CNContacts not fetching all the contacts from contacts list

Question

CNContacts not fetching all the contacts from the contact list. Some of the contacts are missing. Can any one help.

Here is my code.

    let key = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey] as [CNKeyDescriptor]
    let request = CNContactFetchRequest(keysToFetch: key)
    try! contactStore.enumerateContacts(with: request) { (contact, stoppingPointer) in
        let givenName = contact.givenName
        let familyName = contact.familyName
        print(contact.phoneNumbers[0].label!)
        var number = [contact.phoneNumbers[0].value.stringValue]
        var type = [contact.phoneNumbers[0].label]
        if contact.phoneNumbers.count > 1{
            for i in 1...contact.phoneNumbers.count - 1{
                number.append(contact.phoneNumbers[i].value.stringValue)
                type.append(contact.phoneNumbers[i].label)
            }
        }
        let imagedata = contact.imageData
        let contactToAppend = ContactStruct(givenName: givenName, familyName: familyName, number: number, type: type as! [String] , image: imagedata)
        self.contacts.append(contactToAppend)
    }

Please try below code hope it works.

func getContactList() {

  let contacts = self.getContactFromCNContact()

  for contact in contacts {

     //do your stuff with contact
  }
}

func getContactFromCNContact() -> [CNContact] {

    let contactStore = CNContactStore()
    let keysToFetch = [
        CNContactFormatter.descriptorForRequiredKeys(for: .fullName),
        CNContactIdentifierKey,
        CNContactNamePrefixKey,
        CNContactGivenNameKey,
        CNContactMiddleNameKey,
        CNContactFamilyNameKey,
        CNContactPreviousFamilyNameKey,
        CNContactNameSuffixKey,
        CNContactNicknameKey,
        CNContactOrganizationNameKey,
        CNContactDepartmentNameKey,
        CNContactJobTitleKey,
        CNContactPhoneticGivenNameKey,
        CNContactPhoneticMiddleNameKey,
        CNContactPhoneticFamilyNameKey,
        CNContactBirthdayKey,
        CNContactNonGregorianBirthdayKey,
        CNContactNoteKey,
        CNContactImageDataKey,
        CNContactThumbnailImageDataKey,
        CNContactImageDataAvailableKey,
        CNContactTypeKey,
        CNContactPhoneNumbersKey,
        CNContactEmailAddressesKey,
        CNContactPostalAddressesKey,
        CNContactDatesKey,
        CNContactUrlAddressesKey,
        CNContactRelationsKey,
        CNContactSocialProfilesKey,
        CNContactInstantMessageAddressesKey] as [Any]

    //Get all the containers
    var allContainers: [CNContainer] = []
    do {
        allContainers = try contactStore.containers(matching: nil)
    } catch {
        print("Error fetching containers")
    }

    var results: [CNContact] = []

    // Iterate all containers and append their contacts to our results array
    for container in allContainers {

        let fetchPredicate = CNContact.predicateForContactsInContainer(withIdentifier: container.identifier)

        do {
            let containerResults = try contactStore.unifiedContacts(matching: fetchPredicate, keysToFetch: keysToFetch as! [CNKeyDescriptor])
            results.append(contentsOf: containerResults)

        } catch {
            print("Error fetching results for container")
        }
    }

    return results
}
