Not understanding what this mean "Bummer! In the body of switchColor, change the color of the lamp to the value provided as an argument"
// 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
init() {
self.state = .on
self.color = .rgb(0,0,0,0)
}
func switchColor(_ color: Color) {
_ = Color.rgb(1,1,1,1)
}
}

Your close, in your method assign self.color to the Color.rbg().
// 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
init() {
self.state = .on
self.color = .rgb(0,0,0,0)
}
func switchColor(_ color: Color) {
self.color = Color.rgb(1,1,1,1) //doing it this way sets your lamp color to rbg(1,1,1,1). You will pass the code challenge but wont actually be able to set the color later.
}
}
instead try setting up your switchColor like I did. Under the class setup can see how it works with the testLamp variable I setup:
// 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
init() {
self.state = .on
self.color = .rgb(0,0,0,0)
}
func switchColor(_ color: Color) {
self.color = color
}
}
var testLamp = WifiLamp() //lamp setup
testLamp.switchColor(Color.rgb(1, 1, 1, 1)) //change the lamp color
testLamp.color //retunrs rgb(1.0, 1.0, 1.0, 1.0)
I hope this helps.
