Swift/UISwitch: how to implement a delegate/listener

Question

In my UITableViewController I have a custom cell which contains a switcher which is the following:

import Foundation
import UIKit

class SwitchCell: UITableV         


        

Answer 1

In Swift4.0

mySwitch.addTarget(self, action: #selector(valueChange), for:UIControlEvents.valueChanged)

 @objc func valueChange(mySwitch: UISwitch) {
        let value = mySwitch.isOn
        // Do something
        print("switch value changed \(value)")
    }
