Fondamentaux de la programmation iOS 15 avec Swift

Introduction

The book «iOS 15 Programming Fundamentals with Swift» (author — Matt Neuburg, 2021, 806 pages) is not just another guide to Swift.

Each new version of iOS is accompanied by an update to this series, and iOS 15 is no exception. In this review, we will break down why this book is useful for beginners and experienced programmers, what topics it covers, and why it is worth reading for anyone who wants to deeply understand the Apple platform.

Part II: Tools — Xcode 13

The second part is dedicated to the Xcode 13 development environment, Interface
