His family said he had been suffering from an ongoing medical condition and died from a seizure in his sleep on Saturday (July 6).
Boyce's first role was in the film Mirrors when he was nine years old. He went on to become a Disney Channel star in shows like Jessie and the TV movie series about the children of Disney villains, Descendants.
He also played Adam Sandler's character's son in the Grown Ups films.
A number of his former co-stars have paid tribute to Boyce. See some of their messages below.
Rest in peace, you'll always be in our hearts ❤ https://t.co/eYQT5XIswd— Disney Channel PR (@DisneyChannelPR) July 7, 2019

I don't even know where to start... I am at a loss for words. I never thought in a million years I would be writing this. Cam, you were one of a kind. My heart will be forever broken. I am so happy that I got to spend almost everyday with you on set, you gave the best hugs. I wish I would have hugged you tighter when I saw you a couple of months ago. Thank you so much for being the big brother I never had... I am so distraught and I cannot stop crying! I love you so much... fly high 👼🏼 💔😢 Gods best Angel . #CameronBoyce
