Swift Essentials

Swift Essentials is a practical, beginner-friendly introduction to Swift programming for Apple platforms.

Starting from the absolute basics, the book builds each concept step by step through clear explanations, solved examples, practice exercises, and complete projects. You will learn how Swift handles variables, constants, types, control flow, functions, optionals, collections, structs, classes, protocols, closures, generics, error handling, memory management, Codable, concurrency, testing, and more.

The examples are designed to be typed, modified, and explored in Xcode Playgrounds, helping you understand not only what the code does, but why it works.
By the end of the book, you will have built several complete command-line projects and developed the foundations needed to continue into SwiftUI, app architecture, and full iPhone, iPad, and Mac development.

No previous programming experience is required.
