Bummer problem

I'm stuck here. Can anyone help?

protocols.swift 
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

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

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

Try this:

// 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) {
    self.color = color
  }

  init() {
    self.state = .on
    self.color = .rgb(0,0,0,0)
  }
}
