'''RealityKit''' is a | '''RealityKit''' is a 3D [[framework]] developed by [[Apple Inc.]] for creating [[augmented reality]] (AR) and [[spatial computing]] experiences across Apple platforms. The RealityKit framework was built specifically for augmented reality with camera effects, animations, physics, and more. RealityKit was first introduced at the [[Worldwide Developers Conference]] (WWDC) 2019 on June 3 alongside [[iOS 13]], [[iPadOS 13]], and [[macOS 10.15]] (Catalina), with public release on September 19, 2019<ref name="wwdc2019">Apple reveals ARKit 3 with RealityKit and Reality Composer by Jeremy Horwitz, VentureBeat. 2019-06-03.</ref>. The framework provides developers with native [[Swift (programming language)|Swift]] [[API]]s for realistic [[rendering]], [[animation]], [[physics simulation]], and [[spatial audio]], making AR development more accessible and efficient. | ||

RealityKit and [[ARKit]] are designed to work together but serve different purposes. ARKit is responsible for understanding the real world by processing data from the device's camera and motion sensors, performing tasks such as [[plane detection]], [[image tracking]], and [[world tracking]]<ref name="arkitrelation">RealityKit Documentation - Apple Developer. https://developer.apple.com/documentation/realitykit</ref>. RealityKit takes the information from ARKit and uses it to place and interact with virtual content in the real world. In essence, ARKit "sees" the world, and RealityKit "draws" the virtual objects in it. | RealityKit and [[ARKit]] are designed to work together but serve different technical purposes.
