in Swift, use formatted methods directly on the types you want to format, optionally using FormatStyle and its subtypes to customize formatter output. This approach supports dates, integers, floating-point numbers, measurements, sequences, and person name components. Foundation caches identically-configured formatter instances internally, allowing you to focus on your app’s formatting needs.
