Please tell me how to keep the cookie of WKWebbview.
I'm changing Webview from UIWebView to WKWebview.
I can not get session ID (cookie) regenerated by server login authentication and Then I can not log in.
It looks like cookie synchronization does not go well.
So please tell me how to keep the cookie of WK Webbview.

< login authentication>
1.Login authentication with WebAPI
⇒Get PHPSESSID from server
2.Send PHPSESSID with MutableURLRequest
※I set PHPSESSID to WKWebview with WKUserScript
3.Login authentication with server (using cakephp authComponent)
⇒Regenerate session ID and reset to cookie(PHPSESSID)★
★problem
The cookie of the request is not updated at the timing of webView (decidePolicyFor: decisionHandler )
