Swift: Developing iOS Applications. Developing iOS Applications

Jon Hoffman, Andrew J Wagner, Giordano Scalzo

Ebook
The Swift––Developing iOS Applications course will take you on a journey to become an efficient iOS and OS X developer, with the latest trending topic in town. Right from the basics to the advanced level topics, this course would cover everything in detail. We’ll embark our journey by dividing the learning path into four modules. Each of these modules are a mini course in their own right; and as you complete each one, you’ll gain key skills and be ready for the material in the next module.
The first module is like a step-by-step guide to programming in Swift 2. Each topic is separated into compressible sections that are full of practical examples and easy-to-understand explanations. Each section builds on the previous topics, so you can develop a proficient and comprehensive understanding of app development in Swift 2. By the end of this module, you’ll have a basic understanding of Swift 2 and its functionalities.
The second module will be the an easy-to-follow guide filled with tutorials to show you how to build real-world apps. The difficulty and complexity level increases chapter by chapter. Each chapter is dedicated to build a new app, beginning from a basic and unstyled app through to a full 3D game. The last two chapters show you how to build a complete client-server e-commerce app right from scratch. By the end of these modules, you’ll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.
The third and the last module of our course will take an example-based approach where each concept covered is supported by example code to not only give you a good understanding of the concept, but also to demonstrate how to properly implement it.
