Swift

Swift is a general-purpose, compiled programming language developed by Apple Inc. for their platforms and Linux. Swift is designed to be easy to read and write, and to be safe and modern. It is intended to be more concise than Objective-C, the language it was designed to replace, and more expressive than C-based languages.

Some key features of Swift include:

• Type safety: Swift is a type-safe language, which means that every variable and constant must be explicitly defined with a type. This helps to prevent common programming errors, such as trying to add a string to an integer.
• Optionals: Swift introduces the concept of optionals, which allow developers to handle the absence of a value in a concise and safe way.
• Closures: Swift includes support for closures, which are blocks of code that can be passed around and executed at a later time. Closures can be used to simplify and make code more readable.
• Protocol-oriented programming: Swift introduces the concept of protocols, which allow developers to define a set of methods or properties that can be adopted by a class, structure, or enumeration. This allows for more flexible and modular design of code.
• Safety: Swift includes a number of features that help to prevent common programming mistakes and improve code safety, such as automatic memory management, type inference, and error handling.

Swift is used to build applications for iOS, iPadOS, macOS, watchOS, and Linux. It is a popular choice for developing native apps for these platforms due to its performance, ease of use, and modern syntax.
