let uiDelegate = WebViewUIController()
override func viewDidLoad() {
super.viewDidLoad()
webView.UIDelegate = uiDelegate
}
}

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):
