title: Is code coverage already working for Swift?
body: <p>I am trying to setup test code coverage for a Swift application on Xcode 6 Beta 4.<br>
  I was able to do so in the past using ObjectiveC with Xcode 5, however I think I had to call the <code>void __gcov_flush()</code> method, to trigger generation of the .gcda/.gcno files.<br>
  I set both properties for instrumentation and code coverage to <code>YES</code> for the app and test targets.<br>
  However after running the tests, when I look in:<br>
  DerivedData/some subfolders/i386 all I see are files of type:<br>
  .d,.dia,.o,.swiftmodule and so on, but nothing that indicates code coverage.</p>
  
  <p>Therefore I have two questions:</p>
  
  <ol>
  <li>Is code coverage expected to work for Swift using Xcode6 beta 4?</li>
  <li>If yes and it is necessary to flush gcov first, how do I do that
  from Swift?     </li>
  </ol>
  
  <p>Thanks</p>
