Swift Version

// Add observer
webView.addObserver(self, forKeyPath: "URL", options: .new, context: nil)

// Observe value
override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
    if let key = change?[NSKeyValueChangeKey.newKey] {
        print("observeValue \(key)") // url value
    }
}
