title: How to add files to a .bundle file in xcode
body: <p>I am working on an iOS application that I did not create and I would like to add some audio and image assets to the project. Right now these are all located in a <code>.bundle</code> file and accessed like this:</p>
  
  <p><code>
  [[NSBundle mainBundle] pathForResource:@"MyBundle.bundle/some_audio" ofType:@"m4a"]
  </code></p>
  
  <p>My question is, how do I add new assets to <code>MyBundle.bundle</code>? I have located <code>MyBundle.bundle</code> in the project navigator and on the filesystem but I can't figure out how to add files.</p>
