Apple computers has come up with new programming language
Swift is a new programming language for iOS and OS X apps that
builds on the best of C and Objective-C, without the constraints of C
compatibility. Swift adopts safe programming patterns and adds modern features
to make programming easier, more flexible, and more fun. Swift’s clean slate,
backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an
opportunity to re-imagine how software development works. Development on Swift began in 2010 by Chris Lattner, with the eventual collaboration of many other
programmers. The Swift Programming
Language, a free 500-page manual, was also released at WWDC.
Swift has been years in the making. Apple laid the foundation
for Swift by advancing our existing compiler, debugger, and framework
infrastructure. We simplified memory management with Automatic Reference
Counting (ARC). Our framework stack, built on the solid base of Foundation and
Cocoa, has been modernized and standardized throughout. Objective-C itself has
evolved to support blocks, collection literals, and modules, enabling framework
adoption of modern language technologies without disruption. Thanks to this
groundwork, we can now introduce a new language for the future of Apple
software development.
Swift feels familiar to Objective-C developers. It adopts the
readability of Objective-C’s named parameters and the power of Objective-C’s
dynamic object model. It provides seamless access to existing Cocoa frameworks
and mix-and-match interoperability with Objective-C code. Building from this
common ground, Swift introduces many new features and unifies the procedural
and object-oriented portions of the language.
Swift is friendly to new programmers. It is the first
industrial-quality systems programming language that is as expressive and
enjoyable as a scripting language. It supports playgrounds, an innovative
feature that allows programmers to experiment with Swift code and see the
results immediately, without the overhead of building and running an app.
Swift combines the best in modern language thinking with wisdom
from the wider Apple engineering culture. The compiler is optimized for
performance, and the language is optimized for development, without
compromising on either. It’s designed to scale from “hello, world” to an entire
operating system. All this makes Swift a sound future investment for developers
and for Apple.
Swift is a fantastic way to write iOS and OS X apps, and will
continue to evolve with new features and capabilities. Swift uses Automatic Reference Counting (ARC) to manage memory. Swift provides the
weak
and un-owned
keywords that allow the programmer to prevent
strong reference cycles from occurring.
