Rounded corners of the view and its selectedSegment

1. **Create a custom subclass of UISegmentedControl:**
final class SegmentedControl: UISegmentedControl {
private var cornerRadius: CGFloat
init(cornerRadius: CGFloat) {
self.cornerRadius = cornerRadius
super.init(frame: .zero)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func layoutSubviews() {
super.layoutSubviews()
layer.cornerRadius = cornerRadius
guard let selectedSegment = subviews[numberOfSegments] as? UIImageView else {
return
}
selectedSegment.image = nil
selectedSegment.backgroundColor = selectedSegmentTintColor
selectedSegment.layer.removeAnimation(forKey: "SelectionBounds")
selectedSegment.layer.cornerRadius = cornerRadius - layer.borderWidth
selectedSegment.bounds = CGRect(origin: .zero, size: CGSize(
width: selectedSegment.bounds.width,
height: bounds.height - layer.borderWidth * 2
))
}
}
2. **Create an instance of SegmentedControl and don't forget to set `selectedSegmentTintColor`**
