I don't know why, but every time I try to build, I get these "duplicate symbols for architecture x86_64" errors.
They have nothing to do with my code, they're just unexplained obstacles that hinder my productivity and waste my time for no reason whatsoever...
And to be honest I'm just tired of wasting my time trying to fix them.
So if there's anyone out there who knows how to fix this, thanks in advance.

Yes. You need to run your Terminal with Rosetta (Get Info, then check the box), and then run your build command from there. If your Mac has an M1 chip and you want to do mobile development, you need to run pretty much every program with Rosetta, or you'll be swarmed by errors with every command.
