No default Port

[ranguh]

There are no default args for IP address or Port address on Chapter 6 Xcode project's RoboCatClient.

I had to go to Product >> Scheme >> Edit Scheme, then select RoboCatClient and typed 127.0.0.1:45000. Until I did this the client would open but would only display a blue screen because it never connected to the server.

Anyone else just downloading the files would have to do the same to get the client working it looks like.
