2.0, and I've encountered some issues when transitioning entities between virtual and real-world spaces using crossingMode. Specifically: Lighting inconsistency: When CG content (ModelEntities with PhysicallyBasedMaterial) crosses the portal from virtual space into the real environment, the way light reflects on the objects changes noticeably. This causes a jarring visual effect, as the same material appears differently depending on the space it's in. Unnatural transition visuals: During the transition, the CG models often appear to "emerge from the wall," especially when crossing from virtual to real. This ruins the immersive illusion and feels visually unnatural. IBL adjustment attempts: I’ve tried adding an ImageBasedLightComponent to the world entity, and while it slightly improves the lighting consistency, the issue still remains to a noticeable degree. My goal is to create a seamless visual experience when CG entities cross between spaces, without sudden lighting shifts or immersion-breaking geometry reveals. Has anyone else experienced similar issues? Is there a recommended setup or workaround to better control lighting and visual fidelity when using crossingMode with portals in visionOS 2.0? Any guidance would be greatly appreciated. Thank you!

Hi, I have a question. In visionOS, when a user looks at a button and performs a pinch gesture with their index finger and thumb, the button responds. By default, this works with both the left and right hands. However, I want to disable the pinch gesture when performed with the left hand while keeping it functional with the right hand. I understand that the system settings allow users to configure input for both hands, the left hand only, or the right hand only. However, I would like to control this behavior within the app itself. Is this possible? Best regards.

Hi, I would like to learn how to create custom materials using Shader Graph in Reality Composer Pro. I would like to know more about Shader Graph in general, including node descriptions and how the material's display changes when nodes are connected. However, I cannot find a manual for Shader Graph in Reality Composer Pro. This leaves me totally clueless on how to create custom materials. Thanks.
