Calling Model from another model

[CalStark]

Super interesting problem. I’ve spent some time thinking about this too, you can check it out right here:

ViewModels interoperability with MVVM Architecture | SwiftUI

Hi, I’ve been encountering use cases where I can’t help but want to make my ViewModels communicate with each other. Imagine an app with several ViewModels as EnvironmentObjects, where each handles rather extensive business logics about different things. As an example and for the sake of discussion, imagine there’s first a WeatherViewModel that handles business logic about weather data, and second a StoreViewModel that handles business logic notably about the frequency of visits to a store. Sa…

I’m guessing both of your ViewModels are injected somewhere in the view hierarchy as environment objects.

The thing is, your TestModel2 does not have access to your TestModel1 at the moment.

   func printTestModel1() {
        let testModel1 = TestModel()
        
        print("testModel.testModel.element:\(testModel1.test.element)")
    }

This method in TestModel2 is instantiating a new TestModel1. NOT accessing the TestModel1 instance you injected somewhere in the view hierarchy.
