I have this view.

struct AView: View {
    @Environment(\.managedObjectContext) private var viewContext
    @State var timestamp: Date
    @State private var obj: MyObject
    
    init(date: Date)
    {
        // this is fine
        _timestamp = State(initialValue: date)
        // this gives an error
        _obj = State(initialValue: MyObject(context: viewContext))
    }

    var body: some View {
        ...
    }
}

I need to initialize the object obj, which must be initialized with an NSManagedObjectContext, inside of the init function. However, when I try to use the code above, I get this error

Variable 'self.obj' used before being initialized

How do I initalize a variable in the init function that depends on an NSManagedObjectContext?
