If it doesn't conform then what doest it do?
// Declare protocol here
protocol ColorSwitchable {
func switchColor(_: Color)
}
enum LightState {

}
enum Color {
case rgb(Double, Double, Double, Double)
case hsb(Double, Double, Double, Double)

13,092 PointsYou omitted the internal name "color" as well. And you need that in the initial function (protocol)
Then, when you call it, no need to have it inside the init method, just inside the class. And there you just let the swift know that the var color needs to be the color given to the function.
Like so:
// Declare protocol here
protocol ColorSwitchable {
func switchColor(_ color: Color)
//this is what you missed^
}
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)
}
// and now you call the function
func switchColor(_ color: Color) {
self.color = color
}
}
Hope this helped! Keep up the good work and don't forget to mark the correct answer.
