We can’t use default Cocoa implementation from iOS, instead we have another implementation suitable for Linux: GNUstep.

Needed steps:

1. Install headers for gcc:
   sudo apt-get -y install build-essential
2. Install GNUStep:
   sudo apt-get install gobjc gnustep gnustep-make gnustep-common
3. Add next line to .bashrc
   #GNUSTEP Environment vars
. /usr/share/GNUstep/Makefiles/GNUstep.sh

And you are good to go. How to create make file and Hello World follow this link: Getting started with Objective C on Ubuntu.
