如何访问iOS项目中的浏览器历史记录？

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建WKWebView实例
        webView = WKWebView(frame: view.bounds)
        webView.navigationDelegate = self
        view.addSubview(webView)
        
        // 加载网页
        let url = URL(string: "https://www.example.com")
        let request = URLRequest(url: url!)
        webView.load(request)
        
        // 获取浏览器历史记录
        if let backForwardList = webView.backForwardList {
            let backList = backForwardList.backList
            let forwardList = backForwardList.forwardList
            
            // 遍历过去的页面列表
            for item in backList {
                let url = item.url
                let title = item.title
                // 处理每个页面的URL和标题
            }
            
            // 遍历将来的页面列表
            for item in forwardList {
                let url = item.url
                let title = item.title
                // 处理每个页面的URL和标题
            }
        }
    }
    
    // WKNavigationDelegate方法
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        // 网页加载完成后的处理
    }
}
