๐Ÿ’‰ DependencyInjection

A library to inject your dependencies via property wrappers

Github Swift Swift Package Manager codecov

๐ŸŒŸ Features

DependencyInjection allows you to define the dependencies of your app. It exposes a property wrapper to make easier the injection in your instances. Every instance can be resolved at three different levels:

  • instance: Resolves a unique instance across the entire app
  • shared: Resolves the instance and allows it to be reused if it is needed on another object
  • global: The instance will act as a singleton

๐Ÿ— Usage

There are two separate steps when using DependencyInjection

Register dependecies

Starting on version 1.0.0 DependencyInjection makes use of Obj-C runtime to search the injection modules across the final module once the first injection is requested.

In order to declare your module you have to declare a class that conforms to ModuleContract and call it Module. Once this is done, DependencyInjection will consider it when building the injection structure as explained before.

final class Module: ModuleContract {
    static func get() {
        instance(TypeAContract.self, TypeA.self)
        shared(TypeBContract.self, TypeB.self)
        global(TypeCContract.self, TypeC.self)

Injecting instance

To inject an instance you can just use the property wrapper:

protocol Definition: Injectable {}
class Implementation: Definition {}

@Injected var instance: Definition // It will be Implementation

๐Ÿ›  Compatibility

This library can be used on iOS, macOS, iPadOS, watchOS and tvOS as it only relies on Foundation framework

โš™๏ธ Installation

You can use the Swift Package Manager by declaring DependencyInjection as a dependency in your Package.swift file:

.package(url: "https://github.com/AlbGarciam/DependencyInjection", from: "0.1.0")

DependencyInjection exposes 2 versions of the library, a static and a dynamic version.
