Hands-on Design Patterns in Swift provides a complete overview of how to implement classic design patterns in Swift. Swift is a modern language, and for users coming from a purely object-oriented language background, it may feel overwhelming. It has peculiar characteristics that create new programming paradigms, such as protocol programming, and appropriate solutions to problems such as type erasure. Both of these are covered in this book.
Design patterns do not live in isolation, however, but they help to solve real-world problems. Particular attention is given to presenting them in a number of realistic scenarios.
The goal of Swift is to create robust and maintainable apps, be they mobile or server. However, well-known techniques such as dependency injection and automatic testing are taken from other programming languages.
Finally, since most of the modern software relies upon open source, the final chapter shows how to release and maintain a Swift open source package.
