alt Hacker News> Swift on Windows is being used by The Browser Company to share code and bring the Arc browser to 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.
FWIW, Swift for Windows is a thing (https://www.swift.org/install/windows/), and there's a new Windows-specific workgroup: https://www.swift.org/blog/announcing-windows-workgroup/
