title: Suppressing warnings in Xcode 7
body: <p>Until now in Xcode 6 I was able to suppress warnings for some external libraries by using pragma directives, like this:</p>
  
  <pre><code>#pragma clang diagnostic push
  #pragma clang diagnostic ignored "-Wdocumentation"
  #import "SwiftToObjectiveC-Swift.h"
  #pragma clang diagnostic pop
  </code></pre>
  
  <p>Since I updated my project to Xcode 7 this directives seem to do nothing, I get all the documentation warnings that are on SwiftToObjectiveC-Swift.h.
  Anyone has an idea what it could be the problem?</p>
  
  <p>Thanks! </p>
