The preview errors button is not working, could someone tell me what is wrong with this code?

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 {
  let state: LightState
  var color: Color

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

Protocol methods cant have bodies so it should look like this...

protocol ColorSwitchable {
  func switchColor(color: Color)  
}
