Stuck on a code challenge! Enum Methods

Sorry for my ridiculous attempt at coding this stuff. It looks and feels so wrong. Can someone help me out so I'm not stuck on this all day tomorrow?

buttons.swift 
// Example of UIBarButtonItem instance
// let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)

enum BarButton {
    case done(title: String)
    case edit(title: String)
}
    func button() -> UIBarButtonItem {
        switch self {
            case .done(title: <#T##String#>)
                return UIBarButtonItem(title: <#T##String?#>, style: <#T##UIBarButtonItemStyle#>, target: <#T##Any?#>, action: <#T##Selector?#>)
            case .edit(title: <#T##String#>)
                return UIBarButtonItem(title: <#T##String?#>, style: <#T##UIBarButtonItemStyle#>, target: <#T##Any?#>, action: <#T##Selector?#>)
        }
    }
}

let done = BarButton.done(title: "save")
let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)
let button = BarButton

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

Hi Martel!

Hope this helps:

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