FirebaseIOS: Use of Undeclared Type 'DatabaseReference'

Question

Sorry for the weird question

Yesterday I had to update my firebase pod, before that everything was fine, but after that, I can't retrieve data anymore

So here's my code

    //  let userID = FIRAuth.auth()?.currentUser?.uid
    var rsef: DatabaseReference! // undeclared

    rsef = Database.database().reference() //. undeclared

I read the official firebase setup instructions, those are right, but I don't know why it says undeclared

For reference, here's my full code

 ref.child("KurdishRsta").child((FIRAuth.auth()?.currentUser?.uid)!).childByAutoId().queryOrderedByKey().observe(.childAdded, with:
        { (snapshot) in
            print("Database\(String(describing: snapshot.value))")
        let value = snapshot.value as? NSDictionary
        let FullRsta1 = value?["Rsta"]
        let FullMeaning1 = value?["Meaning"]





        self.RetrivedRsta.insert(RstasFromFirebase(FullRsta:FullRsta1 as! String ,FullMeaning : FullMeaning1 as! String), at: 0)

        self.tableview.reloadData()



    })
}

the podfile

    Target 'Dictionary' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
   use_frameworks!
   pod 'SDWebImage', '~>3.8'
   pod 'Firebase/Core'
   pod 'Firebase/Auth'
   pod 'Firebase/Storage'
   pod 'Firebase/Database'

Swift Version 5, Firebase (6.5.0), FirebaseAnalytics (6.0.4), FirebaseDatabase (6.0.0)

Follow steps on the Google's Page

Earlier use of import FirebaseDatabase has been removed. Use only import Firebase in a Swift file and to use a database reference a variable can be used as var firebaseDatabaseRef: DatabaseReference!

If the issue persist please try to clean and build a project couple of times or use following commands from the terminal and try to clean and build again.

$pod deintegrate

and then

$pod install

Podfile:

pod 'Firebase/Analytics'
pod 'Firebase/Database'

In my case, git was ignoring Pods directory so pretty much every time I changed branch I had to run pod install command (minor changes on the configurations).

In one of those changes I started getting this error. I tried cleaning build folder, delivery data folder, restart, and none worked until I delete the content of Pods directory and run pod install.
