Wycombe hauled back a two-goal deficit to claim a point at the Vetch.
Leon Britton's move to central midfield transformed the Swans
Leon Britton's switch to central midfield sparked Swansea after a poor first half, his run and pass setting up Paul Connor for a composed first goal.
Lee Trundle won and finished a penalty after being set up by Britton's pass, before Roger Johnson pulled one back.
Weak set-piece defending let Johnson head in from Joe Burnell's cross, then Steve Guppy's 25-yard cross from a free-kick sailed straight in.
