Reference main NSWindow in AppDelegate using Storyboard?

Question

I am attempting to set an outlet for the main window of my app in my App Delegate, then connect it within Interface Builder. I create the outlet within my App Delegate easily:

@IBOutlet weak var mainWindow: NSWindow!

However there's no way, within interface builder, for me to connect a referencing outlet to the App Delegate. Instead, I can only connect it to the Window Controller, which I hope this picture shows:

The first object is the Window Controller and the second object is the First Responder, however the App Delegate object is missing. The menubar has the App Delegate object:

And I can connect anything from the menubar to any outlets in the App Delegate.

I figure I can access the window object by using:

NSApp.windows[0]

But that seems prone to error, especially if I have more than one window.

I dont know if this is correct way of doing, but this will solve your problem.

Decalre a NSWindow property in AppDelegate

weak var window: NSWindow!

and set the property in something like windowWillLoad of the NSWindowController

(NSApplication.sharedApplication().delegate as! AppDelegate).window = self.window

You will have to subclass NSWindowController to define windowWillLoad
