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

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
}
}
