how do implement action on switch with Material (CosmicMind)

Question

i'm trying to add a switch in my app. I added it in the storyboard (IUView with Switch class and Material module. I customed it in my viewcontroller but I don't know how to do the action on it.

I tried adding IBAction with the touch up inside event, but I have nothing when I touch it.

Thanks.

My code:

import Foundation
import UIKit 
import Material

class SettingsVC: UIViewController {

    @IBOutlet weak var addCalendarSwitch: Switch!

    override func viewDidLoad() {
        super.viewDidLoad()

        addCalendarSwitch.delegate = self
        addObserver()
        setStyle()
        setView()
        getStatusAddCalendar()
    }

    func getStatusAddCalendar(){
        if UserDefaults.standard.bool(forKey: "addToCalendar") == true 
        {
            addCalendarSwitch.isOn = true
        }
        else {
            addCalendarSwitch.isOn = false
        }
    }
}

extension ViewController: SwitchDelegate {

    // utilise the delegate method
    func switchDidChangeState(control: Switch, state: SwitchState) {
        print("Switch changed state to: ", .on == state ? "on" : "off")
    }
}

Looking at the examples it seems it is using a delegate pattern. https://github.com/CosmicMind/Samples/blob/master/Projects/Programmatic/Switch/Switch/ViewController.swift

import UIKit
import Material

class ViewController: UIViewController {

    // create an outlet and connect it from your storyboard
    @IBOutlet weak var mySwitch: Switch!

    override func viewDidLoad() {
        super.viewDidLoad()
        // use this outlet to assign the delegate
        mySwitch.delegate = self
    }
}

// conform to the protocol
extension ViewController: SwitchDelegate {

    // utilise the delegate method
    func switchDidChangeState(control: Switch, state: SwitchState) {
        print("Switch changed state to: ", .on == state ? "on" : "off")
    }
}
