iOS Swift 2.0 Protocols Swift 2.0 Protocols Protocols With Methods

Don't even understand what this is asking.

It keeps telling me to make a method, doing it just like we did it in the video but it is currently not working.

// Declare protocol here
protocol ColorSwitchable {
  func color() -> (color: Color)

enum LightState {
  case On, Off

enum Color {
  case RGB(Double, Double, Double, Double)
  case HSB(Double, Double, Double, Double)

class WifiLamp {
  let state: LightState
  var color: Color

  init() {
    self.state = .On
    self.color = .RGB(0,0,0,0)

Hey Raleigh, you almost got it just wrote your requirement incorrectly.

Where you wrote func color() -> (color: Color). It's suppose to be func switchColor(color: Color)

Why? Well 1. The instructions state the functions name needs to be switchColor. 2. The instructions also state that the functions only needs to take a Color argrument. Which means your parameters need to take a Color object. What you did was say the color function takes NO parameters and RETURNS a color object.

Hope that helps! Ask again if you're still confused :)
