[Reverse] DSYM - Stuck on challenge

Hi all,

I’ve been stuck with this challenge for quite a while. I’m currently trying to understand the main assembly functions using ida free and also using gdb to try to the debug the program. I believe i identified some of the places where i can execute some breakpoints, but the program is not showing any data while running it.
Is there any hint that someone could give me privately to avoid spoiler?

Thanks guys!
