title: Swift Namespacing Issue
body: <p>I have created a class named <code>Bundle</code>, which I'd really like to remain named that way, as it perfectly describes what it's for in my project.<br>
  Now, I'm using Swift's <code>Bundle</code> in some code and now those names are conflicting. I had this issue before when I created the class <code>Set</code>. I was able to solve that by putting <code>Swift.Set</code> when I wanted to use the standard <code>Set</code> class, as I found in <a href="https://stackoverflow.com/a/25232124/3397217">this answer</a> on exactly this matter.<br>
  I also tried to apply that solution my <code>Bundle</code> problem, but Xcode complains:</p>
  
  <blockquote>
    <p>Module 'Swift' has no member named 'Bundle'</p>
  </blockquote>
  
  <p>Any idea why it does work for <code>Set</code>, but not <code>Bundle</code>?<br>
  Thanks!</p>
