Answer 1

Just crash your app once by adding this line --->> crashlytics().crash(); in your startup screen and then just remove this line. It will start working.

Answer 2

TL;DR THIS IS NOT AN ANSWER, JUST A SIMILAR SITUATION

Getting a similar log and the app doesn't crash whatsoever. What OP and I are trying to do I guess is to check if @react-native-firebase/crashlytics is working properly on iOS according to this blog post (taken from official documentation). Some background info:

// Example JS code
import React from "react"
import { Button } from "react-native"
import crashlytics from "@react-native-firebase/crashlytics"

export const App = () => <Button title="Pls crash" onPress={() => { crashlytics().crash() } />

firebase.json configuration file:

{
  "react-native": {
    "android_task_executor_maximum_pool_size": 10,
    "android_task_executor_keep_alive_seconds": 3,
    "crashlytics_debug_enabled": true,
    "crashlytics_disable_auto_disabler": true,
    "crashlytics_auto_collection_enabled": true,
    "crashlytics_is_error_generation_on_js_crash_enabled": true,
    "crashlytics_javascript_exception_handler_chaining_enabled": true
  }
}

Package versions used:

"dependencies": {
    "@react-native-firebase/analytics": "^14.8.0",
    "@react-native-firebase/app": "^14.8.0",
    "@react-native-firebase/crashlytics": "^14.8.0",
    "@react-native-firebase/messaging": "^14.8.0",
    ...
    "react-native": "0.63.4",
}

Error log, while using xcrun simctl spawn booted log stream --level debug --style compact | grep -i crash (after button press):

Expected behaviour: in theory the app should crash and I should see a log in firebase crashlytics console.

Result: nothing happens, like seriously - nothing.

Environment: debug/development, the release version seems to be working fine.

Edit: added expected, result and environment.
