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.

This book verges on the surreal in its awfulness. It reads like a 1982 VCR manual translated from Japanese into English by a native speaker of Italian. Truly - nearly every paragraph has some terrible linguistic convolution stunning in its cluelessness. Imagine 2001's HAL, had he been an autistic child. The author thinks nothing of beginning any number of successive sentences with the same words and seems to regard all articles and conjunctions as interchangeable. Misspellings, typos, syntax & tense errors, and word misusage all abound. The result is a droning, bizarrely robotic glossolalia overflowing with numbing repetition punctuated by strange quirks and distractions, all of which achieves the goal of rendering an already esoteric subject opaque.Nor does the ugliness stop there. The ebook includes delights such as entire pages with a single sentence and other layout disasters that suggest a computer generated text untouched by any human being. Vast expanses of white space interrupt the text; perhaps half the pages are more than half blank. It appears to be a draft website or classroom presentation dumped to text. Printed, there'd be enough room to write an entirely new (and one hopes, better) text in the white space provided.Perhaps the author is a non-native speaker of English, but that in no way excuses the publisher for releasing this half-baked abortion. One can only assume Packt employs no editors and vetted this shameful mess not at all.
