Swift Fundamentals

Book excerpt: Swift is an excellent way of writing software if it's running code for tablets, desktops, servers, or any other devices. It's a simple, fast, and collaborative programming language that blends the best of modern language thought process with the knowledge of the broader culture of Apple engineering and the dynamic contributions of its open-source community. The compiler is performance-optimized, and the language is designed for growth, without compromising. Swift is perfect for fresh programmers. It's said to be a programming language of industrial standard, which is as concise and exciting as a scripting language. Swift blends powerful inferences and patterns matching with new, lightweight syntax, enabling simple and succinct expression of complex ideas. Code is, therefore, not only easier to write but also useful to read and manage. Swift has been in development phases for years, and it keeps growing with new features and functionality. Swift code enables users to experiment.
