A demo app using the Siri API to accept payments. This app fakes all of its actual payment interactions, and does not handle real currency.
The Payments app consists of a basic app skeleton (single view controller and
almost no logic or UI), which is only used to request Siri access from the user.
Upon launching the app, ViewController will ask the user for access. It
doesn't handle declined permissions, since that isn't important here.
This is the interesting part of the demo. The Intents extension is registered
with Siri to accept payments. It takes a fake contact book from PaymentsCore
and uses that data to determine whether payments should be allowed.
This UI is just a placeholder for now. It doesn't use any of the information provided by Siri, and instead displays a hardcoded string in a view controller. I'll update this to display user data and a nicer interface later.
