Swift Programming Language Learning-Introduction to Swift

Sometimes, it may take some time to read English documents. If you read Chinese documents, you may be afraid of inaccurate translation. In some cases, you do not need to write any word. If the translation is inaccurate, ambiguity may occur, so let's take a look at Swift in this way.

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 reimagine how software development works.

Swift is a brand new programming language used to write iOS and OS X applications. Swift combines the advantages of C and Objective-C without restrictions on C compatibility. Swift adopts a secure programming mode and adds many new features, which makes programming simpler, more flexible, and more interesting. Swift is based on the mature and popular Cocoa and Cocoa Touch frameworks, trying to rethink the new revolution in software development.

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 ). ourframework 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 development has been brewing for a long time. To support Swift, Apple improved the compiler, debugger, and framework structure. We use Automatic Reference count (ARC) to simplify memory management. We build and standardize the framework Stack Based on Foundation and Cocoa. Objective-C itself supports blocks, set syntax, and modules, so the framework can easily support modern programming language technology. Thanks to these basic work, we can now release such a new language for future 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 mixand-match interoperability with Objective-C code. building from this common ground, Swift introduces extends new features and unifications the procedural and object-oriented portions of the language.

Objective-C developers are not unfamiliar with Swift. It uses the naming parameters and Dynamic Object Model of Objective-C, which can seamlessly connect to the existing Cocoa framework and be compatible with Objective-C code. On this basis, Swift also has many new features and supports procedural and object-oriented programming.

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 building of and running an app.

Swift is also very friendly for beginners. It is the first programming language that meets industrial standards and is as expressive and interesting as a scripting language. It supports code preview. This revolutionary feature allows programmers to run Swift code without compiling and running applications and view results in real time.

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 combines the essence of modern programming languages with the wisdom of Apple's engineer culture. The compiler optimizes the performance, and the programming language optimizes the development. The two are mutually independent. Swift can be used to develop small programs such as "hello, world" or a complete operating system. All these features make Swift a worthwhile investment for developers and apple.

Swift is a fantastic way to write iOS and OS X apps, and will continue to evolve with new features and capabilities. our goals for Swift are ambitious. we can't wait to see what you create with it.

Writing iOS and OS X applications with Swift will be an excellent experience, and Swift will continue to develop new features and compatibility. We are confident in Swift and can't wait to see the application developed by Swift.
