I am trying to open a URL in safari browser while clicking it from app's iOS WKWebView, but when I call window.open() from javascript which has no effects.
It's not hitting the decide policy in WKWebView,
[Foundation.Export("webViewecidePolicyForNavigationActionecisionHandler:")]
public void DecidePolicy(WKWebView webView, WKNavigationAction navigationAction, Action decisionHandler)
I have tried to override WKUIDelegate method, but it's not working. 
Could anyone help me out?
