Retrieve child key one by one and display in label swift - swift

Question

I'm trying to retrieve the child in Firebase and print them EACH in a label but when I'm retrieving the key its printing all at the same time. I'm still learning on the go so here's what i tried:
func retrieve(){
let userId = Auth.auth().currentUser?.uid
let intakeRef = Database.database().reference().child("Users").child(userId!).child("Intake")
intakeRef.observeSingleEvent(of: .value, with: { (snapshot) in
if let intake = snapshot.value{
self.ref.child("Attendance").child("Checkin").child(intake as! String).child(userId!).child("BM050-3-3-IMNPD").observe(.value, with: { (snapshot) in
for child in snapshot.children{
let key = (child as AnyObject).key as String
print(key)
label.text = key
}
})
}
}) { (Error) in
print("unable to retrieve name from nameRef")
}
}
The code I tried like i said is printing all at the same time. But i would like to print each one in a separate label. Any help would really be appreciated!

You'll of course need to create a tableViewController and link it up to a TableView and assign your cell its own identifier, but this is a good outline of what you'd need to do in your own tableViewController:
class tableViewController: UITableViewController {
var dataArray = [String]()
var ref = Database.database().reference() //You didn't include your delcaration of ref in your code, so don't use this, just use the one you were already using.
override func viewDidLoad() {
super.viewDidLoad()
retrieve()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataArray.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
let data = dataArray[indexPath.row]
cell.textLabel?.text = data
return cell
}
func retrieve(){
let userId = Auth.auth().currentUser?.uid
let intakeRef = Database.database().reference().child("Users").child(userId!).child("Intake")
intakeRef.observeSingleEvent(of: .value, with: { (snapshot) in
if let intake = snapshot.value{
self.ref.child("Attendance").child("Checkin").child(intake as! String).child(userId!).child("BM050-3-3-IMNPD").observe(.value, with: { (snapshot) in
for child in snapshot.children{
let key = (child as AnyObject).key as String
self.dataArray.append(key)
}
})
self.tableView.reloadData()
}
}) { (Error) in
print("unable to retrieve name from nameRef")
}
}
}
Again you'll need to create your own UItableView, link it up to a UITableViewController, assign your own cell reuse identifier and make sure that cellForRowAt has the correct reuse identifier in it, and you'll need to change the ref variable in my provided code to the ref that you need to use.
