Custom VNC client for iPad/iPhone?

I'm looking around to see if there's a library for building my own roll 开发者_高级运维of VNC for iPhone/iPad ... from what i saw now; the only library that 'could' meet my needs is 'Chicken' (a fork of CoVNC)

Seems to be for MacOS but 'should' be running on iOS, right ?

(Sorry for my newbee'ness, starting here).
