how to login with google+ in iOS

do we have any documentation on login with google+ ??

please check this example

hey @sergey thanks for responding but i was asking about how to get the Google Plus ID and secret key ??

i tried on my own but am not sure where to find this id’s in google developer console and also this message is making things more complicated Google+ Sign-In is deprecated, and is likely to not function as expected. Do not use Google+ Sign-In in new apps. To sign in users with their Google Accounts, use Google Sign-In. See the migration guide to migrate from Google+ Sign-In.
