SwiftUI - how to get @EnvironmentObject data inside @ObservableObject

Question

Is it possible to use a @EnvironmentObject inside an ObservableObject?

It is giving me an error:

Fatal error: No ObservableObject of type EntryViewModel found. A View.environmentObject(_:) for EntryViewModel may be missing as an ancestor of this view.: file SwiftUI, line 0

I know the @EnvironmentObject is good because I use it other places.

If not, how can I get the information?

class ResultsViewModel: ObservableObject {
    @EnvironmentObject var entry: EntryViewModel
    ...
}

Thank you.

No, it is not. @EnvironmentObject can be used in View only.

A possible solution is to pass it in init:

class ResultsViewModel: ObservableObject {
    var entry: EntryViewModel

    init(entry: EntryViewModel) {
        self.entry = entry
    }
}

Another solution may be to use a singleton or (maybe the best) dependency injection.
