TableView events not being added from firebase - ios

Question

I am trying to update values in a tableView value from firebase. The values are being put in the array while in the observe closure, but afterwards, it remains 0, this makes sense because it is asynchronous (correct me if I am wrong). However, this has worked before in previous tableView, so I am not sure what the problem is. This is the code:
let id = Auth.auth().currentUser?.uid
Database.database().reference().child("users").child(id!).child("createdEvents").observe(.value) { snapshot in
//self.eventsArray.removeAll()
let ref = Database.database().reference().child("users").child(id!).child("createdEvents")
ref.observe(.value) { snapshot in
print("start")
print(snapshot.childrenCount)
let enumerator = snapshot.children
while let rest = enumerator.nextObject() as? DataSnapshot {
self.eventsArray.append(rest.key as! String)
}
Database.database().reference().child("Events").observe(.value) { (data) in
let events = data.value as! [String:[String:Any]]
for(_,value) in events{
print(self.eventsArray)
if(self.eventsArray.contains(value["EventName"]! as! String)){
self.actualEvents.append(AdminEvents(evName: value["EventName"]! as! String, evDesc: value["EventDescription"]! as! String, evStartDate: value["start time"]! as! String, evEndDate: value["end time"] as! String, evNumPeople: value["NumberOfPeople"]! as! Int, evNumRegistered: value["currentPeople"] as! Int))
}
}
print("Actual events array " + "\(self.actualEvents)")
}
}
self.tblEvents.reloadData()
}
And it prints out the values that I want it to when I tests it.
The end objective here is to go into the users createdEvents and print eventTest and eventTest1 to the tableView, but no values inside there.
Edit: I forgot to add the events firebase structure, it does exist.

I don't see any child in your DB with "Events" name.
Database.database().reference().child("Events").observe(.value) { (data) in

Answer 2

Ok I fixed it. For those wondering, I simply just deleted the observe closure around this part, because I realized that the first part was already doing that.
let ref = Database.database().reference().child("users").child(id!).child("createdEvents")
ref.observe(.value) { snapshot in
print("start")
print(snapshot.childrenCount)
let enumerator = snapshot.children
while let rest = enumerator.nextObject() as? DataSnapshot {
self.eventsArray.append(rest.key as! String)
}
Here is the new code:
Database.database().reference().child("users").child(id!).child("createdEvents").observe(.value) { snapshot in
//self.eventsArray.removeAll()
print("start")
print(snapshot.childrenCount)
let enumerator = snapshot.children
while let rest = enumerator.nextObject() as? DataSnapshot {
self.eventsArray.append(rest.key as! String)
}
Database.database().reference().child("Events").observe(.value) { (data) in
let events = data.value as! [String:[String:Any]]
for(_,value) in events{
print(self.eventsArray)
if(self.eventsArray.contains(value["EventName"]! as! String)){
self.actualEvents.append(AdminEvents(evName: value["EventName"]! as! String, evDesc: value["EventDescription"]! as! String, evStartDate: value["start time"]! as! String, evEndDate: value["end time"] as! String, evNumPeople: value["NumberOfPeople"]! as! Int, evNumRegistered: value["currentPeople"] as! Int))
}
}
print("Actual events array " + "\(self.actualEvents)")
}
self.tblEvents.reloadData()
}
self.tblEvents.dataSource = self
self.tblEvents.delegate = self
}
