Your external parameter name is not used in this challenge so you need to use an underscore in your method signature.
Also we are changing the color of the WifiLamp by a color we pass into the function as a variable/parameter. So you would need to show this within the body of your function by setting the self.color to the color you pass in as a parameter.
Only this line of code would be placed within the body of the WifiLamp class.
func switchColor(_ color: Color) {
self.color = color
}
It may help you to check your code in an xcode playground and check for errors there so you don't have to ask for help on each challenge.
Also if you like the answers I am helping you with, you should mark them as best answer so I receive some credit for helping you. Good luck!

you're off to a great start. It's mostly the return statement that's on the wrong place.
here's how you switch color in your switchColor method:
switch color {
case .RGB: ... do something
case .HSB: ... do something
}

2,660 Pointscan you be more explicitly, because i dont really get what should i write to change the values... and where should the return go?
