There are some pretty horrible instructions out there for renaming projects in XCode. Is there no easy way to do this?
In Xcode 4 try this:
⌘+1, click the blue node with the project name, wait a second, click again (the name becomes editable). That's it.
In the menu bar choose Project -> Rename...
It'll do all the hard work for you and rename everything that needs renaming apart from the folder that the project is in.
In XCode 4, select the project name at the top of the documents list on the left and hit enter, rename it, and then XCode will show you a list of files that will be altered, as well as allowing you to take a snapshot.
