How to fetch all Google Contacts in iOS 10
<p>I have tried to get all google contacts using Google Contacts APi but I didnt find anything working for iOS. OAuth is not working because google changed Policies for Using WebView OAuth. I get access-token using Google Sign In Framework but this token is invalid with google contacts API:
