4,998 PointsProtocols with Methods Code Challenge
What does it mean by "simply set the color of the lamp to the new color"? I am on task 2.
This would be a lot easier if there was the Preview button :(
// 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) {
}
EDIT: I fixed it. The problem was that I had the method outside of the WifiLamp class. It should've looked like this:
// 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)
}
}
(I also needed to add self.color = color)
