Hello guys, lets get back to our YouTube application today by building out the feature that allows users to watch video. I'll start off by showing you guys how to animate the video player onto the screen. Next we'll look at how to include an AVPlayer into our video view to actually start playing our video clip. We'll continue with implementing the other video player controls in the next video. Have fun.
