Is there a way to allow Windows users to access an XCode Project via GitHub

  github, swift, windows, xcode

I am currently doing a group project for my Computational Physics module at University. The submission must be as an XCode project and using a GitHub Repository. Two of the members of the group (of whom i am not one) have Windows and no access to Swift and XCode subsequently. Is there a way in which they could open and edit the project via an online compiler and return it to GitHub as a commit?
