Swift Cookbook. - Second Edition

By: Keith Moon, Chris Barker

Overview of this book

Swift is an exciting, multi-platform, general-purpose programming language, and with this book, you'll explore the features of its latest version, Swift 5.3. The book begins with an introduction to the basic building blocks of Swift 5.3, its syntax, and the functionalities of Swift constructs. You’ll then discover how Swift Playgrounds provide an ideal platform to write, execute, and debug your Swift code. As you advance through the chapters, the book will show you how to bundle variables into tuples or sets, order your data with an array, store key-value pairs with dictionaries, and use property observers. You’ll also get to grips with the decision-making and control structures in Swift, examine advanced features such as generics and operators, and explore functionalities outside of the standard library. Once you’ve learned how to build iOS applications using UIKit, you'll find out how to use Swift for server-side programming, run Swift on Linux, and investigate Vapor. Finally, you'll discover some of the newest features of Swift 5.3 using SwiftUI and Combine to build adaptive and reactive applications, and find out how to use Swift to build and integrate machine learning models along with Apple’s Vision Framework. By the end of this Swift book, you'll have discovered solutions to boost your productivity while developing code using Swift 5.3.

Mastering the Building Blocks

The previous chapter explained the basic types that form the building blocks of the Swift language. In this chapter, we will build on this knowledge to create more complex structures, such as arrays and dictionaries, before moving on and looking at some of the little gems Swift offers, such as tuples and typealias. Finally, we'll round off this chapter by looking at extensions and access control – both of which are key components that contribute to a sound yet efficient codebase.

In this chapter, we will cover the following recipes:

  • Bundling variables into tuples
  • Ordering your data with arrays
  • Containing your data in sets
  • Storing key-value pairs with dictionaries
  • Subscripts for custom types
  • Changing your name with typealias
  • Getting property changing notifications using property observers
  • Extending functionality with extensions
  • Controlling access with access control

Let's get started!
