How does Xcode know who the project was “created by”?

Question

Whenever a new file is added to the project, Xcode adds the following lines of comments on top.

//  Created by {my name here} on 8/4/11.
//  Copyright 2011 _         


        

Answer 1

It uses you own information from the address book.

Got to:

System Preferences --> Users & Groups --> choose current User --> and press Open at Address Book Card.

There you will find you own information used in xcode.
