<p>This book is based on Swift 3 Developer preview version and aims at simplifying the functional programming (FP) paradigms making it easily usable, by showing you how to solve many of your day-to-day development problems.</p> <p>Whether you are new to functional programming and Swift or experienced, this book will strengthen the skills you need to design and develop high-quality, scalable, and efficient applications.</p> <p>The book starts with functional programming concepts, the basics of Swift 3, and essential concepts such as functions, closures, optionals, enumerations, immutability, and generics in detail with coding examples.</p> <p>Furthermore, this book introduces more advanced topics such as function composition, monads, functors, applicative functors, memoization, lenses, algebraic data types, functional data structures, functional reactive programming (FRP), protocol-oriented programming (POP) and mixing object-oriented programming (OOP) with functional programming (FP) paradigms.</p> <p>Finally, this book provides a working code example of a front-end application developed with these techniques and its corresponding back-end application developed with Swift.</p>
