iOS display backtrace with method names also in released product - ios

Question

I wanted to have a backtrace with the classes and method names displayed every time the app crashes. I managed to do it in debug mode, using this code (the printTrace function just prints the string on a file.):
void HandleException(NSException *exception)
{
[SILogManager printTrace:[NSString stringWithFormat:#"******************** CRASH *********************"]];
[SILogManager printTrace:[NSString stringWithFormat:#"-> Stack Trace: %#", [exception callStackSymbols]]];
}
Although this won't work when the app is released, because it will produce a stacktrace like this one:
******************** CRASH *********************
-> Stack Trace: (

And I don't find it very useful.
I've also already tried to call backtrace and backtrace_symbols manually, but it doesn't work!
In the project properties, I have the following settings, that should copy all the dynamic symbols when building, so I still can't figure out why it isn't working!
What can I do to have this feature also in the released app? What am I doing wrong?
Thank you in advance!
