[SOLVED] Standalone app blank screen ios

I don’t know how I switched from managed to bare workflow, but switching back solved this. I only just noticed in the expo diagnostics output.

rm -rf ios android
npm uninstall react-native-unimodules


Hi I need some help with troubleshooting the production standalone app that just shows white screen (or default splash), where it works in expo go. If I run expo start --no-dev --minify it runs fine still locally.

Running expo build:ios and selecting simulator, then installing in simulator locally reproduces the issue, and the logs show…

assertion failed: 20G95 18E182: libxpc.dylib + 50305 [454053CA-B690-3B99-BE31-2369B04EA493]: 0x7d

I am not sure if that is relevant.

If I try and run expo run:ios i get a bunch of linking warnings, and error. I don’t have the knowledge to troubleshoot these…

! ld: directory not found for option '-L/Users/sam/Library/Developer/Xcode/DerivedData/kmapp-chcihbhttvzgsjbxyugjuzigkwwa/Build/Products/Debug-iphonesimulator/react-native-safe-area-context'

X ld: library not found for -lAppAuth

I have tried to route to a simple <View><Text>TEST</Text></View> to see if it would run standalone but it still doesn’t.

Thanks heaps if you can help.

here’s the diagnostic output. I haven’t ejected the app so I don’t know why the workflow says bare. It should be managed. Everything works as it should development wise.
