Problem with Expo publishing

My app runs perfectly in Ios simulator but it gives me error after I published it. I also asked in the slack channel as well. @ccheever helped me take a look and thought the PropType warning might be the problem but it didn’t appear to solve the problem even after fixing the PropType warning.

Does anyone have a clue what’s going on? Thanks in advance!

it was a problem in your babelrc, for some reason a plugin was set to only be used in development. see this pr for the fix:
