Swift is a new programming language for iOS and OS X applications, based on C and objective-c, without some of the compatibility constraints of C. Swift uses a secure programming model and adds modern features to make programming easier, more flexible, and more fun. The interface is based on the cocoa and cocoa touch framework, which is popular with the people, and shows the new direction of software development.

Swift has existed for many years. Apple is based on an existing compiler, debugger, and framework as its infrastructure. Simplify memory management with arc (Automatic Reference counting, auto reference count). Our framework stack is always based on cocoa. Objective-c Evolution supports blocks, collection literal, and modules, allowing the framework of modern languages to be used without deep access. Thanks to these basic work, the new programming language can be introduced in Apple software development (by Gashero).

OBJECTIVE-C developers will feel Swift's déjà vu. Swift uses objective-c named parameters and a dynamic object model. Provides interoperability with the cocoa framework and the mix-and-match. Based on these fundamentals, Swift introduces a number of new features and a combination of process-oriented and object-oriented features.

　

Swift is also friendly to the new programmer. He is an industrial-quality system programming language, yet as friendly as a scripting language. He supports playground, allowing programmers to experiment with a swift code feature and immediately see results without having to build and run an application in a hassle.

Swift integrates modern programming language ideas and the wisdom of Apple's engineering culture. Compilers are optimized for performance, and languages are optimized for development without compromising on each other. (by Gashero) can start from "Hello, World" to learn and transition to the entire system. All of this makes swift a source of innovation for Apple software developers.

Swift is a fantastic way to write iOS and OSX apps, and will continue to drive the introduction of new features. We can't wait to see you do something with him.
