Question

I am trying to get my Hybrid IOS app that uses Swift and WKWebviews to open a link that has target=\"_blank\" or if the URL contains http://,

Answer 1

Code updated for iOS 10 Swift 3:

override func loadView() {
    super.loadView()
    self.webView.navigationDelegate = self 
    self.webView.uiDelegate = self  //must have this
}

func webView(_ webView: WKWebView,
               createWebViewWith configuration: WKWebViewConfiguration,
               for navigationAction: WKNavigationAction,
               windowFeatures: WKWindowFeatures) -> WKWebView? {
    if navigationAction.targetFrame == nil, let url = navigationAction.request.url {
      if url.description.lowercased().range(of: "http://") != nil ||
        url.description.lowercased().range(of: "https://") != nil ||
        url.description.lowercased().range(of: "mailto:") != nil {
        UIApplication.shared.openURL(url)
      }
    }
  return nil
}
