NSBatchInsertRequest

It seems to be missing. This sample code is from 8:30 from the "Making Apps with Core Data" and throws an error when compiling "Use of unresolved identifier". Fingers crossed for inclusion in beta 3 😟

taskContext.perform {
            let insertRequest = NSBatchInsertRequest(entity: MediaCollection.entity(), objects: objectDicts)
            let insertResult = try? taskContext.execute(insertRequest) as! NSBAtchInsertRequest
            let success = insertResult as! Bool
        }

Hi

I try to use the "NSBatchInsertRequest". but the insertResult is nil, and my CoreData is empty

I use the viewContext of the "NSPersistentCloudKitContainer".

let container = NSPersistentCloudKitContainer(name: "CoreDataPerformance")
                    container.loadPersistentStores(completionHandler: { (storeDescription, error) in
                        if let error = error as NSError? {
                            fatalError("Unresolved error \(error), \(error.userInfo)")
                        }
                    })
                   
                    try container.viewContext.setQueryGenerationFrom(.current)
                   
                    let moc = container.viewContext
                    moc.automaticallyMergesChangesFromParent = true
                    moc.perform {
                        let insertRequest = NSBatchInsertRequest(entity: Client.entity(), objects: clients)
                        let insertResult = try? moc.execute(insertRequest) as? NSBatchInsertRequest
                        if let success = insertResult as? Bool {
                            print("RESULT: \(success)")
                        }
                    }

This is the error I receive in the console.

Any ideas ?
