The code below shows how to create a UISwitch programmatically with various colors.

Modify ViewController.swift as:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        

        let mySwitch = UISwitch()

        mySwitch.center = view.center

        mySwitch.setOn(false, animated: false)

        mySwitch.tintColor = UIColor.blue

        mySwitch.onTintColor = UIColor.cyan

        mySwitch.thumbTintColor = UIColor.red

        mySwitch.backgroundColor = UIColor.yellow

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

        view.addSubview(mySwitch)

    }

    

    func switchChanged(sender: UISwitch!) {

        print("Switch value is \(sender.isOn)")

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

}

class ViewController: UIViewController {

    override func viewDidLoad() {

        mySwitch.tintColor = UIColor.blueColor()

        mySwitch.onTintColor = UIColor.cyanColor()

        mySwitch.thumbTintColor = UIColor.redColor()

        mySwitch.backgroundColor = UIColor.yellowColor()

        mySwitch.addTarget(self, action: #selector(switchChanged(_:)), forControlEvents: UIControlEvents.ValueChanged)

        view.addSubview(mySwitch)

    }

    

    func switchChanged(sender: UISwitch!) {

        print("Switch value is \(sender.on)")

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

}

Result:
