Help Integrate iOS App for Square Card Reader SDK (credit card reader)

Hi. I would love to find someone with experience with the Square API - ie squareup.com I want to first get a working version of their sample app for the Square Credit Card Reader SDK, which allows you to take a credit card with their card reader but on an iOS App you can control.

Then if that goes well, I'll have you help me integrate this as a payment option into an iOS App that I already have that's mostly made with Swift.

Here's a sample project on Github that I would like installed in an iOS XCode file so I can run it and test it first.

Thanks!
