Answer 1

Note: since June 2016, you can open your demo GitHub project in Xcode directly from the GitHub site!

But you will need the latest Xcode 9, announced at the 2017 WWDC

See "Clone in Xcode"

It's easy to explore code in your browser when you visit a GitHub repository, but you often want to pull that code directly into the appropriate editor and try it out.
For example, if the repository contains an .xcodeproj or .xcworkspace file, you might want to open that code in Xcode.

This is possible starting today with the new "Open in Xcode" button.

That will trigger the git clone for you.

Note: as illustrated in "Unable to see “Open in Xcode” button on GitHub", you also have to be logged in to GitHub in Xcode as well.

In Xcode, navigate to Preferences.../Accounts, select GitHub and enter your login credentials.
