Hello Shaimae,
No, you do not need to do anything to enable it. The “swapna” command has been included in Chimera for a very, very long time.  It you have an extremely old Chimera version you should try getting a newer version, in case that is the problem.  

Besides trying to use the “swapna” command, you can also check by using command “help swapna” which should show the manual page.
I hope this helps,
