Learn iOS design patterns with Swift! This book starts with basic patterns like MVC, Delegate and Strategy, and then moves into more advanced patterns such as the Factory, Prototype, Multicast Delegate, Flyweight, Command, and more. Design patterns are incredibly useful, no matter which language or platform you develop for. Every developer should know how to implement them, and most importantly, when to apply them. That's what you're going to learn in this book! Design Patterns: Elements of Reusable, Object-Oriented Software, the first book to ever describe design patterns, inspired the revolutionary idea of reusable, template solutions to common software development problems.
