RealityKit is a high-performance 3D framework developed by Apple Inc. for creating augmented reality (AR) and spatial computing experiences across Apple platforms. The RealityKit framework was built from the ground up specifically for augmented reality with photo-realistic rendering, 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. The framework provides developers with native Swift APIs for realistic rendering, animation, physics simulation, and spatial audio, making AR development more accessible and efficient.

Overview

RealityKit serves as Apple's primary 3D rendering and simulation engine for AR applications, designed to work seamlessly with ARKit to create immersive experiences. RealityKit provides high-performance 3D simulation and rendering capabilities you can use to create visionOS apps or to create augmented reality (AR) apps for iOS, macOS, and tvOS. The framework emphasizes ease of use while providing powerful capabilities for professional-grade AR experiences.

RealityKit is an AR first framework, which means that it's been completely designed from the ground up with an emphasis on AR application development. It leverages the power of Metal for optimized performance on Apple devices and integrates deeply with other Apple frameworks to provide a comprehensive AR development platform. All public APIs are written in Swift and adopt value semantics where possible, leveraging features like generics and property wrappers.

Relationship with ARKit

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. 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.

Architecture

Entity Component System

RealityKit uses an Entity Component System (ECS) architecture for organizing and managing 3D content. ECS, short for entity component system, is a way of structuring data and behavior that favors composition over inheritance, commonly used in games and simulations.

Core ECS Elements

Element	Description	Purpose
Entity	An entity is a container object that represents nodes in a scene graph	Represents objects in the scene (e.g., virtual chair, character)
Component	Each component enables some specific behavior for an entity	Defines properties and behaviors (position, appearance, physics)
System	Systems are a really effective way to implement a variety of effects and behaviors	Processes entities with specific components each frame

Simulation Loop

The simulation loop in RealityKit runs rendering, physics, and audio in synchrony at the native refresh rate of the host device. Developers place content relative to real-world or image anchors supplied by ARKit.

Key Components

RealityKit provides numerous built-in components for common AR functionality:

• ModelComponent: Provides mesh and materials for rendering
• Transform: Positions entities in 3D space
• CollisionComponent: Enables physics interactions
• AnchoringComponent: Anchors content to real-world features
• AudioComponent: Adds spatial audio
• AnimationComponent: Enables animations
• HoverEffectComponent: Provides visual feedback on gaze (visionOS)

Features

Rendering

RealityKit seamlessly blends virtual content with the real world using realistic, physically based rendering (PBR) materials, environment reflections, grounding shadows, camera noise, motion blur, and more to make virtual content nearly indistinguishable from reality. The rendering system includes:

• Physically Based Rendering (PBR) with HDR lighting
• Real-time shadows and reflections with global illumination
• Post-processing effects
• Custom materials and shaders using Metal Shading Language
• Video textures via VideoMaterial
• HDR support
• Image-based lighting for realistic reflections

Physics Simulation

With a powerful physics engine, RealityKit lets you throw anything at it — pun intended! You can adjust real-world physics properties like mass, drag and restitution, allowing you to fine-tune collisions. Features include:

• Rigid body dynamics
• Collision detection and shapes
• Real-world occlusion
• Scene understanding integration
• Joints and force fields
• Raycasting support

Animation

RealityKit supports multiple animation types:

• Transform-based animations
• Skeletal animations for character rigging
• Blend shapes for facial expressions
• Custom animation timelines and blend-tree mixing
• Procedural animations through custom systems
• Physics-based animations

Spatial Audio

Spatial audio understanding and automatic listener configuration let you attach sound effects to 3D objects. Every Entity defaults to a spatial audio emitter. You can then track those sounds, making them sound realistic based on their position in the real world. Features include:

• 3D positional audio
• Reverb zones
• Real-time procedural audio streaming
• Environmental audio effects

Networking

RealityKit simplifies building shared AR experiences by taking on the hard work of networking. The built-in MultipeerConnectivityService synchronises entity hierarchies across nearby devices using Multipeer Connectivity. Features include:

• Automatic synchronization of entities
• Consistent state maintenance
• Network traffic optimization
• Packet loss handling
• Ownership transfer mechanisms

Code Examples

Basic Scene Setup

A simple example of creating a RealityKit scene in Swift:

import RealityKit
import ARKit

// Create AR view
let arView = ARView(frame: .zero)

// Configure session
let config = ARWorldTrackingConfiguration()
config.planeDetection = [.horizontal, .vertical]
arView.session.run(config)

// Create anchor
let anchor = AnchorEntity(plane: .horizontal)

// Create entity with model
let box = ModelEntity(mesh: .generateBox(size: 0.1))
box.model?.materials = [SimpleMaterial(color: .blue, isMetallic: true)]

// Add to scene
anchor.addChild(box)
arView.scene.anchors.append(anchor)

Entity Component Example

Example of creating a custom component and system:

import RealityKit

// Define custom component
struct RotationComponent: Component {
    var speed: Float = 1.0
    var axis: SIMD3<Float> = [0, 1, 0]
}

// Register component
RotationComponent.registerComponent()

// Create custom system
class RotationSystem: System {
    required init(scene: Scene) { }
    
    func update(context: SceneUpdateContext) {
        for entity in context.entities(matching: EntityQuery(where: .has(RotationComponent.self))) {
            guard let rotation = entity.components[RotationComponent.self] else { continue }
            
            let angle = rotation.speed * context.deltaTime
            entity.transform.rotation *= simd_quatf(angle: angle, axis: rotation.axis)
        }
    }
}

// Register system
RotationSystem.registerSystem()

Spatial Audio Example

Adding spatial audio to an entity:

// Load audio resource
let audioResource = try await AudioFileResource.load(named: "sound.mp3")

// Create audio playback controller
let audioController = entity.prepareAudio(audioResource)

// Configure spatial audio
audioController.gain = -10 // decibels
audioController.isLooping = true
audioController.play()

// Add reverb effect
let audioEntity = Entity()
audioEntity.components[AudioComponent.self] = AudioComponent()
audioEntity.transform.translation = [0, 0, -2]
