reloadData does not work after fetching data from get method - ios

Question

I have a table and I got my data from a GET method. After I get the data, I would like to use the reloadData function, but it doesn't work and my table does not show anything.
import SwiftyJSON
class NewsTableViewController: UITableViewController {
var ids = [String]()
var titles = [String]()
var descriptions = [String]()
var images = [String]()
var links = [String]()
var dates = [String]()
#IBOutlet var table_news: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
table_news.delegate = self
getNews()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return self.ids.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 0
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:NewsTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: "news_cell") as! NewsTableViewCell
cell.lbl_date.text = self.dates[indexPath.row]
return cell
}

if let results = json.array {
for entry in results {

}
DispatchQueue.main.async{
//print(self.ids.count) it shows 16
self.table_news.reloadData()
}
}
}
}
}

Aren't you returning 0 from numberOfRowsInSection: ? Then, how can the table show anything? :)
