Important: This document, which describes Xcode 3, has been superseded in Xcode 4 by the chapter “Repositories, Snapshots, and Archives” from the Xcode 4 User Guide.
A source control system (also known as a source control management system or an SCM system), provides a repository for source files and a high-level interface to the changes made to them over time. In general terms, a source control system stores every change made to a file since it became part of the system. Source control systems can be used by individuals, but they are generally used by teams of developers who work on the same projects. A source control system allows several developers to keep track of the changes the team has made to the files that it stores.
Source control systems provide a command-line interface through which you can perform all the source control operations they support. However, Xcode provides an easy-to-use interface for the most popular source control systems. Through Xcode, you can browse repositories, check out projects, and track changes made to source files.
This document provides an overview of source control and describes how to work on projects managed under source control through the Xcode user interface.
To get the most out of this document, you should be familiar with the Xcode user interface and the structure of Xcode projects.
Consult Xcode Workspace Guide first if you’re not familiar with the Xcode user interface.
