UITableView not loading Firebase Snapshot Data. - ios

Question

I have a Firebase database with structure:
"users"
-uid
- name
- email
. I would like to input the "users" email and name into a UITableviewController tableview in XCode. The data can be seen in my console, but is not appended to my Table View
class DictionaryTableViewController: UITableViewController {
var ref: FIRDatabaseReference!
let cellID = "Cell"
var refHandle: UInt!
var userList = [Users]()
override func viewDidLoad() {
super.viewDidLoad()
//Set firebase database reference
ref = FIRDatabase.database().reference()
//Retrieve posts and listen for changes
refHandle = ref?.child("users").observe(.childAdded, with: { (snapshot) in
//Code that executes when child is added
if let dict = snapshot.value as? [String: AnyObject] {
let user = Users()
user.name = snapshot.childSnapshot(forPath: "name").value as? String
print(user.name)
user.email = snapshot.childSnapshot(forPath: "email").value as? String
print(user.email)
print("databaseHandle was called")
for user in self.userList {
print(user)
self.userList.append(user)
}
self.tableView.reloadData()
}
})
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return userList.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: .subtitle, reuseIdentifier: cellID)
cell.textLabel?.text = userList[indexPath.row].name.self
cell.textLabel?.text = userList[indexPath.row].email.self
return cell
}
}
}

Answer 1

Remove this:
self.tableView.reloadData()
And after the if let statements add this:
DispatchQueue.main.async{
self.tableView.reloadData()
}

Answer 2

Like so; does not show the data on the table still.
//Retrieve posts and listen for changes
func fetchUserData(with completion:#escaping (Bool)->()) {
refHandle = ref?.child("users").observe(.childAdded, with: {
(snapshot) in
//Code that executes when child is added
if (snapshot.value as? [String: AnyObject]) != nil {
let user = Users()
user.name = snapshot.childSnapshot(forPath: "name").value as?
String
print(user.name)
DispatchQueue.main.async{
user.email = snapshot.childSnapshot(forPath: "email").value
as? String
print(user.email)
print("databaseHandle was called")
for user in self.userList {
print(user)
self.userList.append(user)
self.userTable.reloadData()
}
