What's going on here?

Question

I don't get what I'm doing wrong, been stuck on this for too long, someone help.

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:
          return UIBarButtonItem(title: "Something", style: UIBarButtonStyle.done, target: nil, action: nil)
        case .edit:
          return UIBarButtonItem(title: "Edit", style: UIBarButtonStyle.edit, target: nil, action: nil)
         }

}

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

Hi Michael,

A few small items are preventing this code from passing the challenge:

1) In the button method, the .edit case should return a .plain style (this is requested in the challenge instructions, step 2)

2) The button function is missing the closing curly bracket

3) When you invoke the BarButton method, the instructions want you to bind it to a constant named "button"

Make these fixes and it should work. Here is the corrected code:

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

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

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