title: Get Volume of AVPlayer in iOS
body: <p>There are plenty of questions asking how to <strong>set</strong> the volume of an <code>AVPlayer</code>, but <em>how do you get the current volume of the player in iOS</em>?</p>
  
  <p>For example, I am trying to fade a song out from its current level. I could save the volume elsewhere and refer to it, but would rather read the value directly from the AVPlayer.</p>
