Angular / Ionic mobile app ios does not fetch from Firebase using angularfire

Question

I am trying to test a little Ionic/Angular sample app on an iOS Emulator.

On the web, all the requests to firestore using angularfire work perfectly fine.

Somehow if I try to execute the same app on the emulator, it keeps loading for the response of the request (if it was a empty response it would say that no results could be retrieved).

What is going on? Do i need to set something specifically for the Emulator to work and perform requests to Firestore?

import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';
import { Capacitor } from '@capacitor/core';
import { initializeAuth, indexedDBLocalPersistence } from 'firebase/auth';
import { getAuth } from 'firebase/auth';

const firebaseApp = initializeApp({
 apiKey: process.env.VUE_APP_FIREBASE_API_KEY,
 authDomain: process.env.VUE_APP_FIREBASE_AUTH_DOMAIN,
 databaseURL: process.env.VUE_APP_FIREBASE_DATABASE_URL,
 projectId: process.env.VUE_APP_FIREBASE_PROJECT_ID,
 storageBucket: process.env.VUE_APP_FIREBASE_STORAGE_BUCKET,
 messagingSenderId: 
 process.env.VUE_APP_FIREBASE_MESSAGING_SENDER_ID,
 appId: process.env.VUE_APP_FIREBASE_APP_ID,
});


function whichAuth() {
  let auth
  if (Capacitor.isNativePlatform()) {
    auth = initializeAuth(firebaseApp, {
      persistence: indexedDBLocalPersistence
    })
  } else {
    auth = getAuth()
  }
  return auth
}

export const auth = whichAuth()
const db = getFirestore();

export const auth = whichAuth();
export { firebaseApp, db };

Then in your component, cal your method like this await signInAnonymously(auth);. Don't forget to import the auth we exported at the top.
