	import UIKit
	class ViewController: UIViewController {
	private lazy var sampleView: UIView = {
	let view = UIView()
	view.translatesAutoresizingMaskIntoConstraints = false
	view.backgroundColor = .systemCyan
	return view
	}()
	override func viewDidLoad() {
	super.viewDidLoad()
	view.addSubview(sampleView)
	NSLayoutConstraint.activate([
	sampleView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
	sampleView.centerYAnchor.constraint(equalTo: view.centerYAnchor),
	sampleView.widthAnchor.constraint(equalToConstant: 200),
	sampleView.heightAnchor.constraint(equalToConstant: 200),
	])
	setSpecificCornerRadius()
	}
	private func setSpecificCornerRadius() {
	// MARK: top-left & top-right corenrs
	sampleView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
	// // MARK: top-left & bottom-right corners
	// sampleView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMaxYCorner]
	// // MARK: bottom-left & top-right corners
	// sampleView.layer.maskedCorners = [.layerMaxXMinYCorner, .layerMinXMaxYCorner]
	// // MARK: bottom-left & bottom-right corners
	// sampleView.layer.maskedCorners = [.layerMinXMaxYCorner, .layerMaxXMaxYCorner]
	sampleView.layer.cornerRadius = 16
	}
	}
