What is Swift?
Swift is a general-purpose programming language developed by Apple Inc. It was designed to be an expressive, easy-to-use language that would enable developers to quickly build powerful apps. Swift is based on the Objective-C language, but has been modernized with a cleaner syntax and more robust features.
Swift supports both object-oriented and functional programming paradigms, making it a great choice for developers who want to build powerful, yet intuitive applications. It also supports type inference, which allows developers to write code that is more concise and readable.
