Your question is very vague, you should try asking more specific questions, like "what AVCaptureSession does" and etc.
There's a whole book about AVFoundation: https://www.amazon.com/Learning-Foundation-Hands-Mastering-Framework/dp/0321961803
It's mostly about video editing, but it also has some things about recording. Book explains the things more or less easily, but it costs money :(.
AVFoundation is quite hard to grasp (IMHO, only CoreData is more complicated than AVFoundation), and I had a lot of troubles trying to understand it too. That was 2 years ago, and looks like there's still not much tutorials about AVFoundation.
My advice is just to watch every WWDC video there is (starting from WWDC 2010), read Apple's AVFoundation programming guide, check every tutorial there is, and eventually you will start to understand things. But it will take some time, yeah.
