Detox: [RN 72] iOS Simulator cannot terminate app

What happened?

Added Detox to an existing react native project. It failed to complete the detox test command due

child-process:EXEC_FAIL “/usr/bin/xcrun simctl terminate B9AD5297-A76B-41D8-9C0F-435F87BBE3B3 org.reactjs.native.example.AwesomeProject” failed with error = ChildProcessError: Command failed: /usr/bin/xcrun simctl terminate B9AD5297-A76B-41D8-9C0F-435F87BBE3B3 org.reactjs.native.example.AwesomeProject An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=3):

After reading about others who had similar issues, I assumed it was my project configuration. So I then used the sample in React Native and confirmed the AwesomeProject successfully deployed on the simulator. Then followed the instructions from the Detox site and successfully ran detox build; However, it fails in the same way as my original project.

MacBook Pro - M1 2020 macOS Ventura 13.4.1 Xcode 14.3.1

detox test -l verbose --cleanup --configuration ios.sim.debug

What was the expected behaviour?

The iOS simulator would terminate the app

Was it tested on latest Detox?

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

Did your test throw out a timeout?

I am also experiencing this issue after upgrading react native to 0.72.3

It sounds like there’s an issue with RN 72 and Detox. We don’t officially support this version yet, but we will soon. We will take this issue into consideration when upgrading Detox to comply with RN 72.

i’m running into the issue still with detox 20.19.1 when using xcode 15.2.0 RN 0.70.13 in circleci.

Hi all. With same codebase I’m able to reproduce this bug on machine with XCode 15. But it works well with previous XCode version. I’ve applied patch to detox@19.13.0. As a temporary solution to disable termination.

after updating XCode to latest 15.0.1/15A507. it works well without patch. I think it was xcode issue. Tried on mac-m1 with “react-native”: “0.72.6”, “detox”: “^20.13.5”,

PetroPavlenko on Nov 1, 2023

react-native “0.71.14”, encountered the same issue. Then upgraded detox from “^20.5.0” to “^20.13.5”, the issue resolved. By the way, my xcode version is “15.0.1/15A507”

Hate to be a “me too” without anything substantive to add, but adding anyway just to reflect another user with the same problem. I can reproduce this reliably on my M1 Mac, v19.12.6 on 0.72.6. It fails within seconds of invocation.

If/when I find anything interesting I’ll be sure to update.

Guys, we will only advance here if you create some exact reproduction repo. I understand you have an issue, but the conditions to reproduce this issue seem much more specific than originally described. There has to be something else in the equation.

You seem to report different RN and Xcode versions, whereas I try both Xcode 14.3 and 15 and I don’t see any issues with app termination. There has to be something more to it.

I created a fresh RN app npx react-native@latest init AwesomeProject and ran Detox tests on it – termination happens just like expected.

Some of my colleagues are seeing this on “react-native”: “0.72.4”, “detox”: “20.9.1”,

hi @kvramyasri7, we use

"react-native": "0.72.5"
"detox": "^19.13.0",

BTW in our version we added NO_FLIPPER config in react-native.config.js and installed pods without flipper. Otherwisedetox build is failing. Also IOS 17 version on simulator is 3 times slower in our CI machine. So we switched to IOS 16.4. p.s. this version of react-native has support of XCode 15.

I’m seeing the same issue with RN 0.71.11 and Detox 19.5.7
