What is the difference between NSURLConnection, NSURLSession and AFNetworking?

Question

I want to know what are the main differences between them and what is the best and most common method of managing web services at the end of iOS in Objective-c and fast.

As before, I worked in Objective-c, and when we need to use webservices, we use AFNetworking and NSURLConnections, after starting NSURLSession I switched to working with this in swift. So, which one is suitable, so I can manage all the conditions of network network services, etc.?
