FeedKit

The `Feed` enum automatically detects and parses RSS, Atom, and JSON feeds from a single initialization, as shown in the universal reading example, simplifying handling of unknown feed types.

Includes support for iTunes, Media RSS, Dublin Core, and other namespaces, enabling detailed parsing of podcast and media feeds, which is explicitly listed in the README's namespace section.

Can read feeds from URL strings, local files, remote URLs, raw data, or XML/JSON strings, as detailed in the initializers section, providing multiple ways to load feed data.

Allows generating properly formatted XML and JSON feed strings from Swift models using `toXMLString` and `toJSONString` methods, useful for creating syndicated content.
