How about a personalized swim cap for your friend? You can include their name or a motivational quote. Another option could be a waterproof action camera so they can capture their swimming techniques and improve their performance. A water-resistant MP3 player would also be a great gift, allowing them to swim to their favorite tunes. Finally, a subscription to a swimming magazine or access to an online course on freestyle swimming could be a thoughtful present.
