"They had a few good opportunities. After that, we got better and they didn't cause us many problems.
"Overall, though, I think we kept possession well and created a few chances. We just couldn't score a second goal.
"Swansea is a tough place to come but we're disappointed we didn't go home with three points."
The Reds, who still top the Barclays Premier League, must regroup quickly, in time for the home games against Newcastle United (26 December) and West Bromwich Albion (29 December).
"We now have three games in the next nine days," Vidic said. "Obviously we have a few players who are coming back from injury and they will be important for that period."
