Detox: Hangs on `Searching for device matching iPhone 7...`

[sam-n-johnston]

Description

I'm unable to get detox to launch the simulator. When I follow all the installation instructions, it shows the following text and then hangs forever. But I have an iPhone 7 simulator open and ready.

Searching for device matching iPhone 7...

So I downloaded the react-native-detox-example and it works correctly (so it isn't a problem with the programs installed with brew). I copied the detox config and test, but I still couldn't get it to work. But when I delete the yarn.lock and then yarn again, the react-native-detox-example gets the same problem as my app. So I assume it's a package (or package version) problem, but I can't figure it out. Maybe someone can shed some light on this?

Steps to Reproduce

Install react-native-detox-example
Remove yarn.lock
yarn
yarn test-e2e

I had the same issue few hours ago but this #304 seems to be resolving problem. Just update/reinstall applesimutil.

This doesn't solve it for me. I installed applesimutil for the first time today. I just tried to uninstall and reinstall, but it still doesn't work.

Please provide a verbose detox log to further investigate this issue

I'm facing a similar issue with my detox tests. I'm getting this error:

1)  "before all" hook:
     Error: Can't find a simulator to match with 'iPhone 7', run 'fbsimctl list' to list your supported devices.
It is advised to only state a device type, and not to state iOS version, e.g. 'iPhone 7'

I've tried updating applesimutil but I'm still getting the same error. Any ideas?

@alex-blair , seems like you are using a pre Detox 5.8.0 version, update your library and see if it helps

Thanks @rotemmiz - that fixed it! 🎉

"detox": "^6.0.2", still encounter this problem.
I solve it with detox clean-framework-cache && detox build-framework-cache
