JASON is a faster JSON
deserializer written in Swift.
JASON is the best framework we found to manage JSON at Swapcard. This is by far the fastest and
the most convenient out there, it made our code clearer and improved the global performance
of the app when dealing with large amount of data.
Gautier Gédoux, lead iOS developer at Swapcard

Usage
Initialization
let json = JSON(anything) // where `anything` is `AnyObject?`
If you're using Alamofire
, include JASON+Alamofire.swift
in your project for even more awesomeness:
Alamofire.request(.GET, peopleURL).responseJASON { response in
if let json = response.result.value {
let people = json.map(Person.init)
print("people: \(people)")
}
}
If you're using Moya
, check out Moya-JASON
!
Parsing
Use subscripts to parse the JSON
object:
json["people"][0]["name"]
// Or with a path:
json[path: "people", 0, "name"]
Type casting
Cast JSON
value to its appropriate type by using the computed property json.<type>
:
let name = json["name"].string // the name as String?
The non-optional variant json.<type>Value
will return a default value if not present/convertible:
let name = json["wrong"].stringValue // the name will be ""
You can also access the internal value as AnyObject?
if you want to cast it yourself:
let something = json["something"].object
See the References section for the full list of properties.
JSONKey
:
This idea is stolen from
SwiftyUserDefaults
by Radek Pietruszewski (GitHub, Twitter, Blog). I can't recommend enough to read his article about it! :boom: Statically-typed NSUserDefaults :boom:
Define and use your JSONKey
as follow:
// With a int key:
let personKey = JSONKey<JSON>(0)
let personJSON = peopleJSON[personKey]
// With a string key:
let nameKey = JSONKey<String>("name")
let name = personJSON[nameKey]
// With a path:
let twitterURLKey = JSONKey<NSURL?>(path: 0, "twitter")
let twitterURL = peopleJSON[twitterURLKey]
You might find more convenient to extend JSONKeys
as shown in the Example section.
See the References section for the full list of JSONKey
types.
Third-party libraries:
- DroidsOnRoids/Moya-JASON JASON bindings for Moya.
Example
This example uses the Dribbble API (docs). An example of the server response can be found in
Tests/Supporting Files/shots.json
- Step 1: Extend
JSONKeys
to define yourJSONKey
JSON.dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
extension JSONKeys {
static let id = JSONKey<Int>("id")
static let createdAt = JSONKey<NSDate?>("created_at")
static let updatedAt = JSONKey<NSDate?>("updated_at")
static let title = JSONKey<String>("title")
static let normalImageURL = JSONKey<NSURL?>(path: "images", "normal")
static let hidpiImageURL = JSONKey<NSURL?>(path: "images", "hidpi")
static let user = JSONKey<JSON>("user")
static let name = JSONKey<String>("name")
}
- Step 2: Create the
Shot
andUser
models
struct Shot {
let id: Int
let title: String
let normalImageURL: NSURL
var hidpiImageURL: NSURL?
let createdAt: NSDate
let updatedAt: NSDate
let user: User
init(_ json: JSON) {
id = json[.id]
title = json[.title]
normalImageURL = json[.normalImageURL]!
hidpiImageURL = json[.hidpiImageURL]
createdAt = json[.createdAt]!
updatedAt = json[.updatedAt]!
user = User(json[.user])
}
}
struct User {
let id: Int
let name: String
let createdAt: NSDate
let updatedAt: NSDate
init(_ json: JSON) {
id = json[.id]
name = json[.name]
createdAt = json[.createdAt]!
updatedAt = json[.updatedAt]!
}
}
- Step 3: Use the
JASON+Alamofire.swift
extension to fetch the shots
Alamofire.request(.GET, shotsURL).responseJASON { response in
if let json = response.result.value {
let shots = json.map(Shot.init)
}
}
