Xcode internal error

Hi,
I'm a 14 year old developer for iOS. I was on my 4th application until xcode suddenly stopped working. It will not start and gives me and internal error. Here is the console:

2/28/11 7:02:14 PM Xcode[236] [MT] Uncaught Exception:

On line 20 the face is supposed to be : o (space implied to avoid smiley)
Can someone please help me fix this? I reinstalled xcode, reinstalled mac os x snow leopard and updated everything. I am completely baffled.

Thanks,
Sony

Moved to correct forum. Please read our forum descriptions before posting.

anybody help??????

This has nothing to do with xcode. if you understand the error it means you are trying to call a method that doesn't exist on the underlying object. The class causing you grief is NSCFDate which is not a public class. A quick Google on NSCFDate might help you further. We can't offer much help without your code. Stack traces are not that helpful without the code generating the error.

You're a fourteen-year-old programmer? Me too!

Lol sorry
