WKWebView not loading webpage - renders blank screen in Swift

Question

This code is supposed to load the Apple homepage, but instead shows a blank screen.
This happens with both HTTP and HTTPS URLs.

Code:

import UIK         


        

Answer 1

The correct way with auto layout and constant 10 for all device:

import UIKit
import WebKit

class ViewController: UIViewController, WKUIDelegate {

let webView = WKWebView()

override func viewDidLoad() {
    super.viewDidLoad()
    setupWebView()
}

fileprivate func setupWebView() {
    webView.uiDelegate = self
    webView.translatesAutoresizingMaskIntoConstraints = false
    DispatchQueue.main.async {
        guard let url = URL(string: "http://www.apple.com") else { return }
        self.webView.load(URLRequest(url: url))
    }
    view.addSubview(webView)
    webView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 10).isActive = true
    webView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor, constant: 10).isActive = true
    webView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -10).isActive = true
    webView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: 10).isActive = true
}}
