This is Not just Another Swift JSON Package. This is the Swift JSON Package.
When you are transforming directly to models this framework is faster than Foundation.JSONSerialization.
Time to Parse and initialize a struct from a sample 432KB JSON file.

Tests run on Darwin (Linux Foundation is even slower) built with -Ounchecked
Type safety can get you a long way, lets see how you can use it for your applications.
enum Currency: String { case AUD, EUR, GBP, USD }
struct Money {
var minorUnits: Int
var currency: Currency
}
struct Person {
var name: String
var age: Int
var accountBalances: [Money]
var petName: String?
}
extension Money: JSONConvertible {
func encoded() -> JSON {
return
[
"minorUnits": minorUnits,
"currencyCode": currency.encoded()
]
}
init(json: JSON) throws {
self.minorUnits = try json.get("minorUnits")
self.currency = try json.get("currencyCode")
}
}
extension Person: JSONConvertible {
func encoded() -> JSON {
return
[
"name": name,
"age": age,
"accountBalances": accountBalances.encoded()
]
}
init(json: JSON) throws {
self.name = try json.get("name")
self.age = try json.get("age")
self.accountBalances = try json.get("accountBalances")
self.petName = try json.get("petName")
}
}
