Verifying email and phone number in your mobile app using our iOS SDK consists of the following steps:
Import Cotter
Call Cotter's Login function
Receive user's email or phone number, and whether or not it's verified
We use Cocoapods as our SDK host. If you're using Cocoapods, add this to your Podfile
Then simply run pod install
You will have to do import Cotter on the file that will use Cotter. Then do initialization as follows
