Referencing IBOutlet to its class or to file's owner

In this Mac App, I have an IBOutlet (which is defined as instance of a subclass of NSView).

When I connect the IBOutlet to the code, referencing as file's owner, it works OK.

But if I reference to the class, it crashes, when I access a specific IBOutlet (but other IBOutlets are accessed just before it without crashing).. The IBOutlet turnPageControl is defined as instance of subclass of NSView.

Note: I have implemented several init methods:

override init(window: NSWindow!) { }

required init?(coder: (NSCoder?)) { }  // Yes, (NSCoder?)

convenience init(parameters) {
  // loading from nib
}

override func windowDidLoad() {
   super.windowDidLoad()
   // Access turnpageControl

I get those calls before crash:

init(window:)
init(parameters:)
init(window:)
windowDidLoad() -> crash inside on accessing the IBOutlet 
                       for turnPageControl.isHidden = true

Is there any reason to this ?

Thinking twice, that seems logic. When loading explicitly from nib, reference should be file's owner.

In other cases, I just init from storyboard, so I have to reference the class.
