The tag alias #46985 swimmer -> swimming has been rejected.
Reason: "swimmer" does not carry any additional information compared to "swimming". If there is swimming, there must be a swimmer. If there is a swimmer, they are swimming (and if the character is not swimming, they can't be called a swimmer).
Also: swimmers -> swimming
EDIT: The tag alias swimmer -> swimming (forum #294853) has been rejected by @Millcore.
