import SafariServices

class ViewController: UIViewController, SFSafariViewControllerDelegate {
    // ...
    
    func openSafariViewController() {
        let url = URL(string: "https://example.com")!
        let safariViewController = SFSafariViewController(url: url)
        safariViewController.delegate = self
        present(safariViewController, animated: true, completion: nil)
    }
    
    func safariViewControllerDidFinish(_ controller: SFSafariViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
}

import SafariServices

class ViewController: UIViewController {
    // ...
    
    func openSafariViewController() {
        let url = URL(string: "https://example.com")!
        let safariViewController = SFSafariViewController(url: url)
        NotificationCenter.default.addObserver(self, selector: #selector(dismissSafariViewController), name: NSNotification.Name.SFSafariViewControllerDidFinish, object: safariViewController)
        present(safariViewController, animated: true, completion: nil)
    }
    
    @objc func dismissSafariViewController() {
        NotificationCenter.default.removeObserver(self, name: NSNotification.Name.SFSafariViewControllerDidFinish, object: nil)
        dismiss(animated: true, completion: nil)
    }
}
