arrays - Retrieve image from firebase storage to show on tableView (Swift)

Question

Extension question from New Firebase retrieve data and put on the tableView (Swift)

By moving the Firebase code to viewDidLoad, all the text part of Post can show curretly. But I still can't put the image to the tableView. I have check the images retrieving and it was success, I suppose that the images I retrieve from Firebase was't in the post array.

this is my fix code:

  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()
    let userPostRef = self.databaseRef.child("posts")
    userPostRef.queryOrderedByChild("time").observeEventType(.ChildAdded, withBlock: {(snapshot) in
        if let postAdd  = snapshot.value as? NSDictionary{

            let url = snapshot.value?["postPhoto"] as! String
            let userPhotoUrl = snapshot.value?["userPhoto"] as! String
            let myPost = Post(data: postAdd)

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

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

            self.posts.insert(myPost, atIndex: 0)
            self.tableView.reloadData()

        }




})

}
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 {
    return posts.count


}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellIdentifier = "postCell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath)as! timelineTableViewCell
    //Dispatch the main thread here
    dispatch_async(dispatch_get_main_queue()) {
        cell.usernameLabel.text = self.posts[indexPath.row].username
        cell.postText.text = self.posts[indexPath.row].postText
        cell.timeLabel.text = self.posts[indexPath.row].time
        cell.postPhoto.image = self.posts[indexPath.row].postPhoto
        cell.userPhoto.image = self.posts[indexPath.row].userPhoto


    }
    return cell
   }
   }

And my struct of Post hope it might help!

struct  Post {
var username: String?
var postText: String?
var time: String?
var userPhoto: UIImage?
var postPhoto: UIImage?
var url: String?
var userPhotoUrl:String?
init(data: NSDictionary) {
   username = data["username"] as? String
   postText = data["postText"] as? String
    time = data["time"]as? String
    userPhoto = data["userPhoto"] as? UIImage
    postPhoto = data["postPhoto"] as? UIImage
    url = data["postPhoto"] as? String
    userPhotoUrl = data["userPhoto"] as? String
}

}

Hope can get some advice!
