Serializable is a framework made for creating model objects or structs that can be easily serialized and deserialized from/to JSON. It’s implemented using protocol extensions, which makes it easily expandable.

It’s easily expandable and handles all common data types used when consuming a REST API, as well as recursive parsing of custom objects.

It’s designed to be used together with our helper app, the ModelBoiler Model Boiler, making model creation a breeze.

The Serializable framework uses static typing, exhibiting superior performance compared to frameworks using reflection and eliminates boilerplate code.

Why Serializable?

There are plenty of other Encoding and Decoding frameworks available. Why should you use Serializable?

  • Performance. Serializable is fast, up to 4x faster than similar frameworks
  • Features. Serializable can parse anything you throw at it. Nested objects, Enums, NSURL, UIColor, you name it!
  • ModelBoiler Model Boiler. Every framework of this kind requires tedious boilerplate code that takes forever to write, ModelBoiler Model Boiler generates it for you instantly.

📝 Requirements

  • iOS 8.0+
  • Swift 2.0+

📦 Installation


github "nodes-ios/Serializable" 


pod 'Serializable', '~> 0.1.0'

Swift Package Manager

To use Serializable as a Swift Package Manager package just add the following to your Package.swift file.

import PackageDescription

let package = Package(
    name: "YourPackage",
    dependencies: [
        .Package(url: "", majorVersion: 0)

NOTE: This doesn’t currently work as SPM doens’t support UIKit, but once it will we will already be supporting it! :)

🔧 Setup

We highly recommend you use our ModelBoiler Model Boiler to assist with generating the code needed to conform to Serializable. Instructions for installation and usage can be found at the Model Boiler github repository.

💻 Usage

Getting started

Serializable supports Primitive types, Enum, NSURL, NSDate, UIColor, other Serializables, and Arrays of all of the aforementioned types. Your variable declarations can have a default value or be optional.

Primitive types do not need to have an explicit type, if Swift is able to infer it normally. var name: String = "" works just as well as var name = "". Optionals will of course need an explicit type.

Note: Enums you create must conform to RawRepresentable, meaning they must have an explicit type. Otherwise, the parser won’t know what to do with the incoming data it receives.

Create your model struct or class:

struct Foo {
    var id = 0
    var name = ""
    var address: String? 

NOTE: Classes must be marked final

Add the required methods for Encodable and Decodable:

extension Foo: Serializable {
    init(dictionary: NSDictionary?) {
        id      <== (self, dictionary, "id")
        name    <== (self, dictionary, "name")
        address <== (self, dictionary, "address")

    func encodableRepresentation() -> NSCoding {
        let dict = NSMutableDictionary()
        (dict, "id")      <== id
        (dict, "name")    <== name
        (dict, "address") <== address
        return dict

And thats it! If you’re using the ModelBoiler Model Boiler, this extension will be generated for you, so that you don’t need to type it all out for every model you have.

Using Serializable models

New instances of your model can be created with a dictionary, e.g. from parsed JSON.

let dictionary = try NSJSONSerialization.JSONObjectWithData(someData, options: .AllowFragments) as? NSDictionary
let newModel = Foo(dictionary: dictionary)

You can generate a dictionary version of your model by calling encodableRepresentation():

let encodedDictionary = newModel.encodableRepresentation()

More complex examples

In this example, we have two models, Student and School.

struct Student {
    enum Gender: String {
        case Male = "male"
        case Female = "female"
        case Unspecified = "unspecified"

    var name = ""
    var age: Int = 0
    var gender: Gender?

struct School {
    enum Sport: Int {
        case Football
        case Basketball
        case Tennis
        case Swimming

    var name = ""
    var location = ""
    var website: NSURL?
    var students: [Student] = []
    var sports: [Sport]?

You can get as complicated as you like, and the syntax will always remain the same. The extensions will be:

extension Student: Serializable {
    init(dictionary: NSDictionary?) {
        name   <== (self, dictionary, "name")
        age    <== (self, dictionary, "age")
        gender <== (self, dictionary, "gender")

    func encodableRepresentation() -> NSCoding {
        let dict = NSMutableDictionary()
        (dict, "name")   <== name
        (dict, "age")    <== age
        (dict, "gender") <== gender
        return dict

extension School: Serializable {
    init(dictionary: NSDictionary?) {
        name     <== (self, dictionary, "name")
        location <== (self, dictionary, "location")
        website  <== (self, dictionary, "website")
        students <== (self, dictionary, "students")
        sports   <== (self, dictionary, "sports")

    func encodableRepresentation() -> NSCoding {
        let dict = NSMutableDictionary()
        (dict, "name")     <== name
        (dict, "location") <== location
        (dict, "website")  <== website
        (dict, "students") <== students
        (dict, "sports")   <== sports
        return dict

Again, the ModelBoiler Model Boiler generates all of this code for you in less than a second!
