    FeedKit

    FeedKit

    An RSS, Atom and JSON Feed parser written in Swift

    FeedKit is an RSS, Atom and JSON Feed parser written in Swift. Build a URL pointing to an RSS, Atom or JSON Feed. A common scenario in UI environments would be parsing a feed asynchronously from a user-initiated action, such as the touch of a button. Remember, you are responsible for manually bringing the resulting closure to whichever queue is appropriate. Usually to the Main thread, for UI apps, by calling DispatchQueue.main.async. FeedKit adopts Swift 5 Result type, as Result<Feed, ParserError>, and as such, if parsing succeeds you should now have a Strongly Typed Model of an RSS, Atom or JSON Feed, within the Feed enum. The RSS and Atom feed Models are rather extensive throughout the supported namespaces.
