Detox: detox test stuck at Searching for device matching iPhone <model>

My project is built successfully, but when I run detox test, I get the bellow error at the stage Searching for device matching iPhone <model>. I've changed the iPhone models in my package.json, but the error remains the same.

I'm using
detox 5.6.2
react-native: 0.44.0

I have the following in my package.json:

"detox": {
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/<my-app>.app",
        "build": "xcodebuild -project ios/<my-app>.xcodeproj -scheme <my-app> -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "name": "iPhone 6s"
      }
    }
  }

please update applesimutil to latest version!
There has been breaking change in the way we filter and output the device list. Detox should have handled that by showing a more explicit error, suggesting to update applesimtutils, but clearly, it doesn't work.

@rotemmiz yep! That absolutely resolved the issue for me!
And as mentioned in #127, it is a good idea for Detox to produce more transparent errors.
Thank you.

For anyone else like me who had forgotten where applesimutils comes from... it's probably homebrew.

brew update && brew upgrade applesimutils
