What is Swift?
Swift is a modern, general-purpose, and multi-paradigm programming language that was developed by Apple and first released in 2014. It is designed to be fast, safe, expressive, and easy to use. Swift is mainly used for developing applications for iOS, macOS, watchOS, tvOS, and Linux. Swift can also be used for scripting, web development, data analysis, machine learning, and more. Swift has a rich set of features, such as:
Type inference and type safety
Optionals and nil coalescing
Closures and higher-order functions
Classes and protocols
Extensions and generics
Enums and pattern matching
Error handling and defer statements
Memory management and ARC
Concurrency and async/await
Property wrappers and result builders
Interoperability with Objective-C and C
Swift has a comprehensive documentation that covers the language syntax, grammar, standard library, design patterns, best practices, and more. You can access the documentation online at https://docs.swift.org/swift-book/ or download it as a PDF file at https://docs.swift.org/swift-book/SwiftStandardLibrary.pdf.
What is Epub?
Epub is a short name for electronic publication. It is an open and free standard for creating and distributing digital books. Epub files have the extension .epub and can contain text, images, audio, video, metadata, interactivity, and more. Epub files are based on HTML, CSS, XML, and ZIP technologies. Epub files can be read by various software applications and devices, such as:
E-readers (e.g., Kindle, Kobo, Nook)
Smartphones and tablets (e.g., iPhone, iPad, Android)
Computers (e.g., Windows, Mac, Linux)
Browsers (e.g., Chrome, Firefox, Safari)
Ebook management tools (e.g., Calibre)
Epub has several advantages over other formats for digital books, such as:
It is flexible and adaptable to different screen sizes and orientations.
It supports reflowable text and dynamic layout.
It allows customization of fonts, colors, styles, and themes.
It supports multimedia content and interactivity.
It supports accessibility features and internationalization.
It is easy to create and edit.
Epub has several versions that have different features and specifications. The latest version is Epub 3.2 which was released in 2019. You can learn more about Epub at https://www.w3.org/publishing/epub3/epub-overview.html or download the specification at https://www.w3.org/publishing/epub32/epub-spec.html.
