In this video we’re going to set up a Vapor app to handle Sign in with Apple from an iOS device. Let’s get started!

Adding JWT

First open TILApp in the starter project for this course in Xcode and open Package.swift. In the packages dependencies array, add a new dependency for Vapor’s JWT library:

.package(url: "https://github.com/vapor/jwt.git", from: "4.0.0"),
