在新的UIWebView中打开链接？

import UIKit

class ViewController: UIViewController, UIWebViewDelegate {

    var webView: UIWebView?

    override func viewDidLoad() {
        super.viewDidLoad()

        let url = URL(string: "https://www.example.com")!
        webView = UIWebView(frame: view.bounds)
        webView?.delegate = self
        webView?.loadRequest(URLRequest(url: url))
        view.addSubview(webView!)
    }

    func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
        if navigationType == .linkClicked {
            let safariViewController = SFSafariViewController(url: request.url!)
            present(safariViewController, animated: true, completion: nil)
            return false
        }
        return true
    }
}
