Swift is an object-oriented programming language for iOS and OS X development which is recently introduced by Apple at its WWDC 2014. It is intended to coexist with Objective-C, the current programming language for Apple operating systems. Swift is designed to be more resilient against erroneous code. It is built with the LLVM compiler.
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 reimagine how software development works. On June 2, 2014, the WWDC conference app became the first publicly released Swift app.
Example code
let people = ["Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25]
for (name, age) in people {
println("\(name) is \(age) years old.")
}
Safe
Swift pairs increased type safety with type inference, restricts direct access to pointers, and automatically manages memory—making it easy to create secure, stable software.Modern
Swift includes optionals, generics, tuples, and other modern language features. Inspired by and improving upon Objective-C. Swift code feels natural to read and write.Powerful
Take advantage of powerful pattern matching in Swift to write simple, expressive code. Format strings naturally with string interpolation. Use frameworks like Foundation and UIKit directly from Swift.Interactive
Use playgrounds to experiment with new technologies, analyze problems, and prototype user interfacesFast
The Swift compiler applies advanced code analysis to tune your code for performance, letting you focus on writing great apps instead of on implementing complex optimizations.For more details and for learning Swift Programming Language visit
