run Kill, build, and launch Snapzy.app (default)

--logs, logs Launch then stream unified logs for process == "Snapzy"

--telemetry Launch then stream unified logs for subsystem == "$LOG_SUBSYSTEM"

--debug, debug Build then launch the app binary under lldb

--verify, verify Launch and confirm the Snapzy process is running

${BOLD}Options:${NC}

--configuration C Build configuration. Default: Debug

--derived-data PATH Build DerivedData path. Default: .build/xcode-derived-data

--log-level LEVELS default,info,debug,error,fault,all. Default: default,error,fault

--clean Clean before building
