Can't disable UIBarButtonItem

I'm instantiating my UIBarButtonItem as a property of my class:

var copyBarButtonItem: UIBarButtonItem {
    return UIBarButtonItem(title: "Copy", style: UIBarButtonItemStyle.Bordered, target: self, action: "copyButtonClicked:")
}

The button is added to my toolbar:

var toolbarButtonItems:Array<UIBarButtonItem> = [spacer, self.copyBarButtonItem]
self.setToolbarItems(toolbarButtonItems, animated: false)

All works fine. The only problem is that I can't disable the button!

I've tried:

self.copyBarButtonItem.enabled = false

No luck. I've tried the setEnabled method, but that doesn't seem to exist for UIBarButtonItem.

You are using computed property.Each time your self.copyBarButtonItem will give different instance.Use instead

var copyBarButtonItem: UIBarButtonItem = UIBarButtonItem(title: "Copy", style: UIBarButtonItemStyle.Bordered, target: self, action: "copyButtonClicked:");

you need to define as stored properties.Stored Properties are just variable in swift
