REPL and Playground

Xcode provides the Read Eval Print Loop (REPL) command-line environment to experiment with the Swift programming language without the need to write a program. Also, Swift provides Playgrounds, which enable us to test Swift code snippets quickly and see the results in real time via a visual interface. Source codes for the first ten chapters of this book are provided as Playgrounds in the GitHub repo and Packt Publishing website.
