I’m starting loose trust on head first

Apparently Xcode and Github are not friends: Book title Head first iPhone and iPad development 3rd edition

I am not able to get project in chapter-1 for Xcode via
'https:// github.com/dpilone/Head-First-iPhone-iPad-Development-3rd-Edition.git'

If I download the file from url all the activities mentioned in 3rd edition are already done in the project.
