title: Custom camera in iOS like Snapchat
body: <p>How does Snapchat make a custom UI for the camera, and how do they put a blur over it? I tried to accomplish the blur by putting a BlurView on top of the ImageView that I make into the camera with UIImagePicker, in</p>
  
  <pre><code>override func viewWillAppear(bool {
  super.viewWillAppear(true)
  'UIImagePicker logic'
  }
  </code></pre>
  
  <p>But the imagepicker is not working until I remove the BlurView from the super view</p>
