ARKit Apple AR

ARKit is Apple's framework for augmented reality on iOS. It provides world tracking (knows device position/orientation), plane detection (walls, tables), light estimation, and face tracking. Developers use ARKit with RealityKit (rendering engine) to build AR experiences: placing 3D models, detecting objects, face filters. ARKit is tightly integrated with iOS hardware: LiDAR on iPad Pro and iPhone 12/13/14/15 enables faster plane detection. Vision Pro (Apple's MR headset) uses ARKit concepts, making ARKit a foundation skill for spatial computing.
