Answer:
As of my knowledge cutoff in September 2021, the official nicknames for Super Bowl 58 have not been determined or announced. The official nicknames for Super Bowl games are typically not designated until closer to the date of the game, and they often evolve based on various factors such as the teams involved, storylines, and notable events leading up to the game. The nicknames you mentioned, "The Rematch" and "Taylor Swift Bowl/Swiftie Bowl," are not official designations but rather suggestions or ideas based on previous events and popular culture references. It will be interesting to see what nickname, if any, will be given to Super Bowl 58 once the game approaches and more information becomes available.
