End-to-end tests fail on iOS 15.0 with a freshly scaffolded app

[glesperance]

What's going on?
End-to-end tests fail with a freshly scaffolded app. iOS build works, test build works, but the actual run of the tests fails.
When the test suite tries to run, we first see the app open, and then immediately crash, then the tests fails with

detox[99221] ERROR: [DetoxExportWrapper.js/DETOX_INIT_ERROR]
 DetoxRuntimeError: Aborted detox.init() execution, and now running detox.cleanup()

HINT: Most likely, your test runner is tearing down the suite due to the timeout error

    at DetoxAdapterJasmine.beforeEach (/Users/gabriel/Workspace/paltap-io/TestApp/node_modules/detox/runners/jest/DetoxAdapterJasmine.js:19:5)

and then hangs.

Simulator logs give nothing at all.

If we then run the build manually in the simulator it launches without crashing.

To temporarily fix this you can modify your Detox config in package.json:

"detox": {
    "test-runner": "jest",
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/PaltapIOApp.app",
        "build": "xcodebuild -workspace ios/PaltapIOApp.xcworkspace -scheme PaltapIOApp -configuration Debug -sdk iphonesimula
tor -derivedDataPath ios/build -destination 'name=iPhone 11'",
          "type": "ios.simulator",
-         "name": "iPhone 11"
+         "device": { "name": "iPhone 11", "os": "iOS 14.5" }
      },
      "ios.sim.release": {
        "binaryPath": "ios/build/Build/Products/Release-iphonesimulator/PaltapIOApp.app",
        "build": "xcodebuild -workspace ios/PaltapIOApp.xcworkspace -scheme PaltapIOApp -configuration Release -sdk iphonesimulator -derivedDataPath ios/build -destination 'name=iPhone 11'",
        "type": "ios.simulator",
-         "name": "iPhone 11"
+         "device": { "name": "iPhone 11", "os": "iOS 14.5" }
      }
    }

Not sure about closing this though as it is only a workaround until the template is modified to the above, or until Detox is fixed AND updated.

I like the specific configuration setting of device more than name, even if Detox is updated with the fix for Fishhook, which has been merged into master, but not yet released.

Combined with an update to e2e/README.md that provides some guidance for viewing installed simulators and their OS versions in Xcode, this change to the Detox config will fix this issue for freshly ignited apps.
