Yes.
Because the swimmer is trying to swim with the same speed as he swims in the still water. It doesn’t matter whether the river is flowing or not, the velocity of the swimmer with respect to river will be same. However what the observer standing on the bank will be seeing a different velocity which we call actual velocity of swimmer as it is the velocity with respect to ground.
