What am I doing wrong when implementiong method to change color conforming to interface?
// 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 {
func switchColor(_ color: Color) {
color = Color.rgb(1,1,1,1)
}
let state: LightState
var color: Color
init() {
self.state = .on
self.color = .rgb(0,0,0,0)
}
}

Looks like the only thing you need to change is where you are assigning color in the method. self.color = color is what you're looking for, because we want to set the color property of the class with the argument passed in which should already be a Color object.
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) {
self.color = color
}
}
