Join the Swift Track
Swift is a modern open-source language with the aim of making programming simple things easy, and difficult things possible while still being fast and safe by design. Swift can run in scripting mode in the included REPL or it can be compiled with full support for C and Objective-C interoperability.

About Swift

//
// HelloWorld.swift
//

struct HelloWorld {
    static func hello(_ text: String = "World") -> String {
        return "Hello, \(text)!"
    }
}

Swift is a modern open source programming language that runs on macOS, Linux and on Windows using a linux subsystem.

Swift was developed initially by Apple to interoperate with their key frameworks, Cocoa and CocoaTouch, both of which are mostly implemented in Objective-C.

Swift is influenced by a large number of existing programming languages, and it incorporates concepts from a wide range of programming methods. Everything from scripting to object oriented and functional programming.

Apple refers to Swift as a "protocol oriented programming language" and has expressed the goal of eventually making Swift useful for everything from scripts to an operating system.


This Swift Tour is an introduction the language on Apple's Public Developer Website.


Wikipedia's Swift Page giving a good, Wikipedia-styled overview.


Swift is documented in The Swift Programming Language - again, on Apple's Public Developer Website - and in the iBooks Store. The ePub version is also available on Swift.org.

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.

I love swift! I've been an iOS developer since iOS 3 and developing in Swift for over 2 years now at a large iOS company. I love the community surrounding swift, everyone has been so supportive. I'm hoping to help the developers grow and learn somethings myself along the way as well.

I've been programming for about 40 years, rolling through the ranks of Basic, Pascal, C, Fortran, COBOL, OCaml, and F#. Now I use Swift for most of my programming, having picked it up with the 3.0 release. Also, I can probably eat more tacos than you.

I have been programming for around 5 years using various languges and technologies. Currently, I focus on Swift and iOS development. I am excited to mentor for Swift and join Exercism's Objective-C track as a student!

I love Swift because of how simple and powerful the language is. I am constantly learning cool new ways of writing good Swift code as I work on an iOS app day to day.
Fun. Challenging. Interesting
