Book Description


Swift is a multi-paradigm language. It has expressive features familiar to those
used to work with modern functional languages, while also keeping the object-
oriented features of Objective-C. It remains compatible with Apple's legacy
codes and frameworks. A design pattern systematically names, motivates, and
explains a general design that addresses a recurring design problem in object-
oriented systems. It describes the problem, the solution, when to apply the
solution, and its consequences. It also gives implementation hints and examples.
Knowledge about design patterns is also one of the best ways to make you
different compared to other low-level developers.


This book shows you how to use Swift 2 to learn about 23 Gang of Four (GoF)
design patterns, and is organized into three categories. The book will present
you the five creational patterns, followed by the seven structural patterns, and
finishing with the 11 behavioral patterns as defined by the GoF. Each chapter
will introduce the pattern by defining its role, which common problems the
pattern should be used for, its generic UML representation, how each objects
presented in the class diagram participate in the pattern, and what the role of
each of these objects is. The book then presents you with a concrete case as an
illustration that will be used to implement the pattern using Swift.
