How can I move files & folders using git in Xcode 4?
You shall not move files in a GIT repository using the Finder. You'd better use the move command from shell.
You then have to manually redresh links in XCode (or remove/add files again).
Moving a file is similar to the unix 'mv' command, with the 'git prefix:
git mv path destination
(use -f to override destination... with caution)
After you have made all your changes in the Finder, open a terminal window and navigate to your project's directory:
cd path/to/project
then run this command:
git add --all
This command will stage all of the changes and Xcode should be able to resume its management of the repository from here.
