Learn basics of Swift
Swift is a multi-paradigm programming language with a modern approach, intended as a replacement for C-based languages (C, C++, and Objective-C), designed for iOS, OSX, and WatchOS, and to work within Apple’s existing frameworks. Our team created a guide for all difficulty levels and prepared a huge collection of videos that can only boost your learning efforts. Coders can subscribe to live streaming channels and chat with more experienced Swift developers.
Introduction to Swift Programming Language (Reference)
Swift is a general-purpose, multi-paradigm, compiled programming language created for iOS, OS X, watchOS, tvOS and Linux developed by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program.
Swift supports the core concepts that made Objective-C flexible, notably dynamic dispatch, widespread late binding, extensible programming and similar features. These features also have well known performance and safety trade-offs, which Swift was designed to address. For safety, Swift introduced a system that helps address common programming errors like null pointers, as well as introducing syntactic sugar to avoid the pyramid of doom that can result. For performance issues, Apple has invested considerable effort in aggressive optimization that can flatten out method calls and accessors to eliminate this overhead. More fundamentally, Swift has added the concept of protocol extensibility, an extensibility system that can be applied to types, structs and classes. Apple promotes this as a real change in programming paradigms they refer to as "protocol-oriented programming".
Swift History (Reference)
Development on Swift language was begun in July 2010 by Chris Lattner, with the eventual collaboration of many other programmers at Apple. Swift took language ideas "from Objective-C,Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list". On June 2, 2014, the Worldwide Developers Conference (WWDC) application became the first publicly released app written in Swift. A beta version of the programming language was released to registered Apple developers at the conference, but the company did not promise that the final version of Swift would be source-compatible with the test version. Apple planned to make source code converters available if needed for the full release.
The Swift Programming Language, a free 500-page manual, was also released at WWDC, and is available on the iBooks Store as well as the official website.
Swift reached the 1.0 milestone on September 9, 2014, with the "Gold Master" of Xcode 6.0 for iOS. Swift 1.1 was released on October 22, 2014, alongside the launch of Xcode 6.1. Swift 1.2 was released on April 8, 2015, in conjunction with Xcode 6.3. Swift 2.0 was announced at WWDC 2015, and was made available for publishing apps in the App Store in September 21, 2015. A Swift 3.0 roadmap was announced on the Swift blog on December 3, 2015. However, prior to that an intermediate Swift 2.2 version embracing new syntax and features has been introduced. This also shuns certain outdated components including Tuple splat syntax, C-style for loops and ++ and -- operators.
Swift won first place for Most Loved Programming Language in the Stack Overflow Developer Survey 2015 and second place in 2016.
Google is said to be considering using Swift as a First Class Language in its Android operating system.
- XCODE - The Xcode IDE is at the center of the Apple development experience. Tightly integrated with the Cocoa and Cocoa Touch frameworks, Xcode is an incredibly productive environment for building apps for Mac, iPhone, iPad, Apple Watch, and Apple TV.
- GHUNIT - GHUnit is a test framework for Mac OS X and iOS. It can be used standalone or with other testing frameworks like SenTestingKit or GTM.
- EUREKA - Eureka is a library to create dynamic table-view forms from a DSL specification in Swift. This DSL basically consists of Rows, Sections and Forms. A Form is a collection of Sectionsand a Section is a collection of Rows.
- RX SWIFT - Rx is a generic abstraction of computation expressed through Observable
interface. Like the original Rx, its intention is to enable easy composition of asynchronous operations and event/data streams.
- OBJECTMAPPER - ObjectMapper is a framework written in Swift that makes it easy for you to convert your model objects (classes and structs) to and from JSON.
- REFACTORATOR - Refactorator is an Xcode plugin for refactoring Swift & now Objective-C code. It will rename public or internal vars, functions, enums etc. For private and local entities use Xcode’s existing “Edit All in Scope” functionality.
- SPRING - Spring is a library to simplify iOS animations in Swift. It has grown into a full-blown animation library that supports every View, Transitions, Loading Animation and a lot more.
