title: Can't run Lister app sample code (Swift) from Apple's website
body: <p>I tried to download and run the Lister app sample code which was presented at WWDC for the session 406: Integrating Swift With Objective-C. (I am running XCode 6.1 on Yosemite and this is the most updated version of the Lister app from the sample code page in Apple).</p>
  
  <p><a href="https://developer.apple.com/library/ios/samplecode/Lister/Introduction/Intro.html" rel="nofollow noreferrer">https://developer.apple.com/library/ios/samplecode/Lister/Introduction/Intro.html</a></p>
  
  <p>However I was unable to run the app in XCode which are best show in the attached screenshot.</p>
  
  <ol>
  <li><p>The app doesn't have the Run and Stop buttons enabled. They are greyed out. Never had this before for any other app.</p></li>
  <li><p>The icons for the Lister app is not showing. Instead there is this new Settings-like icon which I have never seen and have no idea what it means.</p></li>
  </ol>
