Usage

Build a URL pointing to an RSS, Atom or JSON Feed.

let feedURL = URL(string: "http://images.apple.com/main/rss/hotnews/hotnews.rss")!

Get an instance of FeedParser

let parser = FeedParser(URL: feedURL) // or FeedParser(data: data) or FeedParser(xmlStream: stream)

Then call parse or parseAsync to start parsing the 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. e.g.

// Parse asynchronously, not to block the UI.
parser.parseAsync(queue: DispatchQueue.global(qos: .userInitiated)) { (result) in
    // Do your thing, then back to the Main thread
    DispatchQueue.main.async {
        // ..and update the UI
    }
}

Remember, you are responsible to manually bring the result closure to whichever queue is apropriate. Usually to the Main thread, for UI apps, by calling DispatchQueue.main.async .

Alternatively, you can also parse synchronously.

let result = parser.parse()

Parse Result

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:

switch result {
case .success(let feed):

    // Grab the parsed feed directly as an optional rss, atom or json feed object
    feed.rssFeed

    // Or alternatively...
    switch feed {
    case let .atom(feed):       // Atom Syndication Format Feed Model
    case let .rss(feed):        // Really Simple Syndication Feed Model
    case let .json(feed):       // JSON Feed Model
    }

case .failure(let error):
    print(error)
}

The RSS and Atom feed Models are rather extensive throughout the supported namespaces. These are just a preview of what's available.
