# Injectable

Dependency Injection for Swift.

The dependency injection pattern leads to code that's modular and testable, and Guice makes it easy to write. 

[Google Guice](https://github.com/google/guice/wiki/Motivation)

## Installation

```

pod 'Injectable'

```

## Usage

``` swift

// ViewController.swift

class ViewController: UIViewController {

    @IBAction func show(_ sender: Any) {

        let viewController: InjectableViewController = InjectableViewController(with: .init(color: .green))

        self.present(viewController, animated: true, completion: nil)

    }

    

    override func viewDidLoad() {

        super.viewDidLoad()

    }

}

```

``` swift

// InjectableViewController.swift

protocol Colorable: Injectable {

    init(with dependency: Dependency)

}

class InjectableViewController: UIViewController, Colorable {

    required init(with dependency: InjectableViewController.Dependency) {

        super.init(nibName: nil, bundle: nil)

        self.inject(dependency)

    }

    required init?(coder aDecoder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }

    struct Dependency {

        var color: UIColor

    }

    func inject(_ dependency: InjectableViewController.Dependency) {

        self.view.backgroundColor = dependency.color

    }

}

```
