Capture redirect url in wkwebview in ios

Use this WKNavigationDelegate method

public func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Swift.Void) {
        if(navigationAction.navigationType == .other) {
            if let redirectedUrl = navigationAction.request.url {
                //do what you need with url
                //self.delegate?.openURL(url: redirectedUrl)
            }
            decisionHandler(.cancel)
            return
        }
        decisionHandler(.allow)
    }

WKWebView - Add a parameter to the URL on redirect in Swift - iOS

WKNavigationDelegate, URLComponents

class ViewerViewController: UIViewController, WKNavigationDelegate  //<--
// then whenever you call the WKWebView
//ex: URL = https://en.wikipedia.org/wiki/Main_Page

WKWebView.navigationDelegate = self


WKWebView.load(URLRequest)


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




    print("URL:", navigationAction.request.url)
    if let host = navigationAction.request.url?.path 
     {
         if host.contains("Main_Page")
          {
              //You can modify this part to form a new url and pass it again.
              var components = URLComponents()
              components.scheme = navigationAction.request.url?.scheme
              components.host =  navigationAction.request.url?.host
              components.path =  navigationAction.request.url!.path 
                        
             print("new URL:", components.url!)
             let customRequest = URLRequest(url: components.url!)

             //change the url and pass it again..
             WKWebView.load(customRequest) //<--load the new url again..
             decisionHandler(.cancel) 
        }
        else
        {
             decisionHandler(.allow) //<-- this will open the page.
        }
     }
     else
     {
         decisionHandler(.allow)
     }
}

Problem loading a URL in WKWebView that works fine on SFSafariViewController

The difference is caused by the User-Agent header being different when loading via a WKWebView vs SFSafariViewController. The website you are loading must be using the User-Agent header to determine where to redirect.

By setting the customUserAgent property on your WKWebView to the default iOS Safari User-Agent the same page will be directed to in your WKWebView as when using SFSafariViewController:

webView.customUserAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 15_5 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.5 Mobile/15E148 Safari/604.1"
