SelectedTintColor of Segment Control is not rounded corner on iOS 13

Question

Rounded corner is working great on iOS 12 and below, but it\'s broken on iOS 13. I\'ve created a custom Segment control class.

If you use a subclass:

override func layoutSubviews() {
    super.layoutSubviews()
    roundCorners(radius: frame.height / 2)

    if #available(iOS 13.0, *) {
        selectedSegmentTintColor = .clear
    } else {
        tintColor = .clear
    }

    for (index, subview) in subviews.enumerated() {
        if ((subviews[index] as? UIImageView) != nil) && index == selectedSegmentIndex {
            subview.backgroundColor = .white
            subview.roundCorners(radius: subview.frame.height / 2)
        } else {
            subview.backgroundColor = .clear
        }
    }
}

private func roundCorners(radius: CGFloat) {
    layer.roundCorners(radius: radius)
    self.clipsToBounds = true
}

If you use the default segmented control, you just prefix with name of your segmented control:

mySegmentedControl.selectedSegmentTintColor = .clear

for (index, subview) in mySegmentedControl.subviews.enumerated() {
   .....
}
