title: Xcode how to exclude FOLDERS from compilation?
body: <p>I saw <a href="http://lists.apple.com/archives/xcode-users/2009/Jun/msg00153.html" rel="noreferrer">this</a> and answers in stackO, but didn't find how to exclude folders. </p>
  
  <p>I have 3 folders with a lot of .h , .m and .mm and i need to exclude them temporary, but not to remove references. How can i do that?</p>
