I hope someone can help me. Thanks in advance.

// 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)

}

Hey Maarten!

There's a piece of the challenge text that your code is missing. "In the implementation of the method, simply set the color of the lamp to the new color."

  func switchColor(_ color: Color) {
    self.color = color
  }

Hope it helps!
