3,309 PointsSimply, the challenge didn't ask you to conform the class WifiLamp to the protocol ColorSwitchable. So, if you clean that part and, as already pointed out by Halil Bayrakci, you fix the method switchColor omitting the first label, it will work.
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)
}
}

3,884 Pointsyour code is right but the challenge specifically wants your argument underscored :)
For the sake of this challenge, make sure your external argument label is omitted by using an underscore.
