Unity visionOS Development: A Comprehensive Guide
summary
Unity compiles C# into an Xcode project, uses AR Foundation for head/hand tracking and anchors, and routes Unity’s simulation through a PolySpatial bridge so RealityKit does final rendering (Shader Graph → MaterialX → RealityKit). Built projects include a HoloKit-powered co‑space multiplayer game “Magic” using MultipeerConnectivity that works; particles sometimes bake to mesh. Limitations: one real-time display volume camera only (no multi‑volume), no runtime MR↔VR switch, full-screen post‑processing unsupported, and Play to Device mirrors only ShareSpace, not VR.
