Application ProspectsAs an independent launch of Apple's supported development language, there have been a number of application demonstrations and collaborative development company testing, I believe it will be more widely used in the future. [4] In a sense, swift, as Apple's new business strategy, will attract more developers to get started, increasing the number of applications that the App Store and Mac store are already strong.Application ScopeSwift is a new programming language for writing IOS and OS X apps. Swift combines the advantages of C and objective-c and is not limited by C compatibility. Swift uses a secure programming model and adds a lot of new features, which makes programming easier, more flexible, and more fun. Swift is based on the mature and beloved Cocoa and Cocoa Touch framework, and his advent will redefine software development. Swift's development began a long time ago. To lay the groundwork for Swift, Apple has improved the compiler, debugger, and framework structure. We use automatic reference counting (Automatic Reference counting, ARC) to simplify memory management. We build and standardize the framework stack based on foundation and cocoa. The 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 publish such a new language for future development of Apple software. Objective-c developers are not unfamiliar with Swift. It uses objective-c named parameters and the dynamic object model to seamlessly connect to the existing Cocoa framework and can be compatible with OBJECTIVE-C code. On top of this, Swift has many new features and supports procedural and object-oriented programming.Operational BenefitsSwift is also very friendly for beginners. It is the first programming language that satisfies both industry standards and is as expressive and interesting as the scripting language. It supports code previews, a revolutionary feature that allows programmers to run Swift code without compiling and running the application and view the results in real time.Application BenefitsSwift combines the essence of modern programming language with the wisdom of Apple's engineer culture. The compiler optimizes performance and the programming language optimizes development, with both the fish and the paws. Swift can be used to develop small programs such as "Hello, world" or to develop a complete set of operating systems. All of these features make Swift a worthwhile investment for both developers and Apple. The above information from Baidu
