Sounds like you've lost your GoogleServiceInfo.plist file...

[Jonovono]

@chrisbianca it's definitely there! And removed and re-added it and everything and still getting the error.

[Jonovono]

It's strange though, it seems to happen once, and then I reload the app and it works fine.

[chrisbianca]

I'm sorry, but this is definitely going to be something to do with your project setup. We've not had any other issues like this flagged since releasing v4. I'd imagine it's your Xcode workspace getting itself in a bit of a pickle.

I'm going to close as it's not going to be a react-native-firebase issue.

It is recommended to add the line within the method BEFORE creating the RCTRootView. Otherwise the initialization can occur after already being required in your JavaScript code - leading to app not initialised exceptions.

Error: The [[DEFAULT]] firebase app has not been initialized! i am getting this error only on ios ..any one please help me to resolve this issue.thank you

At the beginning of the didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method add the following line:
[FIRApp configure];

It is recommended to add the line within the method BEFORE creating the RCTRootView. Otherwise the initialization can occur after already being required in your JavaScript code - leading to app not initialised exceptions.
