Video chat iOS app?

Question

Objective-C

Hello.
Tell me how video chats are implemented on iOS, and services for their implementation.
It is important that, in addition to purposefully connecting users to each other, it is possible to make a separate chat with random connection of users to each other (something like ChatRulet).
I know how to make instant messengers using Parse.com, is there a big difference between them in development.
Just don’t say something like: if you ask this question, then you won’t be able to cope with this question and other similar things, as they like here. Yes, I'm not a master at this and I'm just learning, but I'm trying.
Thank you for your attention.
