将UIWebView迁移到WKWebView

Question

Within my iOS app I am attempting to migrate my old UIWebView code to WKWebView since WKWebView is, in theory, faster and more efficient than UIWebView.

I have looked at a bunch of tutorials (like here and here and here ) on the internet but cant find anything that explains how to simply add a WKWebView to my app progmatically.

Can someone point me to a simple tutorial or explain in the comments how to convert this code to WKWebView progmatically? thanks in advance.

View Controller.swift:

import UIKit

class ViewController: UIViewController, UIWebViewDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        let myWebView:UIWebView = UIWebView(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height))

        myWebView.loadRequest(NSURLRequest(URL: NSURL(string: "http://www.communionchapelefca.org/app-home")!))
        self.view.addSubview(myWebView)

Add " WebKit " framework to your class.

Please refer the below code

import UIKit
import WebKit

class ViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let myWebView:WKWebView = WKWebView(frame: CGRectMake(0, 0,   UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height))

        myWebView.loadRequest(NSURLRequest(URL: NSURL(string: "http://www.communionchapelefca.org/app-home")!))
        self.view.addSubview(myWebView)

    }
}
