UI WebView and WK WebView Navigation

Question

In my app, I am opening a URL using WK WebView. URL loads correctly, but if I click on some external links in the loaded URL it does not redirect to other websites.

For example

Following is my URL https://www.urlaubstracker.de

In the above link, different holiday deals are linked to external websites. If I click on any button which redirects user to another website, app does not work or load the URL.

I tried using UI WebView and it is working perfectly fine. Could some one please point out what exactly I am missing here in my WK WebView.

Http is not a issue here, as in my app in info.plist I have already did "App Transport Security Settings - Allows Arbitrary Loads to YES". — Waleed Asif, Jun 29 '17 at 10:58
Add NSExceptionAllowsInsecureHTTPLoads = YES may be it will help you.check my answer https://stackoverflow.com/a/44795602/3937664 — Dharma, Jun 29 '17 at 11:10

First, enable ATS in your app.

Now, please try with this code.

var webView: WKWebView?

override func viewDidLoad() {
    super.viewDidLoad()

    let webViewConfiguration = WKWebViewConfiguration()
    webView = WKWebView(frame: view.bounds, configuration: webViewConfiguration)
    let url = URL(string: "https://www.urlaubstracker.de")
    let req = NSURLRequest(url: url!)
    self.webView!.load(req as URLRequest)
    self.webView?.navigationDelegate = self
    webView?.navigationDelegate = self
    webView?.allowsBackForwardNavigationGestures = true
    webView?.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    view.addSubview(webView!)
}

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, 
decisionHandler: (@escaping (WKNavigationActionPolicy) -> Void)) {
print("webView:\(webView) decidePolicyForNavigationAction:\(navigationAction) decisionHandler:\(decisionHandler)")


    switch navigationAction.navigationType {
    case .linkActivated:
        if navigationAction.targetFrame == nil {
            webView.load(navigationAction.request)
        }
    default:
        break
    }

    decisionHandler(.allow)
}

@Waleed Asif, I had tried like this and it is working fine. – rohit chauhan Jun 29 '17 at 11:09
I used exactly your code, but its not working. It loads the URL correctly but whenever I click on the link which should open another website, nothing happens and thats my issue. Using UI Webview its working fine bt not with WK web view that I would like to use as it is recommended by Apple. Could you please help here – Waleed Asif Jun 29 '17 at 12:19
Could you please help me to replicate the same? I have loaded your website with Webkit. Now, where should I click? – rohit chauhan Jun 29 '17 at 12:30
For example in this URL,https://www.urlaubstracker.de/italien-kalabrien-residence-san-leo/ If you try to click on "flug", Wk Webview does not open it (clicking "flug" user is taken on a other website if I use UI Webview). – Waleed Asif Jun 29 '17 at 12:49
@waleed Asif, I have updated my answer please look up to this. – rohit chauhan Jul 04 '17 at 11:16
