A solid reference for building AR apps on iOS with RealityKit and ARKit. Covers the full workflow from setting up RealityView in SwiftUI to loading USDZ models, anchoring content to detected planes, and handling gestures on 3D entities. The raycasting section for tap-to-place interactions is a bit sparse, but the component system examples (physics, collision, input targeting) are clear and practical. Targets Swift 6.3 and iOS 26+, which is forward-looking but means you'll need to adjust APIs if you're shipping to current devices. Good for getting AR prototypes running quickly without digging through scattered Apple docs.
