SwiftBindings.Apple.RealityKit

SwiftBindings.Apple.RealityKit

Native .NET bindings for Apple's RealityKit framework — Apple's high-level 3D rendering, simulation, and AR composition framework. These are not Objective-C proxy wrappers; they use .NET 10's native Swift interop for direct, high-performance calls into Swift APIs from C#.

📖 Full usage guide → — Swift→C# naming, ARView, hit-testing, entity gestures, render/debug options, and the runtime gaps to avoid.

Most of the entity / component / scene / transform surface lives in the underlying RealityFoundation framework and is shipped as a separate SwiftBindings.Apple.RealityFoundation package. This package adds the RealityKit-specific surface (ARView, gesture recognizers, render and debug options) and depends on SwiftBindings.Apple.RealityFoundation.

Installation

dotnet add package SwiftBindings.Apple.RealityKit

Requirements

• .NET 10.0+
• Target framework: net10.0-ios26.2 or higher. The package is compiled against the iOS 26.2 SDK supplement, so your app's <TargetFramework> platform version must be ≥ 26.2 to restore it — an explicit lower TPV (e.g. net10.0-ios18.0) or a bare net10.0-ios whose installed workload defaults below 26.2 fails restore with NU1202. This is the compile-SDK pin, not your app's deployment minimum.
• Deployment minimum is separate — set your app's real minimum OS with <SupportedOSPlatformVersion> (independent of the TFM above). Individual APIs that need a newer OS at runtime are gated by generated [SupportedOSPlatform] attributes; the C# compiler flags a call that isn't valid for your target.
• macOS host for development

Usage

using RealityKit;          // ARView and other RealityKit-specific types
using RealityFoundation;   // Entity, Component, Scene, Transform, ModelEntity…

// ARView and the RealityKit-specific composition surface are bound here; the
// entity-component / scene / transform / animation types come from the sibling
// SwiftBindings.Apple.RealityFoundation package. Refer to Apple's RealityKit
// documentation for the full type surface.

How It Works

These bindings are auto-generated by Swift Dotnet Bindings using .NET 10's native Swift interop via the SwiftBindings SDK.
