In 2013, "Swing" was remixed by Australian producer Joel Fletcher, following his breakthrough top 40 hit "Bring It Back" with Will Sparks. Fletcher said of the production of the remix:

"I did Swing in maybe three or four hours before a gig when I was browsing through my iTunes looking for some a cappella to play that night and I came across the Savage track. It was about a year ago. From there, Ministry of Sound heard the tracks and wanted to do something with it. When it got leaked on the internet, I was a bit iffy about when to do with it; I didn't think it would succeed because everyone could get it. They told me to trust them, to revisit the track and rework it. You never know what can happen."^[23]

The Joel Fletcher remix was released on Beatport on 31 October 2013,^[24] then as part of the Australian edition of the compilation Ministry of Sound – The Annual 2014 on 8 November 2013,^[25][26] then as a single on the Australian iTunes Store a week later.^[27] It debuted at number 45 on the ARIA Singles Chart on 18 November 2013, the week of the compilation's release, and climbed continuously for the next two months, reaching a peak of number two on the week of 27 January 2014, behind Pharrell Williams' "Happy".^[3] It placed at number 23 on the Australian year-end singles chart of 2014,^[28] and was ultimately certified quadruple platinum by the Australian Recording Industry Association in June 2018.^[4] It is the highest charting single of both artists in Australia,^[3] and has been credited for "[propelling] the relatively unknown sound of Melbourne bounce to a national audience".^[22] The remix's popularity also caused the original track to return to the Australian charts, re-entering at number 95 on the week of 27 January 2014,^[29] and peaking at number 83 on 17 March 2014.^[30]

Stop, woah, back it up now let me see your hips swing!" was the music used in numerous videos showing Donald Trump dancing at a campaign rally.
