Swift_Apprentice_Basics_Introduction

The chapters in this section will introduce you to the very basics of programming in Swift. From the fundamentals of how computers work all the way up to language structures, you’ll cover enough of the language to be able to work with data and organize your code’s behavior. The section begins with some groundwork to get you started:

• Chapter 1, Coding Essentials & Playground Basics: This is your whirlwind introduction to the world of programming! You’ll begin with an overview of computers and programming, and then say hello to Swift playgrounds, where you’ll spend your coding time for the rest of this book.

• Chapter 2, Expressions, Variables & Constants: You’ll start by learning some basics such as code comments, arithmetic operations, constants, and variables. These are fundamental building blocks of any language, and Swift is no different.

• Chapter 3, Types & Operations: You’ll learn about handling different types, including strings which allow you to represent text. You’ll learn about converting between types, and you’ll also be introduced to type inference which simplifies programming. Additionally, you’ll explore tuples, which allow you to create your own types made up of multiple values of any type.

• Chapter 4, Basic Control Flow: You’ll learn how to make decisions and repeat tasks in your programs using syntax to control the flow. You’ll also learn about Booleans.
