Где я должен разместить код расширения Callkit Reload Extension в моем проекте IOS

Я делаю приложение, подобное TrueCaller. Сначала я могу заблокировать номер, но всякий раз, когда я обновляю/добавляю новый номер, мне нужно вручную отключить и включить плагин каталога вызовов в Настройки -> Телефон -> Блокировка вызовов и идентификация, чтобы получить список обновлено. Я видел много ответов на StackOverflow, где люди говорят, что нужно вызвать CXCallDirectoryManager.reloadExtension, чтобы перезагрузить расширение через код. Но я не знаю, где написать этот код или откуда мне вызвать это reloadExtension из моего проекта.

Обновление -1 Вот как я подошел. Ниже приведен мой код контроллера просмотра.

@IBAction func add(_ sender: Any) {
    //let defaults = UserDefaults.standard
    let userDefaults = UserDefaults(suiteName: "group.com.number1")
    var finArray = userDefaults!.object(forKey: "attribute") as? [Int64] ?? [Int64]()
    let number1 = number.text!
    finArray.append(Int64(number1)!)
    print("from main add")
    print(finArray)

    //let userDefaults = UserDefaults(suiteName: "group.com.number1")
    userDefaults!.set(finArray, forKey: "attribute")
    CXCallDirectoryManager.sharedInstance.reloadExtension(withIdentifier: "com.akshat.Blocking-array.Callblockarray", completionHandler: {(error) -> Void in if let error = error {
        print("akshat"+error.localizedDescription)
        }})

}

Вот мой код расширения callkit

//  CallDirectoryHandler.swift
import Foundation

import CallKit
import CoreData
class CallDirectoryHandler: CXCallDirectoryProvider {

    override func beginRequest(with context: CXCallDirectoryExtensionContext) {
        context.delegate = self
        print("inside beginrequest")

//        let defaults = UserDefaults(suiteName: "group.com.number1")
//        //(suiteName: "group.tag.number")
//        let array = defaults!.object(forKey: "attribute") as? [Int64] ?? [Int64]()
//        print(array)
        // Check whether this is an "incremental" data request. If so, only provide the set of phone number blocking
        // and identification entries which have been added or removed since the last time this extension's data was loaded.
        // But the extension must still be prepared to provide the full set of data at any time, so add all blocking
        // and identification phone numbers if the request is not incremental.
        if context.isIncremental {
            print("insideif")
            addOrRemoveIncrementalBlockingPhoneNumbers(to: context)
            print("insideif")
            addOrRemoveIncrementalIdentificationPhoneNumbers(to: context)
        } else {
            addAllBlockingPhoneNumbers(to: context)
            print("inside else")
            addAllIdentificationPhoneNumbers(to: context)
        }

        context.completeRequest()
    }

    private func addAllBlockingPhoneNumbers(to context: CXCallDirectoryExtensionContext) {
        // Retrieve all phone numbers to block from data store. For optimal performance and memory usage when there are many phone numbers,
        // consider only loading a subset of numbers at a given time and using autorelease pool(s) to release objects allocated during each batch of numbers which are loaded.
        //
        // Numbers must be provided in numerically ascending order.
        print("func addAllBlockingPhoneNumbers")

Но все же, это работает только иногда. Расширение каталога вызовов требует слишком много времени для обновления новых номеров всякий раз, когда я их добавляю. Например: если я напишу номер «А» и нажму кнопку «Добавить», будет вызвана эта функция добавления, и номер «А» будет заблокирован. Теперь, если я добавлю еще один номер, скажем, «B», тогда расширение каталога вызовов не сможет его добавить, и B не будет заблокирован. И теперь, если добавить еще одну цифру «С», то все заблокируется. Я действительно не понимаю этого. Я надеюсь, что кто-то может мне помочь.
