Apple RealityKit is a high-level framework that helps a developer to load and render AR/VR models with PBR shaders, animations and physics simulations for iOS, visionOS and macOS apps.

RealityKit is an Apple framework for building, animating and rendering 3D scenes. It was introduced at WWDC 2019 for iOS and macOS, and at WWDC 2023 for visionOS. RealityKit allows us implement a high-performance life-like 3D simulation, or fulfil a physically based rendering for its companion – and frameworks – to seamlessly integrate virtual objects into the real world.

Using this framework you can asynchronously load assets in .usdz and .reality formats, or in .rcproject format that stores compositions of app. Starting from Xcode 15, there will be the Reality Composer Pro app.
