Hey guys,
I don't know where to start with part 2 of this challenge. Could you point me in the right direction ?
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) {
return // Not sure what to put here
}
}

You don't actually need to return anything from this function. A keyword to tip us off is that the requirements say to "Set the color of the lamp to the new color" so we will need to just set the lamps color property equal to the color value passed into the function.
(Note: be sure and declare self.color so that the function knows we are talking about the class that we are inside of.)
func switchColor(_ color: Color) {
self.color = color
}
