Is “symbolicating” really a word? Apple seem to think so. When you get a crash log back form them they have removed all the symbols (names of your classes and methods) and replaced them with numbers. To find out where your app crashed, you have to replace the numbers with their original symbols. They give you a tool but it is not easy, and they call the process “symbolicating”. Personally I would call it “symbolizing” as you are replacing one thing for another that represents it.
