CoreServicesLayer

Gain access to fundamental iOS services with the frameworks in the Core Services layer. With these services, access files, low-level data types, Bonjour services, network sockets, and more. Use the frameworks in this layer if those in the Cocoa Touch and Media layers aren't sufficient for your needs. When you use the technologies at the Core Services layer, you'll automatically take advantage of the Core OS layer without getting into its details.
