Functional Programming in Swift

Swift opens up a whole new world of programming that we’re going to explore in this book. To quote Swift’s creator, Chris Lattner:

“Objective-C without the C” implies something subtractive, but 
Swift dramatically expands the design space through the 
introduction of generics and functional programming concepts.

We’ll explain the concepts behind functional programming and how Swift makes it easy to leverage them in a pragmatic way, in order to write clearer and more expressive code.
