Learning Swift 4 by Building Applications is a book that teaches the basics of Swift in the context of iOS. If you finish the book, you should be able to develop small-to-medium mobile apps. You will know how to create the app UI in storyboard using Xcode, how to load and display images fetched from the cloud, how to save and load information between different sessions of the app, and how to share data between all users of the app using the cloud.

The book is designed for beginners who have little or no experience with Swift or any other programming language. The first couple of chapters introduce the Swift and the core programming principals, which are used throughout the process of software development. The rest of the book discusses the Swift development of iOS mobile applications. We will explain how to use open source libraries to achieve rapid software development and develop apps that are consuming information and images from the c l oud.

, Swift Basics Variables and Functions , discusses the basics of the Swift language, starting from the A, B, and C.

, Getting Familiar with Xcode and Playgrounds , presents the Xcodea free IDE that we will use when developing Swift. We shouldn't forget that Xcode is developed by Apple and that the playgrounds are the perfect place for learning Swift step by step.
