title: Xcode - build setting "EXCLUDED_SOURCE_FILE_NAMES" not working
body: <p>I am trying to exclude some .swift and .storyboard files from my project (Xcode9) for release build using <code>EXCLUDED_SOURCE_FILE_NAMES</code>.
  But its not working for me.</p>
  
  <p>Is it possible to give any folder name to exclude it completely?
  How to give multiple files and folder name?</p>
  
  <p>It is not working if I give path like <strong><code>../ForlderName/*</code></strong>.</p>
  
  <p>Folder is at the same level as my project.</p>
  
  <p>Is it possible to exclude sub-folders files as well?</p>
  
  <p>I am able to exclude if my hierarchy is </p>
  
  <pre><code>MyProject Folder
   |_
     MyProject Folder 
      |_FolderToBeExcluded
  </code></pre>
  
  <p>If I gave FolderToBeExcluded/* it is working but file in FolderToBeExcluded's subfolders are not getting excluded.</p>
  
  <p>If my heirachy is like this (ie folder to be excluded and project folder both at same level)</p>
  
  <pre><code>FolderToBeExcluded
  MyProject Folder
   |_
     MyProject Folder
  </code></pre>
  
  <p>If I give <strong>../FolderToBeExcluded/<em></strong>
  or $(SRCROOT)<strong>/../FolderToBeExcluded/</em></strong>
  both are not working</p>
  
  <p>If I give directly any one of the file name which is to be excluded it is getting exclude without giving full path.</p>
  
  <p>Is it the limitation of <code>EXCLUDED_SOURCE_FILE_NAMES</code>?</p>
