import UIKit

enum BarButton { case done(title: String) case edit(title: String)

func button() -> UIBarButtonItem {
    switch self {
    case .done(let title):
        return UIBarButtonItem(title: title, style: .done, target: nil, action: nil)
    case .edit(let title):
        return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
    }
}

}

let button = BarButton.done(title: "Save").button()
