You're referring to a "window" instance variable that NSWindowController does
not define, so I assume you defined it yourself. If so, that's a mistake.
You're supposed to refer to the "window" property -- self.window.
In IB, when you connect what looks alike a "window" outlet, you're actually
connecting the NSWindowController's private "_window" ivar (or perhaps, these
days, it's connecting the "window" property, I don't know). That means your
separately-defined "window" ivar won't get connected and will always contain
nil. You should get rid of this ivar from your subclass.
The other difficulty you're running into is that by design the window is not
created immediately when you create a window controller. (You say of your code,
above, that it creates a window from a XIB. It doesn't. It only creates a
window controller.)
Instead, the window is created the first time something refers to the window
controller's "window" property (e.g. 'self.window' if it's referred to from
within the window controller itself). At that point, the NIB is instantiated,
the window created, and 'windowDidLoad' is invoked.
