Resize UISwitch in Swift 4

问题

I would like to change the default size of the UISwitch in Swift 4.

I have looked at various options but they all relate to v3 and do not work.

Please can someone suggest an example that does so programmatically in Swift 4?

Thank you,

Edit:

I have tried the following examples:

 switchTest.transform = CGAffineTransformMakeScale(0.75, 0.75)

 switchTest.transform = CGAffineTransform(scaleX: 0.75, y: 0.75)

 UISwitch *switchTest = [UISwitch new];
 switchTest.transform = CGAffineTransformMakeScale(0.75, 0.75);

The error message that I received is always the same and says this:

Expected declaration

Swift 4 Code

Method 1

Drag UISwitch Storyboard. Make an outlet of your UISwitch and replace ViewDidLoad method by this code.

@IBOutlet weak var switchDemo: UISwitch!

override func viewDidLoad() {
    super.viewDidLoad()
   switchDemo.transform = CGAffineTransform(scaleX: 0.75, y: 0.75)
}

Method 2

Make UISwitch through programmatically.

class ViewController: UIViewController {

    let switchSwift4 = UISwitch(frame:CGRect(x: 150, y: 300, width: 0, height: 0))

    override func viewDidLoad() {
        super.viewDidLoad()

        self.switchSwift4.isOn = true
        switchSwift4.setOn(true, animated: false)
        switchSwift4.addTarget(self, action: #selector(switchValueDidChange(_:)), for: .valueChanged)
        switchSwift4.transform = CGAffineTransform(scaleX: 0.75, y: 0.75)
        self.view!.addSubview(switchSwift4)
    }

    @objc func switchValueDidChange(_ sender: UISwitch) {
        if switchSwift4.isOn == true {
            print("On")
        }
        else {
            print("Off")
        }
    }
}
