Detox issue: BUILD FAILED Ld build/Build/Products/Debug-iphonesimulator

Question

I'm trying to use Wix/Detox to test my react-native app (the iOS version). I have successfully followed the instructions (up until "detox build") at https://github.com/wix/detox/blob/master/docs/Introduction.GettingStarted.md

However, when running "detox build" in my project directory, I get the following error:

** BUILD FAILED **

The following commands produced analyzer issues:
    Analyze RNFIRMessaging.m
(1 command with analyzer issues)

The following build commands failed:
    Ld build/Build/Products/Debug-iphonesimulator/<myAppName>.app/<myAppName> normal x86_64
(1 failure)
child_process.js:524
    throw err;
    ^

When running "detox test," I get the following error:

I have an e2e folder in my project directory with three files: init.js, mocha.opts, and firstTest.spec.js.

firstTest.spec.js looks like this:

/* eslint-env node, mocha */
/* global element, expect, device, by */

describe('FiestTest', () => {
  beforeEach(async () => {
    await device.reloadReactNative()
  })

  it('Shoudl find the phoneInput field and the init value as "09"', async () => {
    await expect(element(by.id('LoginPage-phoneInput'))).toBeVisible()
    await element(by.id('LoginPage-phoneInput')).typeText('09991234567')
    await expect(element(by.id('LoginPage-loginGuideTxt'))).toBeVisible()
    await element(by.id('LoginPage-loginBtn')).tap()
  })
  it('Dummy1"', async () => {
    await device.reloadReactNative()
  })
  it('Dummy2', async () => {
    await device.reloadReactNative()
  })
  it('Dummy3', async () => {
    await device.reloadReactNative()
  })
})

init.js looks like this:

/* eslint-env node, mocha */

require('babel-polyfill')
const detox = require('detox')
const config = require('../package.json').detox

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

after(async () => {
  await detox.cleanup()
})

And mocha.opts looks like this:

--recursive --timeout 120000 --bail

Your help is highly appreciated!

Answer 1

I ran the following command and it solved the build issue:

watchman watch-del-all; npm start -- --reset-cache

Answer 2

This solved the issue for me:

detox clean-framework-cache && detox build-framework-cache
