Translation of shipwreck in Spanish

Dear Maximilian, I look forward to your visit in Switzerland. After a somewhat difficult start, it seems that we have increased the website traffic and we are starting to receive more visitors.
I have began to learn English. I like to swim and to dive, because I lived near the beach while I lived in Miami. It is not similar to any other sport. But this week have not been yet to the pool.
Thank you for your email, everything was crystal clear. We should call each other, this would be the best way. Do you have the same opinion? But I think I need more help, for example: how do you conjugate swim?
