ExpoKitApp assertion failed: libxpc.dylib, where to start?

Unhandled JS Exception: Module AppRegistry is not a registered callable module (calling runApplication).

Fails running the build:
expo build:ios -t simulator

Works running locally in Expo:
expo start --no-dev --minify

Where to start? I’d like to avoid starting over and step by step add back my whole app… Surely there is some other way to debug what goes wrong?

Need help please…

I realize that “assertion failed” comes also if stripping the app back to the expo init example, where the app works.

That means I have no logs to go on except “Unhandled JS Exception: Module AppRegistry is not a registered callable module (calling runApplication).” in the phone display.

Where to start?

Ok, after a long day of cutting code base in halves, I found the issue:

“scheme” was missing in the app.json, hence it worked in the expo app but caused an obscure error in the standalone app as a const was preparing a Linking during startup in one file.

I’ll post suggested improvements in the github repo.
