The VIP architectural pattern is one of the least known patterns in iOS development compared to MVVM, MVC or VIPER. You’re reading that correctly; VIP isn’t VIPER.

They’re different implementations of the Uncle Bob’s Clean Architecture pattern.

VIPER’s creators wanted to name it VIP. But they didn’t want developers to read it as Very Important Architecture, so they named it VIPER instead.

What does VIP stand for then? View – Interactor – Presenter.

The VIP architecture for writing clean Swift code was introduced by Raymond Law. He created a clean-swift website where you can read about how to use VIP pattern in UIKit.

In this tutorial, you’ll build an ice cream maker app called Scoops&Scones using the VIP architecture in SwiftUI. The UI is already set up, so you can focus on building the logic and making the app work.
