UIWebView to WKWebView, old ionic v1 to ionic v2+

Hi

Currently, I’m maintaining an old version angularJS 1+ and ionic v1 application.
Now Apple announced to move from UIWebView to WKWebView.

Is there a way to keep my angularJS 1+ codes but move from UIWebView to WKWebView?
Is there a way to use angularJS 1+ codes in ionic v2+ framework?

thanks a lot
