It’s been a long time coming for PC classic Terraria to get a Switch port after re-releasing everywhere else including Android and iOS. Finally though, the game with all major PC content (as of now patch 1.3) is available to buy on the Nintendo e-Shop.
The patch notes describing new Switch enhancements for touch screen and HD rumble mention this is a port of the game based only on the PC version and will not include Mobile or Console exclusives previously appearing in other ports of the game.
Developer Re-Logic says physical editions of the game are still definitely planned but are not ready in time for the game itself to be complete. Check it out on the e-Shop.
