Private browsing in iOS using WKWebView

As per apple documentation : To support private browsing,create a data store object and assign it to the websiteDataStore property of a WKWebViewConfiguration object before you create your web view. The default() method returns the default data store that saves website data persistently to disk. To implement private browsing, create a nonpersistent data store using the nonPersistent() method instead.

    let webConfiguration = WKWebViewConfiguration()
    webConfiguration.processPool = WKProcessPool()
    webConfiguration.websiteDataStore = WKWebsiteDataStore.nonPersistent()
    let webView = WKWebView(frame: self.webContainerView.bounds, configuration: webConfiguration)
    // Set up request
    if let requestURL = URL(string: "enter_url_to_load") {
        var request = URLRequest(url: requestURL)
        request.httpShouldHandleCookies = false
        request.cachePolicy = .reloadIgnoringLocalAndRemoteCacheData
        webView.navigationDelegate = self
        webView.load(request)
    }
    self.webContainerView.addSubview(webView)
