The document contains various Swift programming functions demonstrating concepts such as function currying, regex matching, string manipulation, and simple UI actions. It includes code for defining and utilizing functions, handling regular expressions, and implementing animation for UI elements. Additionally, it touches upon data structures and API management within a ViewController class context.
