Swimming is good for recovery and aiding breathing but it's not going to get you in any sort of shape for boxing. Cycling would be far better than swimming as well, not as good as running as you're not on your feet and you don't contract as much muscle (so VO2 will be lower) but still far more beneficial then swimming.
Eh, please sign up to sherdog and explain this to the fucking morons on the S+C section.
