Swift: Retrieve data from Firebase Database to label - swift

Question

I'm trying to get my data from Firebase Database to particular label in Swift. I have two labels in TableView (as Main.storyboard) tagged 1 and 2.
In a ViewController, I have this code:
import UIKit
import Firebase
import FirebaseDatabase
struct confStruct {
let title : String!
let place : String!
}
class EVS_Table_VC: UITableViewController {
var conf = [confStruct]()
override func viewDidLoad() {
super.viewDidLoad()
let databaseRef = FIRDatabase.database().reference()
databaseRef.child("conferences").queryOrderedByKey().observeEventType(.ChildAdded, withBlock: {
snapshot in
self.tableView.reloadData()
})
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return conf.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell")
let label1 = cell?.viewWithTag(1) as! UILabel
label1.text = conf[indexPath.row].title
let label2 = cell?.viewWithTag(2) as! UILabel
label2.text = conf[indexPath.row].place
return cell!
}
}
But nothing shows up in a Simulator. Does somebody have a proposition how to resolve this? This struct confStruct initializes my variable from
Database? (title, place).
JSON tree:
"conferences": {
"Key": {
"date": "some date"
"deadline": "some deadline"
"place": "some place"
"title": "some title"
}
}

Answer 1

Change your struct to :-
struct confStruct {
let title : String!
let place : String!
init(title_String : String!, place_String : String!){
self.title = title_String
self.place = place_String
}
}
And:-
FIRDatabase.database().reference().child("conferences/Key").observeSingleEvent(of: .value, with: {(snap) in
if let snapDict = snap.value as? [String:AnyObject]{
let titleS = snapDict["title"] as! String
let placeS = snapDict["place"] as! String
let temp = confStruct.init(title_String: titleS, place_String: placeS)
self. conf.append(temp)
self.tableView.reloadData()
}
})
