'FirebaseApp instance may not be nil. Use FirebaseApp.app() if you'd like to use the default FirebaseApp instance.' Second app in react native for iOS

So, I worked on my react native app while running android emulators for a while, and during that time, I had initialized a second firebase app using @react-native-firebase/app other than my main one which is working fine on both android and iOS. I was fully capable of using the second app I had initialized, but then I began to run it on an iOS simulator and that's when things went downward and I got this error: FirebaseApp instance may not be nil. Use FirebaseApp.app() if you'd like to use the default FirebaseApp instance. whenever I tried to fetch a document and I still haven't been able to fix. I tried logging the second app using console.log(firebase.app('appName') and it would show me all the correct methods and variables so it wasn't undefined. I don't want to add another Google-services.plist file, since that would mess up my analytics. does anyone have any idea as to how I could solve this?
