How do I declare a debug only statement

Question

In C# I can use the following code to have code which only executes during debug build, how can I do the same in Xcode?

#if DEBUG
{
    // etc etc
}
#endif

DEBUG is now defined in "debug mode" by default under Project/Preprocessor Macros. So testing it always works unless you have a very old project.

However I hate the fact that it messes up the code indentation and not particularly compact. That is why I use another macro which makes life easier.

#ifdef DEBUG
#define DEBUGMODE YES
#else
#define DEBUGMODE NO
#endif

So testing the DEBUGMODE value is much more compact:

if (DEBUGMODE) {
//do this
} else {
//do that
}

My favourite:

NSTimeInterval updateInterval = DEBUGMODE?60:3600;
