Remove source control for Xcode project

There are three ways. Method 1 will disable source control for all projects. Method 2 will delete the link to a single repository for all projects. Method 3 will remove the link to a repository for a single project. I think Method 3 is the one you are looking for.

1: Through Source Control Management Preferences

In Xcode, choose Xcode-> Preferences, then select Source Control and uncheck Enable Source Control option.

2: Go to Xcode->Preference->Accounts->Repositories and delete them.

3: You can do it manually this way: Show Hidden Files on your Mac and delete all the .svn or .git or .tf files (according to the source control) folders from the project.

Example svn directory:

To remove the current remote just execute this command

rm -rf .git 

1. Quit XCode.
2. Open Terminal.
3. Navigate to the root directory of the project.
4. Type find ./ -name .svn -exec rm -rf {} \;.
5. Open your project.

Your project should be disconnected from all repositories.

NOTE: The command searches for all filenames with extension .svn and removes (recursively and forcefully) all of them.

The steps for Xcode 5 are the same as the steps for Xcode 4:

Just remove the .git directory in the project folder. You should close the project in Xcode first to be safe.
