I get this error when I run yarn ios. I’ve tried to clear the simulator’s data and restarted it.

What is front board and is my bundle identifier broken??? Expo works when I’m in a managed workflow :slight_smile:

Same issue here with expo init app and bare-minimum typescript template

make sure you’re using the latest version of xcode, and clean your build
