If this path is wrong the file will turn red indicating that it cannot be located. Define the required source tree then close and reopen the project to resolve the reference. To redefine your source trees close all projects redefine your source trees and open the projects again. Xcode resolves the source file paths using the new source tree locations. SOURCE CONTROL Source control systems work by storing the master copies of your project files in a repository. A repository is a database of files. A repository might be on the same file system or on a remote system. Xcode might access a repository using direct file access or by sending requests over a network to a source control server. Regardless of the configuration you interact with the source control system through Xcode or via a source control client installed on your system. A file stored in a repository is called a managed file. When you want to work with a managed file you check out the file from the repository. The copy of the file you checked out is called the working copy. If you make changes to the working copy you later check in the file to record those changes in the repository. After the changes have been recorded other developers can check out the file to incorporate your changes into their working projects. You can compare your working copy with other versions in the repository to see exactly what has changed. You can also check out an earlier version of any file and use it instead maybe because you don t like the changes made by another developer.

CVS was the reigning king of open source control systems but has since been usurped by Subversion. An installation of .
