The Canaries had stunned their high-flying hosts with goals from Steven Whittaker, Sebastien Bassong and Grant Holt giving them a 3-0 half-time lead.
Swansea rallied through strikes from Michu and Jonathan De Guzman, but Robert Snodgrass made sure of the win with an excellent free-kick, before Michu netted again in injury time.
