title: RTCReporting & pancake.apple.com errors
body: <p>Yesterday I updated Xcode to Version 5.1 (5B130a); the simulator's version now reads Version 7.1 (463.9.41).</p>
  
  <p>Today I started getting these weird errors when beginning playback using AVPlayer. I have never seen any such errors in the past, can't find any info about them, and have no idea what they mean. They are not fatal and I haven't noticed any ill effects from them. But…</p>
  
  <p>What is RTCReporting and how did it get into my project?</p>
  
  <p>What does pancake.apple.com have to do with anything?</p>
  
  <p>Etc. Thanks.</p>

  <p>UPDATE: I had not previously noticed any harm from this, but now my app is hanging (in simulator) for about 5 seconds while I'm just getting an item ready for playback (before I've pressed play). Here's what the debug navigator shows if I press pause during the hang:</p>

  <p>When the app unfreezes after 5 seconds, just the following is logged:</p>
  
  <pre><code>RTCReporting: resolve from http://pancake.apple.com/bags/hls?version=4.12
  </code></pre>
  
  <p><strong>A note on "answers":</strong></p>
  
  <p>I'm looking for non-obvious explanation related to the questions I posed.</p>
