How to integrate Native Code with Lua to create plugins?

Hello, I have a good knowledge of Swift and Objective-c, I would like to create my own plugins to use with Corona, but I don’t know what to use to make lua code interact with Apple native languages, could anyone point me to some how to do this?

Have you checked out our documentation yet? http://docs.coronalabs.com/native/index.html

This tutorial is a little older, but it should be mostly relevant: http://docs.coronalabs.com/tutorial/native/iosIntro/index.html
