title: Can I have multiple Xcode versions installed?
body: <p>Is it possible to have more than one version of Xcode installed at the same time? </p>
  
  <p>If so, please post any tip, tricks, or potential issues to watch out for.</p>
  
  <p>EDIT:</p>
  
  <p>The reason I want to install multiple versions is to try out the new sdk beta, but if the new Xcode is buggy I want to be able to use the older version for my existing projects.</p>
