iOS Swift appending value to array

Question

My Question is very simple,

I'm Learning iOS development and I'm stuck with tableviewcontroller

I can add Values to tableview with array, but when I try to append value from Parse, it's not working.

Here is the code:

var names: [String] = ["Name_one", "Name_two"]
let query: PFQuery! = PFUser.query()

override func viewDidLoad() {
    super.viewDidLoad()

    query.whereKey("objectId", notEqualTo: PFUser.currentUser()!.objectId!)

    query.findObjectsInBackgroundWithBlock { objects, error in
        if (error == nil) {
            for user: PFUser in (objects as! [PFUser]) {


            self.names.append(user.username as! String)

            }
        } else {
            print("Error")
        }
    }

there is no error, it's just that the value doesn't get appended to the array — Akshaye JH

You must to reload your tableview after get data finished

Code:

query.findObjectsInBackgroundWithBlock { objects, error in
    if (error == nil) {
        for user: PFUser in (objects as! [PFUser]) {


        self.names.append(user.username as! String)

        }
        yourTableview.reloadData()
    } else {
        print("Error")
    }
}

How can I know, what's the name of my TableView? sry I'm really stuck at basics

OOP@@ i don't know, this is your uitableview. if you use UItableviewController so it is self.tableview. If you add UITableview to UIViewController , it 's outlet of tableview in storyboard

so do I need to add self.tableview.reloadData() ??
