ios – Database.database() Error cannor discover in scope>

I’m attempting to delete a desk view cell in swift and once I delete the cell I additionally have to delete the info in firebase. So I take advantage of Database.database().baby("tweet") that is the place the error is it says can not fin Database in scope.

import UIKit
import Firebase
import Firestore
class TableViewController: UITableViewController {
    
    var db:Firestore!
    var tweetArray = [tweet]()
   
    override func viewDidLoad() {
        tremendous.viewDidLoad()
        tableView.allowsMultipleSelectionDuringEditing = true
        db = Firestore.firestore()
        loadData()
        checkForUpdates()
    }
    override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }
    
    override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
        

Database.database().baby("tweet")    "Error can not discover Database in scope"
    }
    
    func loadData() {
        db.assortment("tweet").getDocuments() {
            querySnapshot, error in
            if let error = error {
                print("(error.localizedDescription)")
            }else{
self.tweetArray = querySnapshot!.paperwork.compactMap({tweet(dictionary: $0.information())})
                DispatchQueue.most important.async {
                    self.tableView.reloadData()
                }
            }
        }
    }
   
    func checkForUpdates() {
        db.assortment("tweet").whereField("timeStamp", isGreaterThan: Date())
            .addSnapshotListener {
                querySnapshot, error in
                guard let snapshots = querySnapshot else {return}
                
                snapshots.documentChanges.forEach {
                    diff in
                    
                    if diff.sort == .added {
                    self.tweetArray.append(tweet(dictionary: diff.doc.information())!)
                        DispatchQueue.most important.async {
                            self.tableView.reloadData()
                        }
                    }
                }
            }
        
    }
    
    @IBAction func composeSweet(_ sender: Any) {
        
        let composeAlert = UIAlertController(title: "Add Worker", message: "Add Worker", preferredStyle: .alert)
        
        composeAlert.addTextField { (textField:UITextField) in
            textField.placeholder = "Identify"
        }
        
        composeAlert.addTextField { (textField:UITextField) in
            textField.placeholder = "Adress"
        }
    
        
        composeAlert.addAction(UIAlertAction(title: "Cancel", type: .cancel, handler: nil))
        
        composeAlert.addAction(UIAlertAction(title: "Add Worker", type: .default, handler: { (motion:UIAlertAction) in
            
            if let identify = composeAlert.textFields?.first?.textual content,
               let content material = composeAlert.textFields?.final?.textual content {
                let newTweet = tweet(identify: identify, content material: content material,timeStamp: Date())
                
                var ref:DocumentReference? = nil
            
                ref = self.db.assortment("tweet").addDocument(information: newTweet.dictionary) {
                    error in
                    
                    if let error = error {
                        print("Error including doc: (error.localizedDescription)")
                    }else{
                        print("Doc added with ID: (ref!.documentID)")
                    }
                }
            }
        }))
        
        self.current(composeAlert, animated: true, completion: nil)
    }

    // MARK: - Desk view information supply

    override func numberOfSections(in tableView: UITableView) -> Int {
        
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection part: Int) -> Int {
        
        return tweetArray.depend

    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)

        let tweet1 = tweetArray[indexPath.row]
        cell.textLabel?.textual content = "(tweet1.identify) (tweet1.content material)"
        cell .detailTextLabel?.textual content = "(tweet1.timeStamp) "
        

        return cell
    }
}

I attempted importing completely different firebase imports and that did not work i am unsure if it has one thing to do with my cocoa pods. these are the cocapods I’ve downloaded: pod ‘Firebase/Core
pod ‘Firebase/Auth’ pod ‘Firestore’
