VIPER-Demo

This is the simplest approach to show VIPER pattern. Demonstrates switching between two Views.
Focus on references between objects(Presenter, View, Router) and show how everything initialise, connected and de-initialise.

Usage:

• Protocols
• Delegates

Features:

• Once the view is “loaded”, the configurator creates Presenter, Interactor, Router.
• Interactor does nothing in this demo (there is no logic and data management)
• Once you press the button -> Presenter listens to View and asks Router to do his job.
• The new screen appears. In console you can monitor creation, connections.
• Once you close the View, console will print all “de-init”.

Console output:
openButtonClicked
SomeRouter was asked to showSecond()
Configurator init
Presenter init(viewcontroller:)
Presenter.viewcontroller - weak -> viewcontroller
Interactor init(presenter:)
Interactor.presenter - weak -> presenter
Router init(viewController:)
Router.viewController - weak -> viewController
ViewController -> presenter
Presenter.router -> router
Presenter.interactor -> interactor
Presenter closeClicked()
SecondViewController viewWillDisappear(:)
SecondViewController viewDidDisappear(:)
Presenter deinit
Interactor deinit
Router deinit
Configurator de-init
