How do I get tableview cell to populate from bottom to top?

Question

I want to make the cells start from the bottom going up on the tableview. It is currently going from top to bottom. I am retrieving the data from firebase. How do I make it go otherwise (reverse it). Thanks!

var posts = [postStruct]()



override func viewDidLoad() {
    super.viewDidLoad()


    let ref = FIRDatabase.database().reference().child("Posts")

    ref.observeSingleEvent(of: .value, with: { snapshot in

        print(snapshot.childrenCount)

        for rest in snapshot.children.allObjects as! [FIRDataSnapshot] {

            guard let value = rest.value as? Dictionary<String,Any> else { continue }

            guard let  title = value["Title"] as? String else { continue }

            let post = postStruct(title: title)

            self.posts.append(post)

        }

        self.tableView.reloadData()
    })
}




override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return posts.count
}

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

    let label1 = cell?.viewWithTag(1) as! UILabel
    label1.text = posts[indexPath.row].title
    return cell!
}

}

With `reversed`? For example, `self.posts = self.posts.reversed(); self.tableView.reloadData()` — But to be honest, it is quite unclear what you are asking to do, so perhaps that isn't it (whatever "it" is). — matt, May 07 '17 at 18:53

Try this :

self.posts.reversed().forEach {
    print($0)
}
