Do we have to use Mac computer to run this ? Class should mention how about window computer? Because most people own window ones.

Answer 1

Swift is portable to Ubuntu Linux and you can run Ubuntu Linux in a VM on Windows through a hypervisor such as VirtualBox.

Answer 2

You can use by virtual machine

Answer 3

You need a Mac only for the "Build iOS App" section. The majority of the course can be done using the Soholearn app, and if you want practice on a Windows computer you can use IBM's Swift sandbox for free (Google for it), as this runs in any web browser.

I would add however, there's not a whole lot of point learning Swift if you're not going to have a Mac available, as you can only develop in Swift on a Mac at this present time.
