Remove Delegate/Observer.
Delegate should be declared in RTCPeerConnection.h
Observer should be declared in RTCPeerConnection+Private.h

[hjon_webrtc, 2016/02/04 00:58:37]

Done.

Am I also understanding/guessing correctly that the Observer implementation
should be in RTCPeerConnection.mm rather than in its own file?

Yep
