Unsure as to the syntax I should use and not sure where I can begin the fix. Sorry for being a newb, hope somebody can help! Would really help for sure..
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
}
}
enum Button {
case Done(String)
case Edit(String)
func toUIBarButtonItem()-> UIBarButtonItem.Done {
switch self {
case target: nil
case action: nil
}
}
func toUIBarButtonItem() -> UIBarButtonStyle.Plain {
switch self {
case target: nil
case action: nil
}
}
}
let done = Button.Done("Done")
let doneButton = Button.Done("Done")

I didn't make any change to the 'buttons.swift', so listed below I have the 'enums.swift'.
You just need one method and inside the switch, you need to have a 'case' for each enum. Once you have identified which item, you then return the new UIBarButtonItem with the associated settings.
enum Button {
case Done(String)
case Edit(String)
func toUIBarButtonItem() -> UIBarButtonItem {
switch self {
case .Done(let title):
return UIBarButtonItem(title: title, style: UIBarButtonStyle.Done, target: nil, action: nil)
case .Edit(let title):
return UIBarButtonItem(title: title, style: UIBarButtonStyle.Plain, target: nil, action: nil)
}
}
}
let done = Button.Done("Done")
let doneButton = done.toUIBarButtonItem()
