In the editor below, I've declared a class, WifiLamp, that represents an interface to one of those Internet of Things lamps. The class models state that determines whether the lamp is on or off and a color, represented by the Color enum. For the first step, declare a protocol named ColorSwitchable. The protocol has a single requirement: a method named switchColor that takes a value of Color as an argument. For the sake of this challenge, make sure your method parameter is named color.
// Declare protocol here
protocol ColorSwitchable {
func switchColor() -> (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)
}
}

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