FIrebase iOS integration crash - caused by an invalid GOOGLE_APP_ID

Question

I am trying to build my Cordova app with Firebase integrated using Xcode build, but I am getting this vague error, and I can't understand what's wrong. I have placed the GoogleService-Info.plist file in the project directory, but it still fails to build. Here is the stack trace

What could be the problem, I don't know what else to show if it's needed, so please ask.

Answer 1

For some reason Xcode always ignored the GoogleService-Info.plist located in the project root directory, and didn't copied it in the Resources folder of the project.

I manually copied the file there, and then the app compiled and ran just fine.
