Swift

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

Exercism is a great website where I was able to have some very interesting challenges.

Relaxed. Encouraging. Supportive.

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've built a couple of iOS apps in Swift, and love the syntax. It truly is my favorite strongly-typed language to work in. I'm excited to share what I've learned, and learn alongside others!

I've been developing iOS apps since the iOS 3.0 days. I learned Swift when it first released with the help of exercism.io. I enjoy helping others learning the language, I always seem to learn a bit more myself.

I'm an experienced iOS Developer and used Swift in many projects. Swift is the most lovable programming language I've ever developed. For, it's so modern, incredibly fast and safe by design.

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'm a professional iOS Developer, leaning towards a functional approach and mathematics based approach. I've been using Swift professionally since 2.0 was released.
Fun. Challenging. Interesting
