title: C4Camera example crashes on XCode 4.6 and XCode 5
body: <p>The main example <a href="https://gist.github.com/C4Tutorials/5399635" rel="nofollow">https://gist.github.com/C4Tutorials/5399635</a> crashes in the simulator with the following error: <code>NSInvalidArgumentException', reason: '*** Can't add a nil AVCaptureInput'</code></p>
