macOS Is it possible to run NSTask as user ?

I am using LaunchDaemon , which launches a binary from root session .

Now ,when I execute shell command using NSTask , It would run as a root User .(Example : I run "whoami" , It would respond as "root")

Is it possible to run NSTask (from daemon launched binary ) as a loggedon user ? (Example : I run "whoami" , It should respond as "UserName")
