title: OpenCV IOS Swift 2 :How to implement the CvVideoCameraDelegate protocol process Video Frames
body: <p>Okay so I've been using OpenCV and want to use it for IOS with Swift 2.0... I successfully implemented it and I tested it with a few functions/examples, it worked fine! But The application in thought I have is a Live Camera object detection. So using a cascade classifier I will do this, but the thing I have trouble with is setting up the CvVideoCameraDelegate protocol with my ViewController; I'm trying to use this <a href="http://docs.opencv.org/2.4/doc/tutorials/ios/video_processing/video_processing.html" rel="nofollow">tutrial/example</a> to set it up....
  But I'm having trouble trying to set it up in swift.... Can someone please advise the correct way to set it up?</p>
