Do I have to compile using Swift when using Auth0 with React Native?

I’m using Auth0 with React Native, and came across this documentation: ( on Auth0.swift . It says “Behaviour changes in iOS 13 related to Web Authentication require that developers using Xcode 11 with this library must compile using Swift 5.x”. I’m using iOS 13 and Xcode 11, and am encountering bugs in Auth0.

What I Want To Know:

Does this quote necessarily apply to me? I don’t know anything about Swift, or if it’s already being used in my project. Is Auth0.swift just another library that I may or may not be using? Should I use it? Any insight would be appreciated.
