From Spring 2024, apps that don’t describe their use of required reason API in their privacy manifest file won’t be accepted by App Store Connect.
Although libPhoneNumber-iOS SDK isn't mentioned in Apple's provided list of SDKs (see link below), considering Apple's strict privacy policies, you should add the Privacy Manifest file on your own before it comes into their notice. Lots of the SDKs (Firebase, Facebook, Alamofire, etc.) have already updated their SDKs and added the required privacy manifest file.
