Their return is a boost for Bilic as he looks to guide West Ham, who have four points from six games after a tough start to the season, out of the bottom three.
"Manuel Lanzini is back in the squad. He will be in the squad against Swansea," Bilic told the club's website (www.whufc.com).
"His (Antonio's) injury wasn't that bad and there was always a chance he would be available for the game with Swansea," he added.
West Ham completed the double over Swansea last season, winning 4-1 away before Cheikhou Kouyate's strike sealed victory at the London Stadium.
"That we beat them twice last season – it means something, but on the other hand, it doesn’t mean a thing just before the start of the game," Bilic said.
"To me, it just means we look very motivated in training and we look good and we have the players back... now we have that opportunity and possibility to get out of this end zone."
West Ham have lost only one of their last nine league games against Swansea. The Welsh side have collected five points from six games this season.
