Criei uma mídia social simples com o novo Firebase e salvei com êxito as strings no banco de dados e as imagens no armazenamento, mas quando se trata de recuperar dados de volta à tabelaVer as coisas incomuns acontecem!

todas as imagens recuperadas aparecem aleatoriamente e mudam continuamente, mas outra parte aparece perfeitamente ou quando eu uso as mensagens de retorno. tableView não mostra nenhuma postagem.

Espero que alguém possa gentilmente me dar alguma sugestão

    import UIKit
    import Firebase
    import FirebaseStorage

class timelineTableViewController: UITableViewController {
var posts = [Post]()
var databaseRef: FIRDatabaseReference!
var storageRef: FIRStorageReference!

override func viewDidLoad() {
    super.viewDidLoad()
    databaseRef = FIRDatabase.database().reference()
    storageRef = FIRStorage.storage().reference()

}


override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return posts.count

}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellIdentifier = "postCell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath)as! timelineTableViewCell

    let userPostRef = self.databaseRef.child("posts")
    userPostRef.observeEventType(.ChildAdded, withBlock: {(snapshot) in
        if let postAdd  = snapshot.value as? NSDictionary{
            let myPost = Post(data: postAdd)
            self.posts.insert(myPost, atIndex:0)

            cell.usernameLabel.text = self.posts[indexPath.row].username
            cell.postText.text = self.posts[indexPath.row].postText
            cell.timeLabel.text = self.posts[indexPath.row].time
            let url = snapshot.value?["postPhoto"] as! String
            let userPhotoUrl = snapshot.value?["userPhoto"] as! String

            FIRStorage.storage().referenceForURL(url).dataWithMaxSize(10 * 1024 * 1024, completion: { (data, error) in
                let postPhoto = UIImage(data: data!)
                cell.postPhoto.image = postPhoto
                FIRStorage.storage().referenceForURL(userPhotoUrl).dataWithMaxSize(10 * 1024 * 1024, completion: { (data, error) in
                    let userPhoto = UIImage(data: data!)
                    cell.userPhoto.image = userPhoto

                })




        })
        }
    })

        return cell
    }

    }
