The Red Devils took the lead via Javier Hernandez's opportunistic strike in the 39th minute, but Michu levelled things for Swansea with a fantastic volley from Dyer's cross.
Just when it seemed as if the game would be headed for a draw, United, like they have done countless times under Ferguson, got their winning goal late in the game when Rio Ferdinand volleyed Van Persie's corner into the back of the net.
Here, FOX SPORTS rates the players who took to the pitch for Ferguson's last professional game at Old Trafford as United manager.
David De Gea - 7
De Gea was not really tested in the first-half but had to be alert to make several smart stops in the second half to deny the likes of Hernandez and Dyer from scoring. He has developed into one of the finest shot-stoppers in Europe but still needs to work on his aerial dominance.
Phil Jones - 7.5
What Jones lacks in technical quality, he more than makes up for it with heart. The versatile defender performed admirably against Swansea and made several well-timed tackles during the course of the game, including a crucial last-ditch sliding challenge on Dyer to prevent him from getting his shot away.
Nemanja Vidic - 7
Despite having nothing left but pride for United to play for, they still gave their all against Swansea and remained committed as ever. This incredible commitment was best displayed by Vidic, who bravely put his body on the line to block several goalbound shots.
Rio Ferdinand - 7.5
One of the Ferguson's best ever signings, Ferdinand popped up to give his boss the perfect send-off at Old Trafford with a well-taken goal late in the game, volleying home expertly following Van Persie's corner. The former England international was also excellent in defence and used his experience to make several crucial interceptions.
Patrice Evra - 7
Evra threw off his defensive shackles and rampaged up field more often than usual. But while he managed to provide United with a genuine outlet of attack on the left flank, he often left Vidic and Ferdinand exposed in defence whenever Swansea counter-attacked and can thank his lucky stars Michael Laudrup's men failed to make their chances count.
Michael Carrick - 7
Compared to the high standards he has set this season, Carrick had one of his quieter games for United in the middle of the park. But the former Tottenham Hotspur player still managed to make several key passes from deep and even managed to break up a few Swansea attacks.
Paul Scholes (66' off) - 7.5
Regarded by many as one of the best midfielders the world has ever seen, it felt a little bit of a let-down that Scholes failed to cap off his last professional game at Old Trafford with a goal. But the 38-year-old still proved an influential figure in the middle of the park, spreading the passes well with his typically accurate cross-field passes. Statistics show Scholes completed an amazing 93% of his passes in the game. It was as much a perfect send-off for him as it was for Ferguson, and his presence on the pitch will definitely be sorely missed by United next season.
Danny Welbeck (67' off) - 6
Welbeck still has some way to go before he can establish himself as a first-team regular. The 22-year-old, who is currently behind both Van Persie, Rooney and possibly Hernandez in the pecking order up front, failed to make the most of his rare start for the Red Devils and was largely anonymous in the game.
Shinji Kagawa - 7
Kagawa showed some good touches in and around the box, linked up well with Van Persie and proved a tricky customer for Swansea's defence. He will need to work on keeping his composure in the final third however as his control often let him down when put in good goalscoring positions.
Robin van Persie - 7.5
The Dutch international was pulling the strings in attack for United throughout the game, combining well with the midfield and threatening Swansea's defence with his quick feet and threatening set-pieces. Van Persie may not have got himself a goal, but he will be credited for an assist after Ferdinand scored via his corner.
Javier Hernandez (75' off) - 7.5
Hernandez is undoubtedly one of the best "poachers" in the modern game. His clever off-the-ball running kept the likes of Williams and Chico busy, and it was he who gave his side the lead with a predatory strike as he pounced on a loose ball in the box before clinically slotting past Tremmel.
Antonio Valencia (66' on) - 6
Valencia's impact as a substitute was negligible, and questions must surely be asked of whether the Ecuadorian international deserves to stay on at United for much longer.
Anderson (67' on) - 6
Like Valencia, Anderson did not make a positive impression when he entered the fray. He was too slow on the ball and got caught in possession numerous times, while his passing was erratic at best.
Ryan Giggs (75' on) - 7
It must have been an emotional night for Giggs, who played his last home game for Ferguson. The Welshman showed his class with a series of neat passes in the final third and set up a few decent goalscoring opportunities for his team-mates when he came on.
Gerhard Tremmel - 7
Tremmel performed admirably in the Swansea goal, making numerous saves and showing great anticipation to collect the crosses into his box.
Dwight Tiendalli - 6.5
Tiendalli had to deal with the threat of the overlapping Evra, but he managed to hold his nerve majority of the time to prevent the Frenchman from making inroads.
Chico Flores - 7
Chico was tasked with keeping a close watch on Van Persie, and he did his job very well as he stuck close to the Dutch striker to prevent him the time and space to create havoc in the final third.
Ashley Williams - 7
Like Chico, Williams was generally stable in defence and dominated majority of the aerial duels. He commanded his team well from the back, and Hernandez found it hard to find a way past the Welsh international.
Neil Taylor (65' off) - 7
Taylor was quietly effective on the left and showed great tactical awareness to cover for his centre-backs whenever they were caught out of position. He showed great industry to bomb up whenever he could as well and delivered a few good crosses into the box.
Leon Britton - 6
Swansea's "pass master" appeared lethargic and did not really manage to get into the game. Britton did manage to keep possession well whenever he had it, but he did not do enough for his side offensively.
Jonathan de Guzman - 7
De Guzman's disciplined showing helped ensure Swansea would always have a man in the middle of the park to slow United's counter-attacks down. The Dutchman was also neat in his passing and recycled possession very effectively.
Wayne Routledge - 7.5
One of Swansea's livelier players on the night, Routledge's pace and trickery made him a handful for United's defence. The 28-year-old often found himself in good positions around the box and earned his side a number of free-kicks in dangerous areas.
Pablo Hernandez (87' off) - 7
Hernandez took some time to get into the game, but he gave Ferdinand and Vidic a real headache when he finally found his feet. The Spaniard's clever use of the ball was a joy to behold and did very well to test De Gea on a number of occasions.
Nathan Dyer - 6.5
The winger used his pace to exploit Evra on the right flank, but his final ball often lacked accuracy and Laudrup will surely be expecting the 25-year-old to be more productive in the attacking third for future games. He will be credited with an assist after his cross was brilliantly turned in by Michu.
Michu (74' off) - 7.5
Michu struggled early on in the game, but his goal, an expertly struck half-volley past De Gea, instilled a measure of confidence in him. Michu visibly got more involved in the game after his goal and helped set his team-mates up for numerous goalscoring opportunities.
Ben Davies (65' on) - 6.5
Davies had an average game for Swansea when he came on. He was tidy in possession and defended well as a whole.
Angel Rangel (74' on) - 6.5
Rangel made a nuisance of himself during set-pieces when he came on and very nearly got himself on the scoresheet with a solid header which grazed the top of the bar.
Kemy Agustien (87' on) - N/A
