SwiftUI – How to pass EnvironmentObject into View Model?

You can do it like this:

struct YourView: View {
  @EnvironmentObject var settings: UserSettings

  @ObservedObject var viewModel = YourViewModel()

  var body: some View {
    VStack {
      Text("Hello")
    }
    .onAppear {
      self.viewModel.setup(self.settings)
    }
  }
}

For the ViewModel:

class YourViewModel: ObservableObject {
  
  var settings: UserSettings?
  
  func setup(_ settings: UserSettings) {  
    self.settings = settings
  }
}
