What am I doing wrong here? How do I properly set the color of the lamp to a new Color?

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 } }

WifiLamp(colorSwitchable())

protocols.swift
// 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

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

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

WifiLamp(colorSwitchable())

Everything's great except for this last line:

WifiLamp(colorSwitchable())

If you delete it the editor will be very happy!
