The Black Cats got off to a flyer as Jermain Defoe tapped into an empty net following Fabio Borini's effort in the third minute before Gylfi Sigurdsson replied for Swansea from the penalty spot after Wes Brown was penalised for bringing down Andre Ayew in the area.
Despite being reduce to 10 men, Swansea took the lead five minutes before the break through a fantastic individual effort from Ayew to give Alan Curtis' outfit the advantage at the interval.
A lively start to the second half saw Sam Allardyce's men draw level through Patrick van Aanholt's deflected shot four minutes into the second half before Defoe netted his second of the match on 61 minutes, racing onto a through ball from Adam Johnson, to put the Black Cats 3-2 up.
Defoe then completed his hat-trick late on from a rapid counter-attack as Sunderland went home with all three points to jump above local rivals Newcastle United into 18th position with Swansea remaining 17th, teetering above the drop zone.
