How do I make a custom UISegmentedControl?

This is how I managed it. Make a segmented control and insert segments using the images. Be sure to set one image as selected as this will be the initial selected index. Also set the backgroundColor and tintColor to clear so that segmented control will only show your image.

var newSegmentedControl: UISegmentedControl = {
        let segmentedControl = UISegmentedControl()

        segmentedControl.insertSegment(with: UIImage(named: "x_Selected.jpg"), at: 0, animated: true)
        segmentedControl.insertSegment(with: UIImage(named: "y_Normal.jpg"), at: 1, animated: true)

        segmentedControl.addTarget(self, action: #selector(segmentedControlChanged), for: .valueChanged)

        segmentedControl.selectedSegmentIndex = 0
        segmentedControl.backgroundColor = .clear
        segmentedControl.tintColor = .clear            

    }()

Function called when the value of segmented control changes.

@objc func segmentedControlChanged(sender: UISegmentedControl) {

    if sender.selectedSegmentIndex == 0 {
        sender.setImage(UIImage(named: "x_Selected.jpg"), forSegmentAt: sender.selectedSegmentIndex)
        sender.setImage(UIImage(named: "y_Normal.jpg"), forSegmentAt: 1)
    } else if sender.selectedSegmentIndex == 1 {
        sender.setImage(UIImage(named: "x_Normal.jpg"), forSegmentAt: 0)
        sender.setImage(UIImage(named: "y_Selected.jpg"), forSegmentAt: sender.selectedSegmentIndex)
    } 

}
