Arrow

Arrow is an elegant JSON parsing library in Swift.

It allows to parse JSON and map it to custom model classes with help of an <-- operator:

identifier <-- json["id"]
name <-- json["name"]
stats <-- json["stats"]

Example:

Swift model

struct Profile {
    var identifier = 0
    var name = ""
    var link: NSURL?
    var weekday: WeekDay = .Monday
    var stats = Stats()
    var phoneNumbers = [PhoneNumber]()
}

JSON file

{
    "id": 15678,
    "name": "John Doe",
    "link": "https://apple.com/steve",
    "weekdayInt" : 3,
    "stats": {
        "numberOfFriends": 163,
        "numberOfFans": 10987
    },
    "phoneNumbers": [{
                     "label": "house",
                     "number": "9809876545"
                     }, {
                     "label": "cell",
                     "number": "0908070656"
                     }, {
                     "label": "work",
                     "number": "0916570656"
    }]
}

Mapping

extension Profile: ArrowParsable {
    mutating func deserialize(json: JSON) {
        identifier <-- json["id"]
        link <-- json["link"]
        name <-- json["name"]
        weekday <-- json["weekdayInt"]
        stats <- json["stats"]
        phoneNumbers <-- json["phoneNumbers"]
    }
}

Usage

let profile = Profile()
profile.deserialize(json)
