I have seen spanish speaking staff at this location. You can make a Genius Bar reservation when it’s convenient for you and add this to your “notes” or special request at the bottom of the form. Hope this helps you get help in spanish! Here’s the link to Apple support page for making a Genius Bar appointment: https://getsupport.apple.com/?caller=grl&locale=en_US
Unfortunately, I have not been in Apple. Been to many stores, and many of them have someone that speaks Spanish.
