Coming up with the right name for a variable or a function can easily become the most difficult part of my day. I always wanted to open variable and function names consultancy.
if you get stuck, just do the objective c thing:
aInt, anArray, aXMLFile, etc. Still fairly generic, but still useful and easy to read (vs single letter variables or random things. Worse comes to worse, you can also just make a sentence out of it.
