SceneViewSwift

3D and AR scenes in SwiftUI, powered by RealityKit. The Apple companion to SceneView for Android.

Installation

Add SceneViewSwift via Swift Package Manager:

1. In Xcode, go to File > Add Package Dependencies...
2. Enter the repository URL:

   https://github.com/sceneview/sceneview-swift
   

3. Select the version rule and add the package to your target.

Or add it to your Package.swift:

dependencies: [
    .package(url: "https://github.com/sceneview/sceneview-swift", from: "3.6.0")
]

Quick Start

3D Model Viewer

import SwiftUI
import SceneViewSwift

struct ModelViewer: View {
    @State private var model: ModelNode?

    var body: some View {
        SceneView { content in
            if let model {
                content.addChild(model.entity)
            }
        }
        .environment(.studio)
        .cameraControls(.orbit)
        .autoRotate()
        .task {
            model = try? await ModelNode.load("robot.usdz")
        }
    }
}

AR Tap-to-Place

import SwiftUI
import SceneViewSwift

struct ARPlacement: View {
    @State private var model: ModelNode?
    @State private var placedEntities: [Entity] = []

    var body: some View {
        ARSceneView(
            planeDetection: .horizontal,
            onTapOnPlane: { position in
                if let model {
                    let clone = model.entity.clone(recursive: true)
                    clone.position = position
                    // Add to AR scene
                }
            }
        )
        .task {
            model = try? await ModelNode.load("chair.usdz")
        }
    }
}

Procedural Shapes with PBR

SceneView { root in
    let metal = GeometryNode.sphere(
        radius: 0.3,
        material: .pbr(color: .gray, metallic: 1.0, roughness: 0.1)
    )
    .position(.init(x: 0, y: 0.3, z: 0))
    .withGroundingShadow()
    root.addChild(metal.entity)
}
.environment(.sunset)

Lights

let sun = LightNode.directional(color: .warm, intensity: 1000, castsShadow: true)
    .lookAt(.zero)

let lamp = LightNode.point(color: .custom(r: 1, g: 0.5, b: 0), intensity: 500)
    .position(.init(x: 1, y: 2, z: 0))

3D Text & Billboards

// Always faces camera
let label = BillboardNode.text("Player 1", fontSize: 0.04)
    .position(.init(x: 0, y: 1.5, z: 0))

// 3D extruded text
let title = TextNode(text: "SceneView", fontSize: 0.08, depth: 0.02)
    .centered()
