Now that we've started the initial design of our <b>Episode Player</b> and figured out how to launch it inside of our application, it's time to finish it up by including the rest of our UI elements. In today's lesson, we add in the playback controls at the bottom by taking advantage of a few horizontal <b>UIStackViews</b>. You definitely have to play around with the UIStackView component to see what it allows you to do and what are the configuration options. Enjoy.
