title: iOS13 check for internet connection instantly
body: <p><br>
  I state that I am new to Swift and iOS in general.<br>
  I'd like to understand (in viewDidLoad) how I can check if the iPhone is connected to the internet, instantly, at that moment!<br>
  The new NWPathMonitor() class seems to be useful only for managing connection changes, but not for instantaneously checking the connection.<br></p>
  
  <p>My ViewController</p>
  
  <pre><code>import UIKit
  import WebKit
  import Network
  
  class ViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {
  
      // Status bar black characters
      override var preferredStatusBarStyle: UIStatusBarStyle { return .darkContent }
      // La nostra webview
      var webView: WKWebView!
      // NETWORK MONITORING
      let monitor = NWPathMonitor()
      let queue = DispatchQueue(label: "InternetConnectionMonitor")
      var internetConnected = false
  
      // 1 - Eseguita durante il caricamento della view
      override func loadView() {
          super.loadView()
  
          // WEB VIEW
          let webConfiguration = WKWebViewConfiguration()
          webView = WKWebView(frame: .zero, configuration: webConfiguration)
          webView.uiDelegate = self
          view = webView
  
          // NETWORK MONITORING
          monitor.pathUpdateHandler = { path in
              if path.status == .satisfied {
                  print("dedalos-print INTERNET OK 1")
                  if (!self.internetConnected) {
                      self.internetConnected = true
                      self.loadWebView()
                  }
              }
              else {
                  print("dedalos-print NO INTERNET 1")
                  self.internetConnected = false
                  self.loadHTMLerror()
              }
          }
  
          monitor.start(queue: queue)
  
      }
  
      // 2 - Eseguita dopo il caricamento della view
      override func viewDidLoad() {
          super.viewDidLoad()
  
          if (self.internetConnected) {
              print("dedalos-print INTERNET OK 2")
              self.loadWebView()
          }
          else {
              print("dedalos-print NO INTERNET 2")
          }
  
      }
  
      // 3 - Eseguita poco prima di mostrarsi
      override func viewWillAppear(_ animated: Bool) {
          super.viewWillAppear(animated)
      }
  
      // 4 - Eseguita dopo essersi mostrata
      override func viewDidAppear(_ animated: Bool) {
          super.viewDidAppear(animated)
      }
  
      override func viewWillDisappear(_ animated: Bool) {
          super.viewWillDisappear(animated)
      }
  
  
  }

  <p>Thanks in advance!</p>
