Dependency injector Swift compatible with ObjectMapper



To install DependencyInjector+ObjectMapper with CocoaPods, add the following lines to your Podfile.

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

pod 'DependencyInjectorObjectMapper'


Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate DependencyInjector+ObjectMapper into your Xcode project using Carthage, specify it in your Cartfile:

github 'Digipolitan/dependency-injector-object-mapper' ~> 1.0

Run carthage update to build the framework and drag the built DependencyInjectorObjectMapper.framework into your Xcode project.

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding DependencyInjector+ObjectMapper as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/Digipolitan/dependency-injector-object-mapper.git", from: "1.0.0")

How to use ?

First you must create your models conforms to BaseMappable protocol

public protocol User: BaseMappable {
    var id: String { get set }
    var created: Date? { get set }
    var address: Address { get set }

public protocol Address: BaseMappable {
    var street: String { get set }
    var zipCode: String { get set }
    var country: String { get set }

After that, create the real implementation conforms to Mappable protocol foreach models

class UserModel: User, Mappable {
    public var id: String
    public var created: Date?
    public var address: Address

    public init(id: String, address: Address) {
        self.id = id
        self.address = address

    public convenience required init?(map: Map) {
            let id: String = try? map.value("id"),
            let address: Address = try? map.injectedValue("address", type: Address.self) else {
                return nil
        self.init(id: id, address: address)

    public func mapping(map: Map) {
        self.id >>> map["id"]
        self.created <- (map["createdAt"], DateTransform())
        self.address >>> map.inject("address", type: Address.self)

class AddressModel: Address, Mappable {
    public var street: String
    public var zipCode: String
    public var country: String

    public init(street: String, zipCode: String, country: String) {
        self.street = street
        self.zipCode = zipCode
        self.country = country

    public convenience required init?(map: Map) {
        guard let street: String = try? map.value("street"), let zipCode: String = try? map.value("zipCode"), let country: String = try? map.value("country") else {
            return nil
        self.init(street: street, zipCode: zipCode, country: country)

    public func mapping(map: Map) {
        self.street >>> map["street"]
        self.zipCode >>> map["zipCode"]
        self.country >>> map["country"]
  • For nonnull property set the value inside the initializer

  • To inject a custom implementation use map.injectedValue during the init process, or map.inject in the mapping function

After that, you must register implementation inside a module and push the module inside an injector

class DefaultModule: Module {

    override init() {
Injector.default.register(module: DefaultModule(), with: "default")

Finally, inject the User model as follow

let user = try? Injector.default.inject(User.self, arguments: [
    "id": "1",
    "address": [
        "street": "abc",
        "zipCode": "75116",
        "country": "France"
