Example app I created for a eCommerce Meetup Jun 13, 2018.
This demo app was done on version 2 of Moltin. They are now on version 3. The syntax is somewhat the same. I would suggest using Moltin version 3 to get the lastest version. They have an example app that you can also use. It has iOS, TvOS and Apple watch.
The first thing you want to do is go to Moltin and sign up to get your client_id and public_key. Git clone the project and add a Keys.plist file to you project and insert your Client_ID keys.
