Book description

Through this guide's carefully constructed explanations and examples, you will develop an understanding of Swift grammar and the elements of effective Swift style - all thoroughly revised for Swift 5.3 and Xcode 12.

 

Based on Big Nerd Ranchs popular Swift training and its well-tested materials and methodology, this guide teaches concepts and coding through hands-on exercises. You will explore Swift features in Xcode playgrounds, and you will end by building sample apps for the command line and for macOS and iOS.

 

After working through the book, you will have the skills to confidently dive into learning app development for Apple platforms like iOS and macOS.
