Separate cookie storage for two (UIWebView or WKWebView) - ios

Question

I want to login many accounts of same site in different webView. For example i have Tab Bar Controller that contains three view controllers and each view controllers contain webView. And for example i embed stackoverflow url for webView in every class. How user can login to different accounts at the same time using these three webView? I've tried this but i can just login one user at a time.
I have found that i need to create separate cookie for every UIWebView, but mostly answers are in objective-c and not the proper answer i want. For example (First Second Third)
Can any one please tell me how i can do it?
class FirstViewController: UIViewController , UIWebViewDelegate{
#IBOutlet weak var webView: UIWebView!
#IBOutlet weak var activityIndicator: UIActivityIndicatorView!
override func viewDidLoad() {
webView.delegate = self
let requestURL = NSURL(string: "http://stackoverflow.com")
let request = NSURLRequest(URL: requestURL!)
activityIndicator.hidesWhenStopped = true
activityIndicator.startAnimating()
webView.loadRequest(request)
}
func webViewDidFinishLoad(webView: UIWebView) {
activityIndicator.stopAnimating()
}
}
class SecondViewController: UIViewController, UIWebViewDelegate{
#IBOutlet weak var webView: UIWebView!
#IBOutlet weak var activityIndicator: UIActivityIndicatorView!
override func viewDidLoad() {
webView.delegate = self
let requestURL = NSURL(string: "http://stackoverflow.com")
let request = NSURLRequest(URL: requestURL!)
activityIndicator.hidesWhenStopped = true
activityIndicator.startAnimating()
webView.loadRequest(request)
}
func webViewDidFinishLoad(webView: UIWebView) {
activityIndicator.stopAnimating()
}
}
Thanks

You can do this with WKWebView by using different instances of WKWebSiteDataStore:
let configuration1 = WKWebViewConfiguration()
configuration1.websiteDataStore = WKWebsiteDataStore.nonPersistent()
self.webView1 = WKWebView(frame: CGRect.zero, configuration: configuration1)
self.view.addSubview(self.webView1)
let configuration2 = WKWebViewConfiguration()
configuration2.websiteDataStore = WKWebsiteDataStore.nonPersistent()
self.webView2 = WKWebView(frame: CGRect.zero, configuration: configuration2)
Unfortunately, you will loose webView data (such as cookies, cache, etc) after app restart, because non-persistent WKWebsiteDataStore can't be saved to disk (you could notice that WKWebsiteDataStore implements NSCoding, but it doesn't work for non-persistent stores).
