The closest the Swedes came was in the men's 400m freestyle, where Victor Johansson set new national records in the semi-finals and final, but his final performance was only good enough for fourth.
Johansson also set a new Swedish record in the semis of the 800m freestyle - his time of 7:44.81 was still only the fifth fastest of the qualifiers, and he was unable to find another gear in the final, finishing fifth in a slower time, behind Tunisia's Ahmed Jaouadi.
Of the 11 individual swimmers who competed in a total of 25 men's, women's and mixed events in Singapore, Johansson was the only Swede to reach a final. Erik Persson reached the semi-finals of the men's 200m backstroke, as did Sara Junevik in the women's 50m butterfly.
Sweden's chances of extending their run of medal success in the pool was lowered by the absence of six-time Olympic and 25-time World Championships medallist Sarah Sjostrom, who is pregnant, but there is still disappointment at the lack of success.
"I suffer with the swimmers who do not get to reach their full potential," said team manager Martina Aronsson to TT.
"We had four finals as a set goal and we did not achieve that. We had higher goals than what was delivered," she continued, believing that the preparations were not to blame, "It's more about what has been done earlier in the season not having been enough."
With no medals in artistic swimming or diving, either, Sweden did not feature among the 29 countries on the World Aquatics Championships medal table, topped by China, ahead of Australia and the United States.
In the swimming medal table alone, the United States finished first, Australia second and France third.
