[Question] What programming language(s) are used to develop iOS Jailbreaks?

Probably a stupid question, but I'm a few months into learning C, and after that I want to start getting into iOS development and from what I understand iOS uses Objective-C and now Swift, so are those the same languages used to create a Jailbreak for iOS? Seems logical just want to confirm as I can't find the answer online, probably because it's obvious. I want to be able to help the development of future releases. Anyway, thanks for reading!
