iOS- (`FirebaseApp.configure()` in Swift) before using Firebase Database.'

I was working on a project on xcode in swift and everything was okay with firebase, until I got this error: (FirebaseApp.configure() in Swift) before using Firebase Database.' I'm guessing it happened after I added Auth.auth.currentuser. But the problem is not solved even after I removed the code Auth.auth().cutrent user. I tried replacing the GoogleServices.plist with a new one. But still no luck.

Check to ensure that your database isn't being initialized before using it. If you have the following in your initial view controller:

var ref =  Database.database().reference()

That can cause the error you're describing. Instead, you can use

var ref: DatabaseReference!

and then assign a value when you actually use the reference, or use lazy so the variable isn't instantiated until the first time it's actually used.

lazy var ref = Database.database().ref()

If you're still experiencing the issue, I suggest you create a minimum reproducible code example and then update your question. Without showing any code, this is my best theory.

You need to import Firebase into your AppDelegate.swift file, as well as add FirebaseApp.configure() in the didFinishLaunchingWithOptions method; which is also inside your AppDelegate.swift.

Also, have you made sure that you're opening your .xcworkspace file instead of the .xcodeproj
