i want convert function.

func commmand (argument: string) -> string {  let task:nstask = nstask() let pipe:nspipe = nspipe()  task.launchpath = "/bin/menubar" task.arguments = ["argument"] task.standardoutput = pipe task.launch()  let handle = pipe.filehandleforreading let data = handle.readdatatoendoffile() let result_s = nsstring(data: data, encoding: nsutf8stringencoding) return result_s } commmand getip
