Use NSToolBar Outlet xcode 6 and Storyboard?

I am trying to add an outlet into my viewcontroller for a toolbar item in my window controller. I have tried playing around with first responder and bindings but have not been able to find any solutions.

A similar question that was answered provided some insight but no one has mentioned anything about IBOutlets other than still asking how to add them in the comments. The answer has been accepted so i am assuming no one will add to it.

How to use NSToolBar in Xcode 6 and Storyboard?

Incase my question is unclear at all, i would like to be able to add this to my storyboard program

@IBOutlet weak var Mytoolbar: NSToolbarItem!

func enabletoolbar()
{
    Mytoolbar.action = "FunctionIn.ViewController.swift"
    Mytoolbar.enabled = true
}

i ended up doing this in my view controller which seems to work

override func viewDidLayout() {
    var x = self.view.window?.toolbar?.items[1].label
    println(x)
    if(self.view.window?.toolbar?.items[0].label! != "Check")
    {
        toobarediting()
    }
    println("didlay")
}

func toobarediting() {
    self.view.window?.toolbar?.insertItemWithItemIdentifier("Check", atIndex: 0)
}

func toolbarcheck(functiontoset: Selector) {
    var y = self.view.window?.toolbar?.items[0] as NSToolbarItem
    y.action = functiontoset
    if(functiontoset != nil)
    {
        y.enabled = true
    }
}

It seems to allow me to make the tool bar button clickable/unclickable when ever i require it to change it just seems so much more bulky and error prone than

myitem.enable = fale 
myitem.action = nil

is this really the best way for a storyboard based application in osx?
