What is Swift?
Swift is a modern programming language developed by Apple, introduced in 2014, and optimized for iOS, macOS, watchOS, and tvOS. It offers high performance and places great emphasis on security with features like optionals and a strict type system. The clear syntax makes Swift easy to learn, and with Swift Playgrounds in Xcode, developers can test code in real time. As an open-source project, Swift is continuously improved. The language works seamlessly with Objective-C, making integration into existing projects easier. Swift provides a flexible foundation for apps across the entire Apple ecosystem, from mobile applications and desktop software to applications for wearable devices and televisions.
Shortcut Swift
Swift is Apple's power language for the entire ecosystem — fast, secure, and with clear syntax that makes it easy to get started. Thanks to Swift Playgrounds, you can test code directly, and as an open-source project, Swift continues to grow. The seamless collaboration with Objective-C makes it perfect for both new and existing projects.
Rapid, reliable, and straightforward
