title: Unable to Document Header File with Doxygen
body: <p>I'm attempting to generate documentation for a header file that just contains some constants and I'm not able to generate it.</p>
  
  <p>As suggested in the <a href="http://www.doxygen.nl/manual/faq.html" rel="nofollow noreferrer">doxygen manual</a>, I've tried adding the <code>@file</code> keyword to a comment block and still no luck.</p>
  
  <p>What am I missing?</p>
  
  <p>Here's a snippet:</p>
  
  <pre><code>MyFile.h
  
   /**
   @file 
   my super important documentation.
  
   @author Julian Builes
  */
  typedef NS_ENUM(NSUInteger, HTTPCode) 
  {my code ...}
  </code></pre>
  
  <p><em>background: it's an iOS project using xcode 6 and doxygen 1.8.9.1</em></p>
  
  <p>EDIT: As per Albert's suggestion, I'm attaching a <a href="https://www.dropbox.com/s/1mchtk74ldd40u1/Archive.zip?dl=0" rel="nofollow noreferrer">sample project</a> that exemplifies the problem I'm experiencing.</p>
