Overview of this book

Swift is the definitive language of Apple development today. It’s a vital part of any iOS and OS X developer’s skillset, helping them to build the most impressive and popular apps on the App Store—the sort of apps that are essential to iPhone and iPad users every day. With version 3.0, the Swift team have added new features to improve the development experience—making it easier to get the results you want and customers expect. Inside, you’ll find the key features of Swift 3.0 and quickly learn how to use the newest updates to your development advantage. From Objective-C interoperability to ARC, to closures and concurrency, this advanced Swift guide will develop your expertise and make you more fluent in this vital programming language. We give you in-depth knowledge of some of the most sophisticated elements of Swift development including protocol extensions, error-handling, design patterns, and concurrency, and guide you on how to use and apply them in your own projects. You'll see how even the most challenging design patterns and programming techniques can be used to write cleaner code and to build more performant iOS and OS X applications. By the end of this book, you’ll have a handle on effective design patterns and techniques, which means you’ll soon be writing better iOS and OS X applications with a new level of sophistication and control.

What is a programming style guide?


Coding styles are very personal, and every developer has his or her own preferred style. These styles can vary from language to language, person to person, and also over time. The personal nature of coding styles can make it difficult to have a consistent and readable code base when numerous individuals are contributing to the code.

While most developers might have their own preferred styles, the recommended or preferred style between languages can vary. As an example, in C#, when we name a method or function, it is preferred that we use camel case with the first letter being capitalized. While in most other languages, such as C, Objective-C, and Java, it is also recommended that we use camel case, but the programmers working in these languages prefer that the first letter be lowercase.

The best applications are coded properly, and by properly we do not just mean that they function correctly but also that they are easy to maintain and the code is easy to...
