When developing with Cocoa/UIKit, the most common used architecture is MVC.

• Model-View-Controller

What is the architecture when using SwiftUI? Someone says it is MVVM. Someone says it is MV, MVC without C. I would like say it would be M-VC, Model with View and Controller.

• Stop using MVVM for SwiftUI

M-VC

We want every element to be simple. For MV architecture, the View is too heavy for me. For M-VC, we want the View as simple as possible. The extra parts we think it to be Controller.

Split View into small Views

For a SwiftUI View, when one of the @State properties changed, all @State properties in the same view will be updated. If this is overhead, you can split those @State properties to another view, that will reduce CPU usage and speed up your app.
