[Help!] What is wrong with my Enum Syntax?

Im not sure what the correct syntax should be when assigning an associate value, please help!

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
    }
}

let done = UIBarButtonStyle.Done ("Done")
enums.swift
enum Button {
    case Done(String)
    case Edit(String)
}

Hi Sheng,

You want to put this code inside the enums.swift file. In there you will find an enum called Button with the Done value option. You create the constant called done then include an associate value, as you have done, after the enum. That could look like:

enum Button {
    case Done(String)
    case Edit(String)
}

let done = Button.Done("Done")

I hope that helps,

Steve.

No problem! :+1:
