根据 claude31 提供的链接，您可以执行以下操作:

    private let containerView: UIView = {
        let view = UIView()
        view.translatesAutoresizingMaskIntoConstraints = false
        
        view.clipsToBounds = true
        view.layer.cornerRadius = 28
        view.layer.maskedCorners = [.layerMaxXMinYCorner, .layerMinXMinYCorner]//Define the corners you want to round here.
        
        view.backgroundColor = .systemBlue
        return view
    }()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        configureUI()
    }
    
    private func configureUI() {
        view.addSubview(containerView)
        
        NSLayoutConstraint.activate([
            containerView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            containerView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            containerView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            containerView.topAnchor.constraint(equalTo: view.topAnchor, constant: 270)
        ])
    }

结果看起来像这样:
