Simple decoding of JSON to Swift structs/classes

SwiftDecodable

Simple decoding of JSON to Swift structs/classes.

Usage

Allow a struct or class to be decoded by making it conform to the Decodable protocol.

struct Person {
    let name: String
    let age: Int
}

extension Person: Decodable {
    init(decoder: Decoder) throws {
        self.name = try decoder.value(forKey: "name")
        self.age = try decoder.value(forKey: "age")
    }
}

Then decode it with some JSON:

let json: JSON = [
    "name": "John Doe",
    "age": 35
]
let person = Person(json: json)

Or straight from some JSON data:

let data: NSData = ...
let person = Person(data: data)
