Assuming that you used the default uniformIntRand object (did not create an
instance of the UniformIntRand class explicitly in your code) you can simply
say:

[randomGenerator setSeed: YOURSEEDHERE];

Since the uniformIntRand instance is seeded from the RandomGenerator
instance (both are created when you call an initSwarm macro.)
