What is Swift?
Swift is a multi-paradigm compiled programming language created by Apple for iOS and OS X development. Introduced at Apple's 2014 Worldwide Developers Conference, 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 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 provides its own versions of all fundamental C and Objective-C types, including Int for integers, Double and Float for floating-point values, Bool for Boolean values, and String for textual data. Swift also provides powerful versions of the two primary collection types, Array and Dictionary, as described in Collection Types.
Some of the Features
- Better type safety
- Better memory management
- Multiple return values and
- Bunch of functional paradigms.
Swift does not create pointers and other unsafe accessors by default. Swift introduces true named parameters and retains key Objective-C concepts, including protocols, closures and categories, often replacing former syntax with cleaner versions and allowing these concepts to be applied to other language structures, like enums.
