Open Source Swift Protocols

Vienna is an open source Mac OSX RSS reader with support for RSS/Atom/JSON feeds, article storage and management via a SQLite database, written in Objective-C and Cocoa. Feeds can be accessed directly, or through a syncing service supporting the Open Reader API, like BazQux.com, FreshRss.org, FeedHQ.org, InoReader.com or TheOldReader.com. Development now happens on GitHub: https://github.com/ViennaRSS/vienna-rss

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.

NetNewsWire is a free and open source RSS reader for Mac, iPhone, and iPad. NetNewsWire shows you articles from your favorite blogs and news sites and keeps track of what you’ve read. This means you can stop going from page to page in your browser looking for new articles to read. Do it the easy way instead: let NetNewsWire bring you the news. And, if you’ve been getting your news via Facebook and Twitter, with their ads, algorithms, user tracking, outrage, and misinformation, you can switch to NetNewsWire to get news directly and more reliably from the sites you trust.

gitignore.io is an open-source service and codebase that generates ready-to-use .gitignore files tailored to your project’s stack. It aggregates community-maintained templates for programming languages, frameworks, IDEs, operating systems, and tooling, and then composes them into a single file on demand. You can access it from a clean web UI, a simple REST API, or the command line, making it easy to script into new-project scaffolds and automation. The generator accepts multiple technologies in one request, normalizes duplicates, and orders rules sensibly so the result is readable and effective. Templates are versioned and updated over time as tools evolve, helping teams avoid accidentally committing build artifacts, credentials, caches, and other noisy files. The repository includes documentation, example invocations, and contribution guidelines so users can add or refine templates.
