That's progress over where it was a year ago. But the almost complete absence of packages that run on Windows makes the progress made so far more of a curiosity than a usable option--alas. I'd use Swift in a heartbeat if it had even a semblance of a decent ecosystem on Windows.
Arc is no longer being developed ( http://www.newswarner.com/2025/05/27/the-browser-company-exp... ) and AFAICT their efforts to port Swift to Windows for its sake have been cancelled.
