Preface
In December 2015, Apple released Swift as an open source project on its GitHub page. With this release, Apple also released a version of Swift for Linux. Swift is a general-purpose programming language that takes a modern approach to development.
What this book covers
Chapter 1, Taking the First Steps with Swift, gives a brief introduction to the Swift language. We will also cover the basic Swift language syntax and discuss proper language styles.
Chapter 2, Learning About Variables, Constants, Strings, and Operators, shows how to use variables and constants in Swift. We will also look at the various data types and how to use operators in Swift.
Chapter 3, Using Swift Collections and the Tuple Type, looks at how we can use the Swift collection types to store related data. These collection types are the dictionary, array and set types.
Chapter 4, Control Flow and Functions, covers control flow and functions in Swift. It is essential to understand the concepts in this chapter before going on. Every application that we write, beyond the simple Hello World applications, will rely very heavily on the control flow statements and functions.
Chapter 5, Classes and Structures, dedicates itself to Swift's classes and structures. We'll look at what makes them similar and what makes them different. We'll also look at access controls and object-oriented design. We'll close this chapter out by looking at memory management in Swift.
Chapter 6, Using Protocols and Protocol Extensions, covers both protocols and protocol extensions in detail since protocols are very important to the Swift language. Having a solid understanding of them will help us write flexible and reusable code.
Chapter 7, Protocol-Oriented Design, covers the best practices of protocol-oriented Design with Swift. It will be a brief overview of what is covered in my Swift 3 Protocol-Oriented Programming book.
Chapter 8, Writing Safer Code with Error Handling, looks at Swift's error-handling features. This feature is really important for writing safe code. While we are not required to use this feature in our custom types however it does give us a uniform manner to handle and respond to the error. Apple has also started to use this error handling in their frameworks. It is recommended that we use error handling in our code.
Chapter 9, Custom Subscripting, discusses how we can use custom subscripts in our classes, structures, and enumerations. Subscripts in Swift can be used to access elements in a collection. We can also define custom subscripts for our classes, structures, and enumerations.
Chapter 10, Using Opti...
