Kinda reminds me of writing PHP code where you don't realize you have a typo until your program crashes and burns at runtime!!!
I accidently typed NSStringwithFormat instead of NSStringWithFormat and that caused my iPhone app to crash.
You'd think XCode's autocompletion would help but so far it just seems to get in the way more often than not :(
Oh well I guess I will learn to hate it less the more I use it.
