Getting straight to the point this non fatal error message has a 1 line patch

Using XCode 13.0 and installing on an iPhone 11 running iOS 14.8

PhoneNumberKit repeatedly generates the following non fatal error message:

Updating selectors after delegate addition failed with: 
Error Domain=NSCocoaErrorDomain Code=4099 
"The connection to service on pid 87 named com.apple.commcenter.coretelephony.xpc 
was invalidated from this process." UserInfo={NSDebugDescription=
The connection to service on pid 87 named com.apple.commcenter.coretelephony.xpc 
was invalidated from this process.}

Repeatedly means 4 x for a view with 2 x phone fields.

Prior to using PhoneNumberKit I was directly accessing CoreTelephony to interrogate the serviceSubscriberCellularProviders to find the active carrier. The point being I was getting this "service on pid 87 error" and implemented a one line fix let info = CTTelephonyNetworkInfo() which (I assume) delays garbage collection sufficiently to prevent this error.

import Foundation
import CoreTelephony

class CountryCode {
    static let shared = CountryCode()

    /* The line below prevents this error
