Note: The first version of the results erroneously recognized 3 performances as records. The Women's 50m Breaststroke results recorded championship record performances from Alexanne Lepage and Eneli Jefimova in the heats. Likewise, the performance from Kuzey Tuncelli in the final of the Men's 800m Freestyle was recognized as a championship record. Each performance was slower than the existing championship record. All results were later amended.
