Status

[!IMPORTANT] * The bindings to Dawn are complete and a subset of them have been well tested * The Wasm bindings are still in early development.

Swift WebGPU Bindings for Dawn and Web

A set of Swift APIs for using WebGPU across multiple platforms.

Goals

The goal is to be able to write GPU code, using Swift, that works everywhere, including (eventually) the web.

The initial implementation is a Swift binding to Google's Dawn library.

Non-Goals

Swan is not intended to be a full rendering engine. It does not provide any rendering primitives beyond what is in WebGPU spec. For example, we do not specify a 4x4 matrix implementation, although we may use one in our examples.

Quick Start

The following snippet shows how to add Swan to your Swift package:

// swift-tools-version: 6.1
import PackageDescription

let package = Package(
    name: "YourApp",
    dependencies: [
        .package(url: "https://github.com/adobe/swan", from: "0.0.1")
    ],
    targets: [
        .target(
            name: "YourApp",
            dependencies: [
                .product(name: "Logging", package: "swan")
            ]
        )
    ]
)

Usage

You can run the demos by:

swift run GameOfLife
swift run BitonicSort

Alternatives

• swift-webgpu is another binding for WebGPU that takes a different approach.

	swift-webgpu	swift-wgpu (this project)
Dawn binding generation	Swift code generated from dawn.json acts as wrappers	C headers from Dawn are used directly in conjunction with an apinotes file generated from dawn.json
JavaScript binding generation	N/A	In progress
