RTCReporting & pancake.apple.com errors

Yesterday I updated Xcode to Version 5.1 (5B130a); the simulator's version now reads Version 7.1 (463.9.41).

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…

What is RTCReporting and how did it get into my project?

What does pancake.apple.com have to do with anything?

Etc. Thanks.

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:

When the app unfreezes after 5 seconds, just the following is logged:

A note on "answers":

I'm looking for non-obvious explanation related to the questions I posed.

回答1:

This seems to be a problem with trying to play videos on the simulator. I've had this problem for months now, and just ran into it again today when I was trying to play video on my simulator.

The solution, while not great, is to use an actual device instead of the simulator for testing video playing.

回答2:

I always encounter this issue if I've got an Exception Breakpoint enabled when I play a video. If I disable it then it works fine. I've submitted a bug report to Apple also.

回答3:

This seems to be a problem with trying to play videos on the simulator. I solved by quiting other audio or video playing from my system.
