title: iOS - How can i get the playable duration of AVPlayer
body: <p>The MPMoviePlayerController has a property called playableDuration.</p>
  
  <blockquote>
    <p><strong>playableDuration</strong> The amount of currently playable content (read-only).</p>
    
    <p>@property (nonatomic, readonly) NSTimeInterval playableDuration</p>
    
    <p>For progressively downloaded network content, this property reflects
    the amount of content that can be played now.</p>
  </blockquote>
  
  <p>Is there something similar for AVPlayer?
  I can't find anything in the Apple Docs or Google (not even here at Stackoverflow.com)</p>
  
  <p>Thanks in advance.</p>
