iOS Protocols in Swift Protocol Basics Protocols With Methods

I'm stumped

I've been at this for an embarrassingly long amount of time and I need some guidance. What do I do next?

protocols.swift
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 {
  let state: LightState
  var color: Color

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

What do the instructions want you to do at this point?

Hi Fredrick,

Assuming you’re at task 2 of 2, it’s asking you first to have WifiLamp conform to the protocol ColorSwitchable

class WifiLamp: ColorSwitchable {
...
    func switchColor(_ color: Color) {}
}

Then it’s asking you to implement, within the class instance method, code that will assign the class property color to the value of the method’s parameter color

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

Does this make sense?

Yes thank you so much, it made it clearer
