Networking was born out of the necessity of having a simple networking library that doesn't have crazy programming abstractions or uses the latest reactive programming techniques, but just a plain, simple and convenient wrapper around NSURLSession that supports common needs such as faking requests and caching images out of the box. A library that is small enough to read in one go but useful enough to include in any project. That's how Networking came to life, a fully tested library for iOS, tvOS, watchOS and OS X that will always be there for you. Initializing an instance of Networking means you have to select a NSURLSessionConfiguration. The available types are Default, Ephemeral and Background, if you don't provide any or don't have special needs then Default will be used.
