Great explanation of MVVM! I’ve been implementing this model in my projects thanks to you.

An alternate approach, building on your approach, where we make the ViewModels independent of service calls and business logic, for even better separation of concerns:

Create a single AppCoordinator in AppDelegate, and keep a strong reference to it.
The AppCoordinator is responsible for Service calls, persistence, caches, managing and injecting dependencies, business logic etc.
Coordinators are also responsible for creating ViewModels (from Models), and for passing them down to View hierarchies.
The ViewModels are very simple; they don't perform any Service calls. Instead, they can have bindings to Coordinator properties, and will interpret those bindings to produce simple values usable by Views.
This approach removes a lot of responsibility from the ViewModel.
Child Coordinators can be used to further separate out the work. e.g. LoginCoordinator, SettingsScreenCoordinator, GameScreenCoordinator, etc.

This Coordinator pattern is almost identical for non-SwiftUI apps as well. (RxSwift can be used for binding on < iOS13 targets.)
Cheers.

I’ve a question about the udemy course. Do you update the past videos when Apple deprecate something in a recent beta?
