That never happened on Xcode 6.xx, just when I updated to Xcode 7 it occurred, Please provide me with any suggestion or answer as soon as possible.

Answer 1

Enter the required ccredentials or select another authentication method. "Authentication" is a drop-down menu where you can select "User name and Password" or "SSH Keys".

I use SSH Keys, select that option and click "OK".

Some form of authentication has always been required to push to a repository.
