Reality Composer Pro
To implement the Scene navigator, we will need to handle .usd manipulation, and the best approach I have found is to use Apple's SwiftUsd project. Although it is a bit behind the standard and has some quirks with C++ interops, it remains powerful and convenient, and by including

Viewport is deep (modes, debug views, presets/history). We are going to implement just a working viewer + camera for this pass; chasing full parity will balloon scope. The main viewport is built with RealityKit, and we'll add a layer for gestures, a grid, and a simple Arcball implementation

Part of what makes Reality Composer Pro a composer is asset management. Importing, soft validation, organizing, and iterating on the project structure are essential features to have in creative pipelines. The project browser in RCP is similar to Finder's grid view and, because of that, filled with UX
Dual-mode Inspector: scene layer shows global stage metadata (upAxis, metersPerUnit), while prim inspection displays transform, materials, and references. UI presents cm/degrees; USD persists meters/quaternions with rotationEulerHint for round-trip editing.

An exploration of the .realitycomposerpro document type. This post breaks down its structure as an SPM-backed package, the nested bundle system for assets, and how this layout could enable Xcode and `realitytool` processing.
Reality Composer Pro prioritizes the transition of elements over direct emphasis on creation and debugging tasks. It's a portal where you transport raw, wild formats to more manageable, controlled, static-defined files that can be represented on RealityKit.

Xcode runs a verified two-pass process to compile .reality files: first generating USD schemas from your Swift components, then compiling them into optimized bundles.
...and there are strong reasons against it. The conversation could be philosophical, but it highlights the conflicting opinions on whether commercial interests should take precedence over human well-being. Also, the few potential exceptions could be handled in controlled environments using entitlements or research. What Does Your Gaze Reveal About You?

Just updated the data source to include WWDC25 contents and recompiled for Tahoe because it is nicer... Download Transwwdcripts v1.2Download Resourwwdces v1.1TranswwdcriptsIn the spirit of ASCIIwwdc, understanding that transcripts have significant benefits for accessibility and research, creates a situation in which making text versions of talks available becomes
TL;DR * Spatial computing is in a transitional phase: the technology is robust, but the market and use cases are still catching up. * Apple’s approach is methodical, not flashy: rather than chasing hype, Apple is building the infrastructure—standards, APIs, specifications, developer tools—that will power the next wave
TL;DR, If you want virtual environment light gradually replacing your real-world shaded objects, use Virtual Environment Probe. Achieving visual realism for virtual elements involves many parts, but lighting stands out as particularly challenging, especially in real-time rendering for platforms like visionOS and RealityKit. Material surface behavior in response to
TL;DR, If you are interested in building a spatial game (or just about any immersive experience), you'll probably want to implement an architecture like TabletopKit. Create multiplayer spatial games on a virtual table surface and use FaceTime to invite players. TabletopKit first impressions We are creating a
TL;DR: SubD can currently only be activated on Reality Composer Pro and for geometry using physically based (not custom) materials. While working with 3D, especially for real-time rendering engines like RealityKit (the current engine powering visionOS), balancing geometry, material types, sizes, and render passes is critical for creating an
Towards Automated Accessibility Report Generation for Mobile AppsMany apps have basic accessibility issues, like missing labels or low contrast. Automated tools can help app developers catch basic issues…Apple Machine Learning Research One of the most commonly used tools for generating audits on Apple platforms is the Accessibility Inspector, specially
Conformance to accessibility standards reports or statements differ in format depending on region, but when referring to Information and communications technology products (ICT), they usually follow closely the Web Content Accessibility Guidelines (WCAG).
