Having worked through the book, I didn’t see this question addressed (may have missed it).
I’m wondering what common practice is when it comes to editing the default main.m file. On one hand I’ve seen discussions such as this one (stackoverflow.com/questions/7998 … plications) on stackoverflow that suggest there is rarely ever a reason to do it. But I have also seen some example tutorial projects (separate from BNR) that do edit main.m .
What is industry standard for today, or is this more a personal preference thing?
