Guard Split switches the user's Defense and Special Defense stat stages with those of the target Pokémon. Since this changes stat stages, the stat stages can be passed via Baton Pass.
Guard Swap bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly.
