I've updated the Stripe SDK to the latest version 21.0.1 via CocoaPods.
When I'm building the project I'm always getting the following error:
No such module 'Stripe3DS2'
in the STP3DS2AuthenticateResponse.swift
file.
Okay, I just fixed it by updating CocoaPods itself from 1.9 to 1.10
sudo gem install cocoapods
