CFSocket doesn't currently support peer addresses for SOCK_DGRAM sockets. You can file a bug about this if you like, but this behavior is generally consistent with that of the underlying BSD layer. Since you are the one performing the connect, you can simply hold on to the address you use rather than asking the CFSocket for it. In fact, you don't even need to connect when you are using a SOCK_DGRAM socket.
