avkit player swift xcode - Looking for a tutorial

I simply want to make something very similar to the Headspace iOS app. I think I can get mostly there but I simply can't figure out where to begin in order to have two main elements - a button that is pressed and plays a video or audio. A tutorial or simple explanation would be great if anybody has encountered one or thinks it's simple to achieve.

Any help would be greatly appreciated.
