in this code below i think there is an error: batchDeleteRequest1 in the text of video 2 called Designing a great model: I think we have to remove the 1

private func delete(_ fetchRequest: NSFetchRequest<NSFetchRequestResult>) {
    let batchDeleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)
    batchDeleteRequest.resultType = .resultTypeObjectIDs

    if let delete = try? container.viewContext.execute(batchDeleteRequest1) as? NSBatchDeleteResult {
        let changes = [NSDeletedObjectsKey: delete.result as? [NSManagedObjectID] ?? []]
        NSManagedObjectContext.mergeChanges(fromRemoteContextSave: changes, into: [container.viewContext])
    }
}
