title: How hide AVFoundation debugging logs?
body: <p>OS X 10.10 and XCode 6.1.1.</p>
  
  <p>Probably I messed up something in the project settings, as now unnecessary logs associated with AVFoundation.framework appears in the console. The first block appears while init, settings and playing music in AVPlayer.</p>

  <p>These logs appear when I pause or play.</p>

  <p>There's also a lot of other notices that I do not need, because all these errors are not critical, and I have never seen them before. I don't understand - how to disable this debug logs? What is it?</p>
