Method 1: let config = WKWebViewConfiguration()

    let preferences = WKPreferences()
    preferences.javaScriptCanOpenWindowsAutomatically = false
    config.preferences = preferences
    
    let cookieStore = WKWebsiteDataStore.nonPersistent()
    config.websiteDataStore = cookieStore
    
    webView = WKWebView(frame: view.bounds, configuration: config)
    webView.navigationDelegate = self
    
    if let url = URL(string: "https://emerald-lyssa-85.tiiny.site/") {
        // Create a URLRequest with the URL
        let request = URLRequest(url: url)
        // Load cookies from the request
        if let cookies = HTTPCookieStorage.shared.cookies(for: url) {
            for cookie in cookies {
                webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie, completionHandler: nil)
            }
            // Load the URLRequest in the webView
            webView.load(request)
        }
    }
    view.addSubview(webView)

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {

    guard let response = navigationResponse.response as? HTTPURLResponse,
          let url = navigationResponse.response.url else {
        decisionHandler(.cancel)
        return
    }
    
    if let headerFields = response.allHeaderFields as? [String: String] {
        let cookies = HTTPCookie.cookies(withResponseHeaderFields: headerFields, for: url)
        cookies.forEach { cookie in
            webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)
        }
    }
    decisionHandler(.allow)
}

These methods are am tried its not working

Answer 1

I am not sure if I understood your problem correctly, but..

In general, WKWebView has cookies enabled by default. You can access the store WKWebView.configuration.websiteDataStore.httpCookieStore and play with them using getAllCookies(_:) and setCookie(_:) methods, as you did.

By configuring WKWebsiteDataStore.nonPersistent() in your code snippet I assume, that you do not want to persist WKWebView cookies between consequent app launches. On the other hand, I conclude, you want to transfer the cookies saved previously in Safari to your WKWebView and that is why you try to read them from HTTPCookieStorage.shared.

In HTTPCookieStorage documentation we can read that:

iOS — Each app and app extension has a unique data container, meaning they have separate cookie stores. You can obtain a common cookie storage by using the sharedCookieStorage(forGroupContainerIdentifier:) method.

This means that you cannot read Safari cookies from HTTPCookieStorage.shared.cookies(for:) because it only applies to your sandboxed app and they will not be stored there.

Only SFSafariViewController would be capable of using Safari cookies, but you have no programmatic access there anyway.
