Silly Challenge


Im stuck on this challenge its so simple and I feel stupid for not knowing it but I don't know what it means in the second part

Jennifer Nordell

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

enum LightState {
  case On, Off

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

class WifiLamp: ColorSwitchable {
  let state: LightState
  var color: Color
   func switchColor(color: Color) {
   Color.HSB(0, 0, 0, 0)


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

Your switchColor method should look like this:

func switchColor(color: Color) {
    self.color = color

Thank You
