Swim Fix
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Swim Fix
An Architectury mod that fixes Minecraft bug MC-220390 for swimming in water.
About The Bug (From Minecraft Bug Tracker)
If you hit an entity while swimming underwater, the player will stop swimming for a brief moment (it changes the size of its hitbox and returns to the swimming one) and then get stuck in the middle of the water if they try to swim below a block (the player gets stuck when their large hitbox collides with a block, even if they are using a different size hitbox).
