I would like to allow the user to authenticate with google, etc but it seems the docs are missing for IOS. Are there any relevant tutorials that one can point me to using KinveyKit on iOS? I've searched and while there are a couple of threads on Google+ signin, they dont seem to be relevant anymore.
Thanks for writing this to us.
I will convey the issue about "Login using Google+" to engineering team and will get back to you once I have more information on it.
