RealityKit enables developers to craft AR experiences on iOS, simplifying rendering, scene management, and real-world interaction by combining SwiftUI-compatible interfaces with ARKit-powered world tracking.
Create a basic RealityKit AR scene with a single ModelEntity sphere placed in front of the camera using RealityView.

To load and place 3D models in iOS AR, use RealityView to render the scene and manage ModelEntity or USDZ assets. You can position these entities in the real world by raycasting against plane anchors to determine spatial placement coordinates.
Yes, RealityKit handles gesture interactions with 3D objects by combining ARKit world tracking with SwiftUI-compatible interfaces. You can attach gestures to ModelEntity objects, allowing users to tap, rotate, or move virtual items within the anchored AR scene.
The best way to check device capabilities for an ARKit session is to verify support before configuring RealityView. RealityKit requires specific hardware checks for world tracking and scene understanding, ensuring the iOS device can handle the AR rendering and environmental lighting.
RealityKit applies per-frame updates by continuously processing ARKit session data to refine scene understanding. This mechanism tracks plane anchors and environment lighting cues in real-time, ensuring virtual ModelEntity objects remain realistically lit and anchored to physical surfaces.
Yes, RealityKit supports loading and rendering USDZ assets for interactive product previews. By integrating USDZ models as ModelEntity objects within a RealityView, you can create realistic demonstrations with proper environment lighting and spatial placement via raycasting.
