Im pretty sure I am lost on this objective.

Without judging how far off I am, can someone help show me how this is supposed to be properly set up.

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: Color) 
  ( RGB: Double, Double, Double, Double)

  }
}

Here you go:

protocol ColorSwitchable {
    func switchColor(color: Color)
}

. . .

class WifiLamp: ColorSwitchable {
    let state: LightState
    var color: Color

    init() {
        self.state = .On
        self.color = .RGB(0,0,0,0)
    }

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