ModelMapper

An abstraction for mapping models, write a mapper once, use everywhere.

It's a best practice, like in clean architecture, to create a model for reach domain, for example a DTO for network response, Entity for database, and so on. But mapping each model is something painful as you have to map objects, arrays and deal with optionals. Here's where ModelMapper shines, just create a single mapper for the object and use it to map objects, Arrays, and optional Arrays.

Usage

import ModelsMapper

// declare Mapper
struct UserDtoMapper: Mapper {
    typealias I = UserDto
    typealias O = User
    
    func map(_ input: UserDto) -> User {
        User(name: input.name, email: input.email)
    }
}

// map UserDto to User
let user: User = UserDtoMapper().map(userDto)

// map [UserDto] to [User]
let input: [UserDto] = [userDto, userDto]
let users: [User] = ListMapper(UserDtoMapper()).map(input)

// map [UserDto]? to [User]
let input: [UserDto]? = nil
let users: [User] = OptionalInputListMapper(UserDtoMapper()).map(input)

// map [UserDto] to [User]?
let input: [UserDto] = []
let users: [User]? = OptionalOutputListMapper(UserDtoMapper()).map(input)  

// map [UserDto]? to [User]?
let input: [UserDto]? = nil
let users: [User]? = OptionalListMapper(UserDtoMapper()).map(input)  

Installation

Swift Package Manager

To integrate using Apple's Swift package manager, add the following as a dependency to your Package.swift:

.package(url: "https://github.com/ShabanKamell/ModelMapper.git", .upToNextMajor(from: "0.1.0"))

and then specify "ModelMapper" as a dependency of the Target in which you wish to use ModelMapper. Here's an example PackageDescription:

// swift-tools-version:5.0
import PackageDescription

let package = Package(
    name: "MyPackage",
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]),
    ],
    dependencies: [
        .package(url: "https://github.com/ShabanKamell/ModelMapper-Swift.git", .upToNextMajor(from: "0.1.0"))
    ],
    targets: [
        .target(
            name: "MyPackage",
            dependencies: ["ModelMapper"])
    ]
)

Don't forget to add import ModelMapper to use the framework.

Accio

Accio is a dependency manager based on SwiftPM which can build frameworks for iOS/macOS/tvOS/watchOS. Therefore the integration steps of ModelMapper are exactly the same as described above. Once your Package.swift file is configured, run accio update instead of swift package update.

Don't forget to add import ModelMapper to use the framework.

CocoaPods

For ModelMapper, use the following entry in your Podfile:

pod 'ModelsMapper', '~> 0.1.0'

Then run pod install.

Don't forget to add import ModelsMapper to use the framework.

Carthage

Carthage users can point to this repository and use generated ModelMapper framework.

Make the following entry in your Cartfile:

github "ShabanKamell/ModelMapper-Swift" ~> 0.1.0

Then run carthage update.

If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained over at Carthage.
