Not sure what to do here

Is this the proper way to implement the function?

protocols.swift
// 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.rgb(0, 0, 0, 0))
  }

  init() {
    self.state = .on
    self.color = .rgb(0,0,0,0)
  }
}

The way this question is worded is a little misleading, you almost have it

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)
  }
}
