Otafuku provides utility classes to use WKWebView.

Features

WebViewUIController to handle WKUIDelegate methods by presenting an alert as usual browsers do.
WebViewPropertyObserver to notify WKWebView property value change via a registered closure and Swift enum. With this class, no KVO code is needed to know WKWebView property value change.

Usage

WebViewUiController

WebViewUIController handles WKUIDelegate.
As shown below, simply declare a property of WebViewUIController and set it to WKWebView.UIDelegate in UIViewController.viewDidLoad.


                                              
                                                class ViewController: UIViewController {

let uiDelegate = WebViewUIController()
override func viewDidLoad() {

super.viewDidLoad()

webView.UIDelegate = uiDelegate

}

}

WebViewPropertyObserver

WebViewPropertyObserver notifies WKWebView property value change.
As shown below, declare a property of WebViewPropertyObserver to retain its object throughout the ViewController’s life cycle.
To initialize, pass a WKWebView object and a closure handling WKWebView’s property change.


                                              
                                                class ViewController: UIViewController {

@IBOutlet var progressView: UIProgressView!

@IBOutlet var backItem: UIBarButtonItem!

@IBOutlet var forwardItem: UIBarButtonItem!
var propertyObserver: WebViewPropertyObserver?
override func viewDidLoad() {

super.viewDidLoad()

propertyObserver = WebViewPropertyObserver(webView: webView, handler:handleWebViewPropertyChange)

}
func handleWebViewPropertyChange(property: WebViewPropertyObserver.WebViewProperty) {

switch property {

case .Title(let title):

navigationItem.title = title

case .URL(let URL):

// do something with URL

break

case .CanGoBack(let canGoBack):

backItem.enabled = canGoBack

case .CanGoForward(let canGoForward):

forwardItem.enabled = canGoForward

case .EstimatedProgress(let progress):

progressView.progress = progress

case .Loading(let loading):

// do something with loading

break

case .HasOnlySecureContent(let secureContent):

// do something with secureContent

break

}

}

}
