Ionic 4 and Firebase Simulator/Emulator Issues

#1

I am having issues with the emulator/simulator for my Ionic application. For my app, I am using Firebase as the backend. When running the command below, the information from Firebase isn’t showing on the iOS Simulator, but when I use the Ionic Dev App and serve on the browser, the information that is supposed to be retrieved from Firebase is showing. For some reason, when trying to access parts of the application that is suppose to retrieve information from Firebase isn’t showing on the simulator but only on a real device using Ionic Dev App. I really need help as soon as possible.

Command I am using to run simulator:
ionic cordova run ios --livereload

To fix this: make sure you disable the firewall and protection to use the simulator.
