Now that the spec is nearing completion, I thought I'd share swift-webgpu; a Swift interface for the upcoming WebGPU API.
Although originally intended for the web (as a successor to WebGL), a native version of WebGPU is also being worked on alongside. Under the hood, it maps to an appropriate platform API (Metal, Vulkan, Direct3D etc.). Currently, swift-webgpu is based on (and generated from) Google's Dawn implementation.
I've developed a few demos in Swift and tested on Mac, Ubuntu, and (albeit with some additional tweaks) Windows!
I am still anticipating some breaking changes to come (Dawn itself is not yet fully stable, although they are aiming for a v1 release soon). One slightly annoying thing about the Swift API at the moment is that most integers are explicitly defined as either 32 or 64 bit unsigned, so as a user, you find yourself having to perform a lot of conversions from Int. I'm not sure if there's a decent solution to this without introducing some unsafeness.
Whilst the API is fairly low level (compared to a game engine for example), it may be a useful building block for various creative / graphical projects in the future!
