You're assigning a value to theSettings. That's what the "assignment"
in the warning message refers to. What is theSettings declared as?
You should fix your code so that all warnings go away. Warnings
almost always indicate that something could potentially go wrong, so
you might as well take away that possibility. Also, if you ignore
warnings you think it's safe to ignore, you may not notice when an
important warning appears. When I upgraded to Xcode 3, I got a whole
bunch of probably harmless warnings, but I fixed them all for this
reason.
That said, some people have different ideas about what the compiler
should warn you about, and set their build settings accordingly.

I have a loop that gets the user's home directory, and then adds a
string to complete the file path for several files.
This line:
theSettings = [NSHomeDirectory() stringByAppendingPathComponent:
[myPrefs objectAtIndex:i]];
gives me a caution sign when I compile. It says "assignment from
distinct Objective C type", but the code works.
How important is it to fix that? Also, should my code be "caution
free" as a sign of clean coding or can some cautions that don't
affect functionality be dismissed?
Thanks,
