title: Creating group in Xcode does not create folder in file system -- why?
body: <p>In Xcode IDE when I add a new group named 'Organizer' inside the default Classes group it is getting created. But when I physically see the folder in the Finder, that new group Organizer is not showing as a folder.</p>
  
  <p>Actually I want to maintain the sources in a particular structure i.e, how it exists in the XCode view.</p>
  
  <p>What should I do to achieve this?</p>
