realitykit

What problem does it solve?

RealityKit simplifies the complex, platform-specific work of building augmented reality scenes by providing concrete patterns, examples, and checklists for rendering, entity management, placement, and interaction so developers avoid common performance and permission pitfalls.

Core Features & Use Cases

• RealityView & Camera Integration: Guidance for setting up RealityView, handling camera permission, and verifying ARWorldTracking capability before presenting AR content.
• Entity Creation & Loading: Patterns for programmatic mesh generation, asynchronous USDZ/model loading, adding components (physics, collision, input), and managing ECS-based behaviors.
• Placement, Raycasting & Interaction: Raycast-based placement, anchoring strategies for planes or world transforms, gesture-driven interactions (drag, tap), per-frame updates, and performance recommendations for production AR apps.

Quick Start

Add a RealityView to your SwiftUI view, asynchronously load a ModelEntity named robot, anchor it to the first detected horizontal plane, and enable collision and input components so it can be placed and dragged.
