Error: Can't find a simulator to match with "iPhone 7"

[matt-paul]

Describe the bug
Detox can't find the simulators.

To Reproduce

1. Run detox test

2. Run xcrun simctl list to verify available simulators.

My package.json configuration.

 "detox": {
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/myapp.app",
        "build": "xcodebuild -workspace ios/myapp.xcworkspace -scheme myapp -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build -UseModernBuildSystem=NO",
        "type": "ios.simulator",
        "name": "iPhone 7"
      }
    }

config.json

{
  "setupFilesAfterEnv": ["./init.js"],
  "testEnvironment": "node"
}

init.js

const detox = require('detox');
const config = require('../package.json').detox;
const adapter = require('detox/runners/jest/adapter');

jest.setTimeout(120000);
jasmine.getEnv().addReporter(adapter);

beforeAll(async () => {
  await detox.init(config);
});

beforeEach(async () => {
  await adapter.beforeEach();
});

afterAll(async () => {
  await adapter.afterAll();
  await detox.cleanup();
});

Expected behaviour
Detox should find the simulator and run the test(s). Please note that I am fairly new to React Native development and so perhaps there is something simple i am missing here.

Screenshots

Environment

• Detox: 12.1.0
• React Native: 0.59.2
• Node: 11.12.0
• Device: iPhone 7
• Xcode: 10.2(10E125)
• macOS: 10.14.4

Detox uses apple�simutils for finding devices.

Try running applesimutils --list --byName "iPhone 7".

Most likely, you need to upgrade `applesimutils.

@LeoNatan The result of that command was an empty array, so i have upgraded and now back up again. Strange, I am not sure how this occurred as detox was happy until (i believe) i updated Xcode, however there may well be some user error involved at some point. 🤔 Thank you for your quick response.

Sure
