Announcing Swift Apprentice, Seventh Edition!

Are you a Swift beginner wondering how to become a Swift expert?

Do you ever wonder, “What’s the best resource to get me from where I am now to where I want to be in my Swift journey?”

Well, the wait for that resource is over, and the time has come for you to go from being a Swift beginner to blossoming into a Swift expert.

Knock, Knock. Swift Apprentice Is At The Door.

Our Swift Apprentice book is here to teach you all about core Swift language concepts, such as classes, protocols, generics and more!

This book is a companion book to the UIKit Apprentice. UIKit Apprentice focuses on building apps, while Swift Apprentice focuses on the Swift language itself. So you’ll become a Swift language pro, without getting bogged down in the details of building iOS apps.

Who Is This Book For?

If you’re a complete beginner to Swift and wish to dive deep into the language, this book is for you.

What’s Inside the Book?

The newly-updated edition of Swift Apprentice kicks off with the basics of Swift.

Section I: Swift Basics

The chapters in this section will introduce you to the very basics of programming in Swift. You’ll learn about:

• Expressions, Variables & Constants
• Types & Operations
• Basic Control Flow
• Advanced Control Flow
• Functions
• Optionals

Here’s a sneak peek at Playgrounds in Xcode, something which you’ll use to practice your Swift skills in this section, and the rest of the book:

Section II: Collection Types

In this section, you’ll learn about collection types in Swift. Collections are flexible “containers” that let you store any number of values together.

You’ll learn about the following types of collections:

• Arrays, Dictionaries & Sets
• Collection Iteration With Closures
• Strings

Here’s a sneak peek at how Arrays are structured:

Section III: Building Your Own Types

With Swift, you can create your own type by combining variables and functions into a new type definition. When you create a new type, you give it a name; thus, these custom types are known as named types.

Here’s what you’ll learn in this section:

• Structures
• Properties
• Methods
• Classes
• Enumerations
• Protocols
• Generics

Here’s a sneak peek at how to write a class in Swift:

Section IV: Advanced Topics

In this final section of the book, you’ll learn about:

• Access Control, Code Organization & Testing
• Custom Operators, Subscripts & Keypaths
• Result Builders
• Pattern Matching
• Memory Management
• Error Handling

And more! Here’s a sneak peek at NSAttributedString, which is a special object that holds a string and lets you add attributes, like color and font, to the whole string or only to part of it:

What Do You Need?

To follow along with this book, you’ll need the following:

• A Mac running macOS Big Sur 11.6 or later, with the latest point release and security patches installed. This is so you can install the latest version of the required development tool: Xcode.
• Xcode 13 or later. Xcode is the main development tool for writing code in Swift. You need Xcode 13 at a minimum, since that version includes Swift 5.5 Xcode playgrounds. You can download the latest version of Xcode for free from the Mac App Store, here: apple.co/1FLn51R.
