Welcome to another course from DevTechie. In this video course we will build complete app from scratch. We will build this app in SwiftUI 3 and iOS 15. This will be an e-commerce app where we will sell shoes to our customers. You will learn to not only build apps in SwiftUI with this course but you will also learn how to integrate Apple Pay for goods purchase.

We will start by building out interface for our app, where user can list all the products, see details about the product and add them to the cart. Cart manager will be responsible to manage cart at the app level and will make it possible to add items to cart from any where in the app. We will also build Cart manager in such a way where it can handle duplicate products and combine them together to build cart with quantity.

You will learn to create merchant ids for Apple Pay so your users can purchase products from your app without you having to build pipeline for payment processing. Apple Pay provides way to directly integrate payment processing engine in the form of PassKit framework and you will learn to use that so you can use user's wallet data to payment processing without owning or saving any information inside you app.

There is a lot that needs to be done to build an e-commerce app and Apple Pay makes it easy with just few simple steps and those are the steps we will learn in this video course. So join me in this course and build this awesome app together.
