This also worked fine for me,

private func createParamDownloadEntityFrom(dictionary: [String: AnyObject]) -> NSManagedObject? {
    let context = CoreDataStack.sharedInstance.persistentContainer.viewContext

    if let paramEntity = NSEntityDescription.insertNewObject(forEntityName: “ParamDwonload”, into: context) as? ParamDownload {
        paramEntity.code = dictionary[“code”] as? String
        paramEntity.desc = dictionary[“desc”] as? String
        let innData = dictionary["iinData"] as! NSArray


        for i in 0..<(innData.count-1) {

            if let nameEntity = NSEntityDescription.insertNewObject(forEntityName: Name
                , into: context) as? Name {

                if let val = innData[i] as? [String: Any] {
                    nameEntity.bankName = val[“name"] as? String
                    nameEntity.iin = val[“iin"] as? String
                    if let isOn = Int16(val[“isOn"] as! String) {
                        nameEntity.isOnus = isOn
                    }
                    paramEntity.addToNames(nameEntity)
                }

            }
        }
        return paramEntity
    }
