Problem using @Environment variable in SwiftUI constructor

Question

I'm using a core data child context to separate temporary entities from my main context, but when I pass in the main context as an environment variable, I don't have access to it in order to initialize the child context and get a 'self' used before all stored properties are initialized error

Any suggestions?

struct CreatePlayerView: View {
    @State private var newPlayer: PlayerEntity
    @Environment(\.managedObjectContext) private var managedObjectContext

    private let childManagedObjectContext: NSManagedObjectContext

    init() {
        childManagedObjectContext = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType)

        \\ 'self' used before all stored properties are initialized
        childManagedObjectContext.parent = managedObjectContext

        newPlayer = PlayerEntity(context: childManagedObjectContext)
    }

    var body: some View {
        EditPlayerViewDetail(
            player: $newPlayer,
            onDone: { player in
                try? childManagedObjectContext.save()
            }
        )
    }
}
