Although Swarmers don't have a high attack rate against Ground Heavies, they can be useful by providing a gang-up bonus to the next unit that attacks.
The biggest challenge with using Swarmers is keeping them alive. They are easily killed by most anti-air units that can get within range of killing it. Thus, it is of utmost importance to keep them behind a line of Underlings, Pinzers, and/or Garudas.
In a pinch, Swarmers can be sacrificed by flying up to the enemy front-line in order to damage a back-line unit like Engineer or Walker with its 2 range. However, this usually results in the Swarmer dying, so this is only an efficient trade in certain situations where the damage it does will prevent something horrible from happening.
