Question if Swift works on Linux right now what are the chances that it also works on Windows's new built in Linux (WSL2)?
But i guess the pure Windows ecosystem is rough on the edges right now, but doable. And in WSL(1) things have worked pretty the same as in Linux.
Just download the packaged binary distributed on their site, and you are ready to go.
(Oh, a note; its not the tensorflow branch, if is thats what you want)
