The professional development team that brought you two editions of Objective-C for the Absolute Beginners and have taught thousands of developers around the world to write some of the most popular iPhone apps in their categories on the app store, have now leveraged their instruction for Swift. Swift for Absolute Beginners is perfect for those with no programming background, those with some programming experience but no object-oriented experience, or those that have a great idea for an app but haven’t programmed since school. Gary Bennett and Brad Lees are full-time professional iOS developers and have developed a broad spectrum of apps for Fortune 500 companies. The authors have taken their combined 12 years of writing apps, teaching online iOS courses, the experience from their first two iOS books, along with their free online instruction and free online forum to create an excellent training book.Topics include:How to be successful at learning SwiftUsing Swift Playgrounds to learn iOS development quicklyWhat is Object Oriented ProgrammingWhat are Swift classes, properties, and functionsProper user interface and user experience designSwift data types: integers, floats, strings, booleansHow to use Swift data collections: arrays and dictionariesBoolean logic, comparing data, and flow controlWriting iPhone apps from scratchAvoiding Swift pitfallsMany students have a difficult time believing they can learn to write iOS apps or just staying motivated through learning the process. This book, along with the free, live online training sessions, helps students stay motivated and overcome obstacles while they learn to be great iOS developers.
