import UIKit
import FirebaseDatabase

class HomeViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    // MARK: - variables
    var postDB: DatabaseReference!

    override func viewDidLoad() {
        super.viewDidLoad()

        // getting a node from database //
        postDB = Database.database().reference().child("Posts")

        // observing data changes //
        postDB.observe(DataEventType.value) { (dataSnapshot) in
            self.postArray.removeAll()
            if dataSnapshot.childrenCount > 0 {
                for post in dataSnapshot.children.allObjects as! [DataSnapshot] {
                    let object = post.value as! [String: Any]
                    let description = object["description"] as! String
                    let title = object["title"] as! String
                    let userName = object["username"] as! String
                    let model = postStruct(title: title, description: description, username: userName))
                    self.postArray.append(model)
                }
            }
            self.tableView.reloadData()
        }
    }
}

Try this – the code replaces what you currently have in the snapshot handler.

if let firebaseList = snapshot.children.allObjects as? [FIRDataSnapshot] {
        if let swiftList = snapshot.value as? [String:AnyObject] {
            for firebaseItem in firebaseList {
                let childID = firebaseItem.key as String
                let swiftItem = swiftList[childID]
                let postTitle = swiftItem?["title"] as? String
                let postUsername = swiftItem?["username"] as? String
                let postDesc = swiftItem?["description"] as? String
                let postArray = postStruct(title: postTitle, description: postDesc, username: postUsername)
                self.newPost.insert(postArray, at: 0)
            }
        }
    }
}
