If you will use this method to check internet connection and your device has been connected to the Internet by 3G/LTE, the result of the CFNetDiagnosticCopyNetworkStatusPassively will be -66557L, means "kCFNetDiagnosticConnectionDown".
This bug was confirmed by Apple with the ID #12443370.
So, as I understood, the best way to check the internet connection is just using such *NetworkReachibility framework, but it's so terrible: if you wanna just check this so easy issue, you have to download GitHub repo's with custom implementation, using cocoa pods or submodules, or, more 'optimize' way - just download the Reachability{.h/.m} files from the Apple example and import them into your project.
Good job, Apple.
ps. this small post I wrote after such quick comprehension of the Android and iOS abilities to check internet connection.
