Sorry, I was a little bit to quick there...
I get an error
169: DBOut( @"Hello World!" );
/AppController.m:169: error: syntax error before ']' token
Did I miss something?

I thought I'd share this with those of you who want an alternative
to NSLog(). If you want your debugging output to always go to the
debugger console without all the date and time stamping info, just
place this bit of code in your <AppName>_Prefix.pch file. Then
define the __DEBUG_OUT__ preprocessor macro in your Project
Settings for Debug builds.
Once you have done this, debug output only occurs for debug builds.
For release builds, it's as if the debug output code never existed.
Usage:
For NSString-style output use DBOut() the same way you would use
NSLog().
For char *string output use DBCOut()
Enjoy!

#ifdef __DEBUG_OUT__
#define DBOut(fmt, ...) fprintf(stderr, "%s\n", [[NSString
stringWithFormat:(fmt), __VA_ARGS__]
cStringUsingEncoding:NSUTF8StringEncoding])
#define DBCOut(fmt, ...) fprintf(stderr, fmt, __VA_ARGS__)
#else
#define DBOut(fmt, ...)
#define DBCOut(fmt, ...)
#endif
