How to implement a swipeable stack of cards in SwiftUI

Every now and then, an app solves a common problem in such an elegant and peculiar way that it becomes a sort of de facto way to do it in other apps as well.

I am referring to a pattern such as pull to refresh, which started in the Twitter app and then became part of iOS itself.

A few years ago, Tinder introduced the pattern of swipeable cards to solve the problem of indicating in a list of cards which cards we like and which we dislike.

From then on, countless apps have applied the same visual pattern, not just in the dating sector but in every sector that needed a way to make a match between different users, including anything from business purposes, such as coupling mentors and mentees, to indicating which clothes we like for a fashion e-commerce app.

In this recipe, we are going to implement a barebones version of Tinder's swipeable stack of cards.
