Am I not assigning it right?

Is my way of assigning the function to the doneButton not correct?

buttons.swift 
import Foundation

enum UIBarButtonStyle {
    case Done
    case Plain
    case Bordered
}

class UIBarButtonItem {

    var title: String?
    let style: UIBarButtonStyle
    var target: AnyObject?
    var action: Selector

    init(title: String?, style: UIBarButtonStyle, target: AnyObject?, action: Selector) {
        self.title = title
        self.style = style
        self.target = target
        self.action = action
    }
}
enums.swift 
enum Button {
    case Done(String)
    case Edit(String)

    func toUIBarButtonItem() -> UIBarButtonItem{
    switch self {
case .Done : return UIBarButtonItem(title: "Done", style: UIBarButtonStyle.Done , target: nil , action: nil) 
case .Edit : return UIBarButtonItem(title: "Edit", style: UIBarButtonStyle.Plain , target: nil , action: nil)
}}

}

let done = Button.Done("Done")
let doneButton = done.toUIBarButtonItem

Yes you are missing

()

it should be 

let doneButton = done.toUIBarButtonItem()
