Example 7.1 not giving any output in Xcode 4

When I run example 7.1 in xcode 4
I get no output, a new gray window appears, it stays empty and I get no out put but not errors either.
Any suggestion?
Thank you.

Are you getting output from your other program examples? Make sure in XCode 4 that the Console view appears (and not just the Variables view). I've been burned by that before.
Cheers,

Hi,
Thank you so much for your quick response, I really appreciate.
I found what the problem was.
Xcode 4 automatically had this line inserted (in red):
int main(int argc, char *argv[])
{
return NSApplicationMain(argc, (const char **)argv);
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
Fraction *myFraction = [[Fraction alloc] init];
[myFraction setNumerator: 1];
[myFraction setDenominator: 3];
I am not sure what it does but after I put the comments marks and disabled it works.
It is a bit confusing reading the book that was based I assume on Xcode 3 and using Xcode 4 since things do not match exactly.

Andrea,
You didn't start with a Command Line Tool, which is why that line was in there. Also, the 3rd edition covers XCode 4. I try my best to keep up with Apple's changes.
Cheers,
Steve
