Testing e2e with detox failing to start iPhone simulator, starts Apple TV instead

Question

tldr; I have a React Native app, and I am using workspace. I have gone through this detox getting started document and I now have an e2e folder with 3 files (default), and a configuration in the package.json.

Configuration looks like

"detox": {
    "test-runner": "mocha",
    "specs": "e2e",
    "runner-config": "e2e/mocha.opts",
    "configurations": {
        "ios.sim.debug": {
            "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/MyApp.app",
            "build": "xcodebuild -workspace ios/MyApp.xcworkspace -scheme Staging -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
            "type": "ios.simulator",
            "name": "iPhone 6"
        }
    }
}

When I run xcrun simctl list I get the following list, where iPhone 6 is listed and Booted.

== Devices ==
-- iOS 11.4 --
    iPhone 5s (E9D0264C-9257-4BE4-8693-4B7AE6AAE97A) (Shutdown)

detox build --configuration ios.sim.debug runs fine, but when I run detox test --configuration ios.sim.debug or detox build or detox build --reuse it starts the Apple TV simulator and throws this error

You can see that under detox info 5: it starts booting up 9875527D-A6FC-4BD8-965E-255C910E3ABA, which is the Apple TV Device.

How can I configure detox to start an iPhone simulator instead?

brew update && brew upgrade applesimutils and detox clean-framework-cache && detox build-framework-cache as suggested by Tim Rijavec helped in my case! Hidden in the comments it looked like there is no solution to this issue.
