iOS Protocols in Swift Protocol Basics Protocols With Methods

how do I implement the method inside the class Wifi Lamp?

i cannot use the function inside the class.

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

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

    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 }}

You dont need to use it. You need just To write what this function will do when you will call it on an instance.

Oleh Kim, please put your Answer under "Add an Answer" rather than "Add Comment". It makes it easier for people to know the problem has been solved so they don't get e-mails redirecting them to a page with an already solved issue. Also, you can use (three backticks) Swift ... (three more backticks) to write code in your post:

// This is swift code. It's easier to read because of the color coding
