A focused guide for building 3D and AR experiences with Apple's RealityKit framework, covering everything from basic Entity-Component-System patterns to visionOS spatial computing. You'd reach for this when working with RealityView in SwiftUI, setting up AR anchors for world or body tracking, or handling physics and collision systems. The skill targets iOS 13+ with full visionOS support, making it relevant whether you're building iPhone AR apps or immersive spatial experiences. Worth noting it comes from the axiom collection, which has decent traction at 948 GitHub stars, and it passes most security audits. If you're migrating from SceneKit or starting fresh with Apple's 3D stack, this gives you the practical guidance without wading through Apple's reference docs.
