Yeah, not a good thing.

Put a 'pwd' after the cd to verify you changed directories. You should have
changed dirs or gotten an error is you don't have perms to get into that dir
( the dir not existing is definitely lack of perms :).

What is swikit.sh? Does it exist? Is it executable?

Just like you did.

If you just need it for a single commandk, then stick it in a parens.

( cd somewhere; run-command )

That uses a subshell, so avoid doing that in loops that run many, many
times.

$ cat /etc/init.d/swiki
#!/bin/sh

/usr/bin/squeak -headless /usr/local/lang/squeak/squeak.image
/usr/local/lang/squeak/start.st &

That's what it should look like if everything worked. Actually there should
be start and stop stuff :). Does swiki come with an example startup script?
