What problem does it solve?

RealityKit + ARKit empower developers to build immersive AR experiences on iOS with a robust rendering pipeline, world tracking, and intuitive interaction patterns, reducing boilerplate and setup overhead.

Core Features & Use Cases

  • RealityView-based AR rendering and camera integration
  • Entity loading, placement, and raycasting in real-world spaces
  • Gestures and interaction patterns for engaging AR scenes
  • Scene understanding and per-frame updates for dynamic content
  • Common use cases include AR product demos, education, and interactive visuals

Quick Start

Create a simple AR scene by placing a virtual cube in front of the camera using RealityView and toggle basic gestures.

Frequently Asked Questions about realitykit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I place virtual objects in real-world spaces using RealityKit raycasting?▼

RealityKit raycasting places virtual objects in real-world spaces by casting rays from ARView to detect surfaces, then anchoring loaded entities to those hit-test results for accurate placement.

What's the best way to render AR scenes in SwiftUI using RealityView?▼

Rendering AR scenes in SwiftUI with RealityView integrates world tracking and camera workflows directly into your views, managing entity loading and per-frame updates for dynamic AR content.

Can I use ARKit gestures for interactive object placement in RealityKit?▼

Yes, ARKit gestures work with RealityKit for interactive object placement, enabling intuitive manipulation and engaging interaction patterns for virtual entities anchored in your AR scene.

Do I need camera usage permissions and device capability checks for iOS AR development?▼

Yes, iOS AR development requires camera usage permissions and device capability checks to ensure the device supports ARKit world tracking before initializing RealityView for rendering.

Why does asynchronous entity loading fail in RealityKit ARView scenes?▼

Asynchronous entity loading in RealityKit ARView scenes fails when device capability checks are skipped or camera usage requirements are unmet, preventing proper world tracking initialization.
