  <pre><code>let databaseRef = FIRDatabase.database().reference().child("Butikker")
  </code></pre>
  
  <p>When i run this function in viewdidload, my console prints: nil nil</p>
  
  <pre><code>func fetchNearByPlaces() {
      databaseRef.observeSingleEvent(of: FIRDataEventType.value, with: { (snapshot) in
      if let dictionary = snapshot.value as? [String: AnyObject] {
          print(dictionary["Longtitude"], dictionary["Latitude"])
      }
  })
  </code></pre>
