The Basics of Swift The Swift programming language was first introduced in June 2014 at Apple’s Worldwide Developers Conference (WWDC). Swift was a surprise to everyone: Apple had - Selection from Learning Swift Book. Swift 4 uses the same runtime as the existing Obj-C system on Mac OS and iOS, which enables Swift 4 programs to run on many existing iOS 6 and OS X 10.8 platforms. Audience This tutorial is designed for software programmers who would like to learn the basics of Swift 4 programming language from scratch.
Swift is a new programming language for developing apps for IOS and Mac OS, and it is destined to become the foremost computer language in the mobile and desktop space. This Swift tutorial series will help you to get started in the Swift programming language.
Required Knowledge
To learn Swift Programming language, you haven't needed any previous programming knowledge, but the basic understanding of any other programming languages will help you to understand the Swift programming concepts quickly.
Swift Example
A quick look at the example of Hello, World! In Swift programming. A detailed description is given in the Swift Basic Syntax page.
Program Output:
The above example has been used to print 'Hello World' on the screen.

Best Way To Learn Swift
This up to date guide will teach you the basics of the Swift programming language.
If you’ve ever tried to learn Swift, you’ll know that there are tons of outdated resources floating around the internet because Swift is in its infancy and Apple updates the language so often.
It’s a tremendous effort, but I’ve kept the following tutorials up to date and will continue to do so!
With that said, let’s dive into the lessons!
Psst! Download and print out my trusty Swift Syntax Cheat Sheet.
