SOLVED: UltimatePortfolio App: First steps in UI: FetchRequest in View

Forums > Articles

Dear all,

I have an app architecture related question.

According to MVVM design, a View should not directly access the Model. Only via a ViewModel access to the model should be possible.

In the UltimatePortfolio App, fetchRequest in the view is used to access objects in CoreData. So in my understanding, a view is accessing the model directly, either with the property wrapper @FetchRequest or via the initializer. Also, it creates a tight coupling between the view and CoreData, which may not be preferred.

Would that design choice not be in contrast to the MVVM design?

Maybe I'm getting something wrong or missed something (maybe the UltimatePortfolio App is not aiming for a MVVM design or similar, or the mentioned approach is indeed in accordance with MVVM design).

Any help is greatly appreciated.

Cheers

Tobias

I don't believe there was mention that the Ultimate Portfolio app was specifically aiming to conform to the MVVM architecture paradigm.

@cgaafary Thank you for the quick response and the clarification!

In case someone has a good resource which covers MVVM and core data (other than the one I already provided in my original post), I'd greatly appreciate it.
