SwiftMVCR (Model, View, Controller, Router)

SwiftMVCR is an sample iOS App written in Swift using the MVCR architecture. (Model, View, Controller, Router)

Sample App

Architecture

Run Sample

1. Clone this repository.

   git clone [email protected]:yokurin/Swift-MVCR-iOS.git
   

2. Open SwiftMVCR.xcodeproj in Xcode.

3. Run

Description

MVCR means Model, View, Controller, Router.
You can easy to know transitions of app. But, Not testable Architecture

Model

Model must implement Modelable.

protocol Modelable {
    // nop
}

Example

final class Model: Modelable {
    ...
}

View (including UIViewController)

View must implement Viewable. Viewable has Default Extension.
※ View is not just View like UIView etc in this case.

protocol Viewable: AnyObject {
    func push(_ vc: UIViewController, animated: Bool)
    func present(_ vc: UIViewController, animated: Bool)
    func pop(animated: Bool)
    func dismiss(animated: Bool)
    func dismiss(animated: Bool, completion: @escaping (() -> Void))
}

extension Viewable where Self: UIViewController {

    func push(_ vc: UIViewController, animated: Bool) {
        self.navigationController?.pushViewController(vc, animated: animated)
    }

    func present(_ vc: UIViewController, animated: Bool) {
        self.present(vc, animated: animated, completion: nil)
    }

    func pop(animated: Bool) {
        self.navigationController?.popViewController(animated: animated)
    }

    func dismiss(animated: Bool) {
        self.dismiss(animated: animated, completion: nil)
    }

    func dismiss(animated: Bool, completion: @escaping (() -> Void)) {
        self.dismiss(animated: animated, completion: completion)
    }
}

Example

extension ViewController: Viewable {}

Controller (including UIViewController)

Controller must implement Controllerable.

protocol Controllerable {
    associatedtype M: Modelable
    associatedtype R: Routerable
    var model: M! { get }
    var router: R! { get }
}

Example

final class ViewController: UIViewController, Controllerable {
    
    ...
    
    static func configure(entryModel: EntryModel) -> ViewController {
        let controller = ViewController()
        controller.router = RouterOutput(controller)
        controller.model = Model(entryModel: entryModel)
        return controller
    }
    
    private(set) var model: Model!
    private(set) var router: RouterOutput!
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    ...
}

UIViewController has roles that View and Controller. But, its ok.

Router

Router must implement Routerable.

protocol Routerable {
    var view: Viewable! { get }

    func dismiss(animated: Bool)
    func dismiss(animated: Bool, completion: @escaping (() -> Void))
    func pop(animated: Bool)
}

extension Routerable {
    func dismiss(animated: Bool) {
        view.dismiss(animated: animated)
    }

    func dismiss(animated: Bool, completion: @escaping (() -> Void)) {
        view.dismiss(animated: animated, _completion: completion)
    }

    func pop(animated: Bool) {
        view.pop(animated: animated)
    }
}

Example

struct EntryModel {}

final class RouterInput {
    func push(from: Viewable, entryModel: EntryModel) {
        let controller = ViewController.configure(entryModel: entryModel)
        from.push(controller, animated: true)
    }

    func present(from: Viewable, entryModel: EntryModel) {
        let controller = ViewController.configure(entryModel: entryModel)
        from.present(controller, animated: true)
    }
}

final class RouterOutput: Routerable {

    weak private(set) var view: Viewable!

    init(_ view: Viewable) {
        self.view = view
    }

    func transitionToOther(entryModel: EntryModel) {
        OtherRouterInput().push(from: view, entryModel: entryModel)
    }
}
