To make playing audio and video files as simple and straightforward as can be, Apple has created the AVFoundation framework. This framework contains a lot of helper classes that provide very low-level control over how iOS plays audio and video files.

In this section, you will learn how to implement a simple video player with AVPlayerViewController from the AVKit framework. You will also implement a more complex audio player with AVFoundation components that play audio in the background and display, on the lock screen, the audio track currently being...
