Answer 1

You only need to change, the UIWebView for WKWebView add import WebKit and change the class name for your Outlet to WKWebView, also change the loadRequest for load

import UIKit
import WebKit



class ViewController: UIViewController {

 @IBOutlet weak var webView: WKWebView!

      let urlString: String = "https://google.com"

     override func viewDidLoad() {
         super.viewDidLoad()
         guard let url =  URL(string: urlString) else { return }
         let requestObj = URLRequest(url: url)
         webView.load(requestObj)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

The new API will be the same

wkWebView.load(URLRequest(url: url))
