If you interested in exploring it, then this book is what you need. The book begins with an introduction to the basic building blocks of Swift 4, its syntax and the functionalities of Swift constructs. Then, introduces you to Apple's Xcode 9 IDE and Swift Playgrounds, which provide an ideal platform to write, execute, and debug the codes thus initiating your development process. Next, you'll learn to bundle variables into tuples, set order to your data with an array, store key-value pairs with dictionaries and you'll learn how to use the property observers. Later, explore the decision-making and control structures in Swift and learn how to handle errors in Swift 4. Then you'll, examine the advanced features of Swift, generics and operators, and then explore the functionalities outside of the standard library, provided by frameworks such as Foundation and UIKit. Also, you'll explore advanced features of Swift Playgrounds. At the end of the book, you'll learn server-side programming aspect of Swift 4 and see how to run Swift on Linux and then investigate Vapor, one of the most popular server-side frameworks for Swift.

Swift on Ubuntu

The Linux operating system is a dominant force in the world of backend servers, so to be of any use for server-side development, Swift needs to be available on Linux. Fortunately, part of the open source release of Swift includes the Swift toolchain on Linux. Let's get it up and running with a "Hello World" program in Swift on Linux.

Getting started

This recipe will use Ubuntu 16.04, as this is a very popular and widely used Linux distribution, and 16.04 is the latest Long-Term Support (LTS) version. Additionally, pre-built binaries of the Swift toolchain are provided for this distribution by the Swift open source team. As a Mac user, I have tested this process on an instance of Ubuntu, running...
