title: Passbook , showing an .pass in an app
body: <p>All, 
  I have been reading from Apple documentation and I have found info to show bits of a pass and changing a pass in an app. But is there a way the .pass zip can be stored in XCODE and shown in a pop up view controller ? </p>
  
  <p>I have figured this out, but I doesnt work. </p>
  
  <p>Any advice ?? </p>
  
  <pre><code>var pkfile : NSData = NSData(contentsOfFile: "Event.pkpass")!
          var pass : PKPass = PKPass(data: pkfile, error: nil)
          let vc = PKAddPassesViewController(pass: pass)
          self.presentViewController(vc, animated: true, completion: nil)
  </code></pre>
