Other platforms like Codename One ( https://www.codenameone.com/blog/comparing-xamarin-and-codename-one.html https://www.codenameone.com/blog/comparing-xamarin-and-coden... ) can provide things like Java support for iOS, Android, Windows etc. without a physical Mac. They do it thru a cloud build process. It works properly because of the lightweight architecture. Obviously the goals of Codename One and Xamarin are different whereas Codename One tries to be WORA, Xamarin doesn't.
