Display Firebase Data in UITableView - ios

Question

I am trying to make a UITableView display data from my firebase database which is in the following structure
I need the first label to display the shop's name and the shop's type. When I print the values from the database, it displays the list of the shops and the type next to it. However, I am finding it difficult to replicate this into the UITableView. Thank you for the help. Here is my code:
import UIKit
import Firebase
struct shopStruct {
let shopName: String!
let shopType : String!
}
class HomeViewController: UIViewController, UITableViewDataSource , UITableViewDelegate {
#IBOutlet weak var homeTableView: UITableView!
var databaseRef: DatabaseReference!
var shops = [shopStruct]()
override func viewDidLoad() {
super.viewDidLoad()
databaseRef = Database.database().reference()
databaseRef.child("shops").queryOrderedByKey().observe(.childAdded, with: { (snapshot) in
if let valueDictionary = snapshot.value as? [AnyHashable:String]
{
let shopName = valueDictionary["name"]
let shopType = valueDictionary["type"]
self.shops.insert(shopStruct(shopName: shopName, shopType: shopType), at: 0)
self.homeTableView.reloadData()
}
})
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return shops.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let label1 = cell.viewWithTag(1) as! UILabel
label1.text = shops[indexPath.row].shopName
let label2 = cell.viewWithTag(2) as! UILabel
label2.text = shops[indexPath.row].shopType
return cell
}
}

Answer 1

You have to set in viewDidLoad
self.homeTableView.dataSource = self

Answer 2

May be it's not working because you'r reloading the tablebview on secondary thread so could you please replace the code self.homeTableView.reloadData() with following code and try?
DispatchQueue.main.async {
self.homeTableView.reloadData()
}
