Open Source Swift Formats and Protocols for Mobile Operating Systems

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.

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.

ObjectMapper is a framework written in Swift that makes it easy for you to convert your model objects (classes and structs) to and from JSON. Once your class implements Mappable, ObjectMapper allows you to easily convert to and from JSON. Use functions to validate JSON prior to object serialization provide an existing cached object to be used for mapping, return an object of another type (which also conforms to BaseMappable) to be used for mapping. For instance, you may inspect the JSON to infer the type of object that should be used for mapping. ObjectMapper supports dot notation within keys for easy mapping of nested objects. ObjectMapper also supports custom transforms that convert values during the mapping process. To use a transform, simply create a tuple with map["field_name"] and the transform of your choice on the right side of the <- operator.

Wrap is an easy-to-use Swift JSON encoder. Don't spend hours writing JSON encoding code - just wrap it instead. Using Wrap is as easy as calling wrap() on any instance of a class or struct that you wish to encode. It automatically encodes all of your type’s properties, including nested objects, collections, enums and more. It also provides a suite of simple but powerful customization APIs that enables you to use it on any model setup with ease.

A fast & lightweight XML/HTML parser in Swift that makes your life easier. Fuzi is based on a Swift port of Mattt Thompson's Ono(斧), using most of its low-level implementations with moderate class & interface redesign following standard Swift conventions, along with several bug fixes. Extremely performant document parsing and traversal, powered by libxml2. Support for both XPath and CSS queries. Automatic conversion of date and number values. Correct, common-sense handling of XML namespaces for elements and attributes. Ability to load HTML and XML documents from either String or NSData or [CChar]. Comprehensive test suite. Full documentation. Simple, modern API following standard Swift conventions, no more return types like AnyObject! that cause unnecessary type casts.

HandyJSON is a framework written in Swift which makes converting model objects( pure classes/structs ) to and from JSON easy on iOS. Compared with others, the most significant feature of HandyJSON is that it does not require the objects inherit from NSObject(not using KVC but reflection), nor implements a 'mapping' function(writing value to memory directly to achieve property assignment). HandyJSON is totally dependent on the memory layout rules inferred from Swift runtime code. We are watching it and will follow every bit if it changes. To support deserialization from JSON, a class/struct needs to conform to 'HandyJSON' protocol. It's truly protocol, not some class inherited from NSObject. For struct, since the compiler provides a default empty initializer, we use it for free. HandyJSON supports deserialization from the designated path of JSON.

iOS Text View (UIView) that Properly Displays LaTeX, HTML, Markdown, and YouTube/Vimeo links. In order for the RichTextView to handle the various use cases it might encounter, the input string needs to be formatted.

Swift is strictly specific about types. But even if explicit typing is good for avoiding making mistakes, it becomes painful when we're dealing with JSON and other aspects that are, by definition, implicit about types. SwiftyJSON, however, facilitates the use of JSON data in Swift.
