iOS E-Commerce App, Swift - Help add page(s) from a Sample App to My App

Hi there. I want to add the 2 credit card pages from the attached Sample App (made by the famous payments company Square) to my iOS app (basically I have to replace the Old Credit Card form with their New Credit Card Form). Their new credit card form (in this sample app) basically generates a payment (ie. credit card nonce/token), so that Customers can pay for purchases with a secure credit card. This sample app is super easy. It took me 5 minutes to setup and it easily generates a nonce that displays in the XCode Console and I also found the code that actually turns the nonce into a variable (so we can pass it easily to an API call). So, once we add the necessary code, controllers, etc from the Sample App to MY App, then I need help getting my payment process to work with it (since I'm basically updating my credit card form). I think all we would have to do is pass the nonce/token to a Payments API Call (along with the OrderID that my App already generates and passes to the old credit card form). Note: The Sample App actually has a CURL example that posts to the Payments API. So, I think there are probably 2 easy ways to get Orders working with this new Credit Card Form. 1) Either we can pass the Order ID from my existing process along with the Nonce/Token from this new Credit Card form to the CURL Payments API. Or, 2) We can pass the Order ID from my existing process along with the Nonce/Token from this new Credit Card form to one of my existing API Calls, which all sort of look like this: [login to view URL](url, method: .post, parameters: params).responseJSON { [weak self] response in We have to do this via AnyDesk or Screenshare because a) I can't share the source and b) it would take way too long getting it all to work on your system anyway. Thanks!
