The application we will be building is a simple chat application that has the following:
A simple list of
Channels that the user is a part of.
Clicking on the channel will open up the chat view.
You can send and receive messages from this channel in this view.
The storyboard (refer to
Main.storyboard) contains a top-level
NavigationController inside which is embedded the
ChannelListViewController (shows a list of Channels) and
ChannelWindowViewController. (the chat view)
