A practical JSON parsing library for Swift. It provides a fully typed and validated API surface for working with JSON, including the ability to base64 items with your JSON.
All of the JSON APIs return back of Optional<T>. This allows for easier use for deep indexing. In addition, there is an Optional<JSValue> wrapper for all indexers and accessors which removes all of the ? jumping that is normally required.
Also, there is a functional API set for the library as well. For an in-depth overview of that, see: Functional JSON.
Initializing a JSON value
let json : JSON = [ "stat": "ok", "blogs": [ "blog": [ [ "id" : 73, "name" : "Bloxus test", "needspassword" : true, "url" : "http://remote.bloxus.com/" ], [ "id" : 74, "name" : "Manila Test", "needspassword" : false, "url" : "http://flickrtest1.userland.com/" ] ] ] ]Retrieve data from JSON
if let stat = json["stat"].string { println("stat = '\(stat)'") // prints: stat = 'ok' }Retrieve error information from a missing key lookup
let stat = json["stats"] if let value = stat.string { println("stat = '\(value)'") } else if let error = stat.error { println("code: \(error.code), domain: '\(error.domain)', info: '\(error.userInfo[LocalizedDescriptionKey]!)'") // prints: code: 6, domain: 'com.kiadstudios.json.error', info: 'There is no value stored with key: 'stats'.' }Iterate over the contents of an array
if let blogs = json["blogs"]["blog"].array { for blog in blogs { println("blog: \(blog)") } }See JSValueTests.Usage.swift for more usage samples.
