title: What OSX/XCode version control system should I use for iPhone development?
body: <p>I've been developing my first iPhone app part-time and would like to start using a more rigorous form of version control than I've been using over the past four months, i.e. copying source code folders to another directory and time stamping them.</p>
  
  <p>I've used SourceSafe and Team Foundation System but I don't have a good idea of what version control systems (VCS) are available for the Macintosh. I've seen ads on SO for a Subversion front end but would like some other options.</p>
  
  <p>Here's a list of my initial requirements:</p>
  
  <ul>
  <li>Runs locally under OS X Leopard 10.5.7</li>
  <li>Integrates with XCode 3.1.3 (if no integration, user-friendly interface)</li>
  <li>Basic VCS features - check-in comments, branching, pinning</li>
  <li>Advanced VCS features like build automation or reports would be nice but not critical at this time</li>
  <li>Ability to handle multiple developers down the road (6-12 months)</li>
  </ul>
  
  <p>Thanks in advance for the help.</p>
