Just remember to let the phone dry fully before charging (unless you’re charging wirelessly of course). Moisture while charging gradually damages both cable and port.
iPhones are actually able to detect this and will give a pop-up saying moisture has been detected in the charging port and charging has been disabled out of safety concerns. It even shows you a bypass button for emergencies!
I get a similar notification when I take Apple Watch surfing. Also took an iPhone 11 in a waterproof bag around my neck for pics, but it was a hassle to zip up the wetsuit, and the bag fogged up.
