BOOK EXCERPT:

Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.

Build robust and scalable iOS and Mac OS X game applicationsAbout This Book- Learn to use and implement the 23 Gang of Four design patterns using Swift 2- Design and architect your code for Swift application development- Understand the role, generic UML design, and participants in the class diagram of the pattern by implementing them in a step-by-step approachWho This Book Is ForThis book is intended for competent Swift developers who want to apply enduring design patterns with Swift to structure and scale their application code.What You Will Learn- Choose the appropriate pattern depending on the problem to be solved- Understand the generic class diagram of each of the 23 GoF patterns and how each object participates in the pattern- Use Swift to implement these patterns even though the language doesn't provide all of the object-oriented programming concepts such as abstract class, interface, and so on- Architect your software to avoid the overuse of memory, time spent on calculations, or high network traffic- Find the best way to organize your code to make it more secure from the outside world- Prepare your code to make it more flexible when the consumer changes or the third-party component hidden code changes- Structure your code to change the algorithm to apply at runtime- Deliver Flyweight responsibility to your objectsIn DetailSwift 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.Style and approachA step-by-step tutorial completed with screenshots and code highlights wherever necessary. Each chapter discusses one or more patterns with its definitions and a simple-to-follow illustration case using a playground or XCText project to implement it with Swift.

"This is the best book on patterns since the Gang of Four's DesignPatterns. The book manages to be a resource for three of the mostimportant trends in professional programming: Patterns, Java, andUML." —Larry O'Brien, Founding Editor, Software DevelopmentMagazine Since the release of Design Patterns in 1994, patterns havebecome one of the most important new technologies contributing tosoftware design and development. In this volume Mark Grand presents41 design patterns that help you create more elegant and reusabledesigns. He revisits the 23 "Gang of Four" design patterns from theperspective of a Java programmer and introduces many new patternsspecifically for Java.

BOOK EXCERPT:

Design Patterns demonstrates how software developers can improve the performance, maintainability, portability, and scalability of their code through the use of the Gang of Four design patterns. After a discussion of patterns methodology, reasons for using design patterns, the book delves into each of the 23 patterns. Each pattern section gives a detailed description of the pattern, refactored from either Boolean logic or simpler, less-maintainable code that you might encounter in the real world, and shows readers how to use the pattern in their code. The text walks readers through making the move from current code to the pattern, lists the benefits of using the pattern, and shows how the pattern performs after the refactoring effort, with a goal throughout of providing practical implementations.

BOOK EXCERPT:

Praise for Design Patterns in Ruby " Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work." —Steve Metsker, Managing Consultant with Dominion Digital, Inc. "This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read." —Peter Cooper "This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book." —Mike Stok " Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby." —Rob Sanheim, Ruby Ninja, Relevance Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code. After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse. Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks. Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.
