applesimutils --list returns empty list [] after MacOS Mojave and Xcode 11.3 update - detox

Question

Describe the bug
After upgrading my MacOS from High Sierra to Mojave and Xcode from 10.x to 11.3, I'm no longer able to run the Detox test.. It gives me this error below about not having iOS simulators.
**DetoxRuntimeError: Failed to find a device by UDID = "7C50BE35-0CDE-413A-A08D-784E98C61010" and by type = "iPhone 11 Pro"
HINT: Run 'applesimutils --list' to list your supported devices. It is advised only to specify a device type, e.g., "iPhone Xʀ" and avoid explicit search by OS version.
at SimulatorDriver._queryDevices (../node_modules/detox/src/devices/drivers/SimulatorDriver.js:224:13)**
So I ran applesimutils --list command and received empty list like below.

But if I run xcrun simctl list devices then I get the list of devices pertaining to iOS 13.3
To Reproduce
[Yes] I have tested this issue on the latest Detox release and it still reproduces
Provide the steps necessary to reproduce the issue. If you are seeing a regression, try to provide the last known version where the issue did not reproduce.
Upgrade MacOS from High Sierra to Mojave and Xcode from 10.x to 11.3 (latest)
Run "detox text"
Got this error
DetoxRuntimeError: Failed to find a device by UDID = "7C50BE35-0CDE-413A-A08D-784E98C61010" and by type = "iPhone 11 Pro"

But if I run xcrun simctl list devices then I get the list of devices pertaining to iOS 13.3. I even changed my package.json to reflect the latest migration guide link below and included the device object - https://github.com/wix/Detox/blob/master/docs/Guide.Migration.md
This is how my package.json looks like
"detox": {
"configurations": {
"ios.sim.debug": {
"type": "ios.simulator",
"binaryPath": "build/native/QuickSightiOS-2.0.2096.d.d.app",
"build": "xcodebuild -project ios/quicksight-react-native-mobile-tests.xcodeproj -scheme quicksight-react-native-mobile-tests -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
"device": {
"type": "iPhone 11 Pro",
"id": "7C50BE35-0CDE-413A-A08D-784E98C61010"
}
}
},
"test-runner": "jest"
},`
I went to this website https://github.com/wix/AppleSimulatorUtils and reran the applesimutils commands again..
brew tap wix/brew
brew install applesimutils
After running the 2nd command above, i got this error
**4c32759b84a9:QuicksightReactNativeMobileTests kondurc$ brew install applesimutils

Expected behavior
I would expect applesimutils --list command to show the list of simulators supported and eventually my detox test to run successfully instead of complaining about failing to find the device type.

As stated in the readme:
https://github.com/wix/AppleSimulatorUtils#troubleshooting
If Homebrew complains about a conflict in the wix/brew tap, run brew untap wix/brew && brew tap wix/brew and try installing again
Then upgrade applesimutils normally.
