Im probably blinde to the problem so I cant figure this out, I have seen solutions to this challenge and I think that I have done this correctly but obviously not.
// 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: ColorSwitchable {
let state: LightState
var color: Color
func switchColor(color: Color) {
self.color = color
}
}
init() {
self.state = .On
self.color = .RGB(0,0,0,0)
}
}

15,970 PointsHi Magnus,
this one will work. Note that:
1) there was one additional closing bracket in your code, which closed the WifiLamp class too early
2) the challenge asked you to omit the external name for the switchColor method
3) you changed the letters in the words rgb, hsb, on and off to uppercase letters
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
func switchColor(_ color: Color) {
self.color = color
}
init() {
self.state = .On
self.color = .rgb(0,0,0,0)
}
}

17,232 PointsThank you! I have rewritten this challenge, seen the videos and looked at solutions so many times and still not geting it to work that I was ready to give up on this corse.
