A high angle of slip scares the hell out of the passengers and puts the wingtip dangerously close to the ground.

I was told by an airline transport pilot that s swept wing plane cannot be safely slipped unless it is at or below wing in ground effect altitude. So which is it?

With a swept wing aircraft you will have a large difference in lift on the one wing in a slip as opposed to the other due to the incidence of the airflow on the forward wing as opposed to the trailing wing. You can also have a blanking effect on the rudder. Relative to ground effect and slipping on a swept wing plane I profess ignorance. I am sure a heavy metal driver will chime in with an explanation.
