Answer 1

Firstly you need to enable your CallBlocker app in App Setting for that follow this -

Go to Settings->Phone->Call blocking & identification->Enable your App.

After that use addIdentificationEntry for adding entry

  private func addIdentificationPhoneNumbers(to context: CXCallDirectoryExtensionContext) throws {

        let phoneNumbers: [CXCallDirectoryPhoneNumber] = [ 18775555555, +919899999999 ]
        let labels = [ "Telemarketer", "Local business" ]

        for (phoneNumber, label) in zip(phoneNumbers, labels) {
            context.addIdentificationEntry(withNextSequentialPhoneNumber: phoneNumber, label: label)
        }
    }

Which is working fine in Xcode 8.x swift 3.x
