Dependency Injection for Swift

Injectable

Dependency Injection for Swift.

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

Installation

pod 'Injectable'

Usage

// 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()
    }
}

// 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
    }
}

injectable's Issues

Request: Release of Cocoapods Name

Hi @1amageek, I'm about to open source a new Swift Dependency Injection framework. I wanted to name it "Injectable", but this library already owns that name in the pod trunk. Since this library hasn't been updated or used in 3 years, I was hoping you would release the name to me. Would you be willing to transfer ownership of the pod in the Cocoapods trunk to me, so that I can release my library with that name? I'd really appreciate it.
