initWithWindow: is the designated initializer which is why the template has it vs one other of the init methods, but it doesn't mean you have to use it. It's not there to tell you that you need to call it, it's there so you can add initialization-time code as needed.
The easiest thing to do to get a window controller to load from a nib automatically is just implement -windowNibName. (In 10.10 you won't need to even bother if the xib is named the same as the class.)
Nothing magical going on. You (as an example) call alloc] init], it calls initWithWindow: passing nil (because it's the designated initializer). You ask for the wc's window at some point, it realizes it doesn't have one, sees windowNibName, loads from the nib, and calls windowDidLoad. Baddabing badda boom.

I thought the controller was supposed to mediate interactions between the UI and any models or other controllers, according to MVC; other code shouldn't have to worry about how or where the window comes from.
