是否可以在使用Swift关闭SFSafariViewController时编辑动画？

import UIKit
import SafariServices

class ViewController: UIViewController {
    
    var safariViewController: SFSafariViewController?
    
    @IBAction func openSafariButtonTapped(_ sender: UIButton) {
        let url = URL(string: "https://www.example.com")!
        safariViewController = SFSafariViewController(url: url)
        present(safariViewController!, animated: true, completion: nil)
    }
    
    // 监听SFSafariViewController的关闭事件
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        if let safariViewController = safariViewController, safariViewController.isBeingDismissed {
            // 添加自定义动画效果
            UIView.animate(withDuration: 0.3) {
                // 自定义动画逻辑
                self.view.alpha = 0.5
            } completion: { _ in
                // 动画完成后恢复视图状态
                self.view.alpha = 1.0
            }
        }
    }
}
