Crash on + [ReactNativeSupport reloadApp] call with [email protected] #4760

@kkafar

Description

@kkafar

Did you test using the latest Detox?

  • I have tested this issue on the latest Detox release and it still reproduces.

Did your test fail and you're not sure why?

  • I have read the troubleshooting guide and it didn't help me.

What happened?

I'm updating react-native-screens example applications to use [email protected] & my e2e started to fail on calls to device.reloadReactNative(). See the logs below 👇🏻

12:06:49.643 detox[41381] E Command failed with exit code = 1:
jest --config e2e/jest.config.js
Error: Process completed with exit code 1.

I realise that 0.79 is not yet officially supported, but keeping my fingers crossed that we'll be able to figure something out.

I believe the crash might be due to some recent changes (link) & changes to react native setup (link - look at changes to AppDelegate.swift)

What was the expected behaviour?

There should be no crash.

Help us reproduce this issue!

I do not have minimal reproduction, however the problem can be reproduced by:

  1. cloning react-native-screens repo
  2. preparing the repo by following setup instructions
  3. checkout to @kkafar/support-0.79.0-rc.4 branch
  4. yarn (at root level dir)
  5. cd FabricExample && yarn && cd ios && rbenv exec pod install && cd ../
  6. yarn build-e2e-ios && yarn test-e2e-ios

In what environment did this happen?
