import UIKit

import Firebase

var pdej: Int16 = 0
var boiss: Int16 = 0
var bouche: Int16 = 0
var conser: Int16 = 0
var rfrai: Int16 = 0
var patis: Int16 = 0
var fleg: Int16 = 0
var epice: Int16 = 0
var fecul: Int16 = 0
var hyent: Int16 = 0
var sauc: Int16 = 0

class ViewController: UIViewController {

var ref:FIRDatabaseReference!
var refHandle: UInt!

override func viewDidLoad() {
super.viewDidLoad()

// Do any additional setup after loading the view, typically from a nib.

    ref = FIRDatabase.database().reference()
    self.ref.child("pListe").observeSingleEvent(of: .value, with: { (snapshot) in
        
            if let result = snapshot.children.allObjects as? [FIRDataSnapshot] {
                for child in result {
                    //do your logic and validation here
                    
                    var PDEJ = child.key 
                    print(PDEJ)                                        // print my solution
            }
            } else {
                       print("no results")
                      }
        }) { (error) in
            print(error.localizedDescription)
        }

}

There you can read my FirDatabase :

listecourse-97211
!
!_ pListe : !- boiss : 10
!- bouche : 110
!- conser : 120
!- epice : 133

!- fleg : 154
!- hyent : 161
!- patis : 172
!- pdej : 189
!- rfrai : 111
!- sauc : 151

variable B = value ( “boiss”)
variable C = value ( “10”)
