title: Fail when i use Bridging Headers in swift frameworks
body: <p>I am doing a swift framework and i want to use old objective c classes. For this, i use the bridging headers method but when i try to build appears this error:</p>
  
  <pre><code>&lt;unknown&gt;:0: error: using bridging headers with framework targets is unsupported
  </code></pre>
  
  <p>I added my {PROJECT}-Bridging-Header.h to Objective-C Bridging Header in Swift Compiler - Code Generation</p>
  
  <p>How can i solved it?</p>
  
  <p>I did in applications and runs Ok, but in this framework no</p>
  
  <p>Thanks</p>
