iOS 12

iOS 12 lets developers create extensions for reporting unwanted texts and calls as spam

iOS 10 included a CallKit framework that brought a system-wide way for customers to use specialized apps on their iPhone, like Hiya and TrueCaller, that automatically identify and block nuisance calls before the phone even rings. With iOS 12, Apple started allowing developers to write new types of call-blocking extensions that gather information from the user before deciding whether to report or block the number.
