title: _BSMachError while running Stanford's CS193p Smashtag app
body: <p>I downloaded the Smasthag demo app from <a href="http://web.stanford.edu/class/cs193p/cgi-bin/drupal/">course's site</a>. Project builds fine (after small changes in Twitter, TwitterRequest etc. classes, because I use the latest Xcode 7b4) and works fine on simulator (I also had to add <code>NSAppTransportSecurity</code> key to <code>info.plist</code>), but not on a device - it doesn't fetch tweets . I tested it on both iPhone 6 with iOS 9 Public Beta and iPad 2 with iOS 8.4. Moreover, when app is running in the simulator and I change hashtag to search, whole tableView reloads with new tweets, but in the console I get this: </p>
  
  <pre><code>2015-07-23 03:24:15.560 Smashtag[25991:4344251] _BSMachError: (os/kern) invalid capability (20)
  2015-07-23 03:24:15.560 Smashtag[25991:4344251] _BSMachError: (os/kern) invalid name (15)
  </code></pre>
  
  <p>App still runs fine, but this error bugs me. I couldn't fine anything about this _BSMachError in google (just one lonely Indonesian tweet). I can't also get why app doesn't fetch tweets on a device.</p>
