FIrebase iOS integration crash - caused by an invalid GOOGLE_APP_ID

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.

Possibly your GoogleService-Info.plist file is corrupted. Please redownload and replace it.

Hope this helps...

In my case the problem was with the cordova copying GoogleService-Info.plist and corrupting it.

So the solution is you need to do it manually. Just copy your GoogleService-Info.plist from your root folder then go to platforms/ios/project-name/Resources and paste it there and then there is another Resources folder in it paste it there too. platforms/ios/project-name/Resources/Resources

Then again try to make a build or run it in simulator and it'll be working fine.
