iOS Development Techdegree Graduate 15,223 PointsHey Mohammad,
You are pretty close!
Inside your method you are assigning _ to Color.self
the task is asking you to just assign the color you pass into the function to the color property on the class.
class WifiLamp: ColorSwitchable {
let state: LightState
var color: Color
func switchColor(_ color: Color) {
self.color = color //Here I am just assigning the color parameter to self.color (WifiLamp.color).
}
// I can rename the properties to make it a bit more clear
class WifiLamp: ColorSwitchable {
let state: LightState
var wifiLampsColor: Color
func switchColor(_ parameterColor: Color) {
self.wifiLampsColor = parameterColor //here it is more clear on what exactly is happening.
}
Hope that helps! Happy Coding!
