YOU can't swim but your Pokemon can. There is a Hm called surf. I'm not sure where you get it but you teach it to a water Pokemon and when you get near water push a and it will say,"The water is a a deep blue color... would you like to use surf?" And that's how you use and how your Pokemon can swim!
you need to get surf and teach it to a pokemon. Surd is found when in the safari zone (when you reach the end).
Heads north from the resort area until you find a small pond and surf on it.
Teach it the move Surf using HM3.
