Introduction iOS SWIFT Programming Language

This Article is prepared by Dhara Dhanesha

Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, Swift is friendly to new programmers.

Swift can be said similar to objective C. 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.

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.

A language is easier to learn and help developer while processing as it has interactive playground. A Boon – the Sandbox feature--”Where one can run stuff in playgrounds to be able to change code on the fly without recompiling”.

Developer's view - “Having to invest the time into learning Objective -C was the biggest hurdle, that hurdle is now gone”.

Hence, Swift is expressive, designed to make its easy to experiment in a playground or to quickly build a script. A complete program can be a single line of code. Now to scale most complex apps that one dreams will be easier to develop.
