SOLVED: BookWorm - How do I "inject a managed object context" into the previews struct?

Forums > 100 Days of SwiftUI

This is what I thought made sense, but the compiler tells me the datacontroller instance cannot be used in COntentView_Previews

struct ContentView_Previews: PreviewProvider {
    @StateObject private var dataController = DataController()
    static var previews: some View {
        ContentView()
            .environment(\.managedObjectContext, dataController.container.viewContext)
    }
}
