Pushing data from Firebase into class object Swift - swift

Question

I have been building my first firebase application and I have run into issues attempting to retrieve data and display it on the map as an annotation.
Currently my logic is as follows : Fetch data and put it into Note Class i then try to push the information into an array which is located in NoteBrain the information appears to be being placed inside the class when i debug with print statements the data shows up. The only issue is i am having trouble pushing the data to the view controller. For some reason my loadallcoordinates is not working, i even try to type print statements and it is not showing up.
My question
Is this the best way to structure my data? Is there any way I can make my current implementation work?
Thankyou
Note Class
import Foundation
import MapKit
class noteClass : NSObject, MKAnnotation{
var title : String?
var subtitle: String?
var coordinate: CLLocationCoordinate2D
var longitude : Double
var latitude : Double
init(dictionary: [String: Any]) {
self.title = dictionary["title"] as? String ?? ""
self.subtitle = dictionary["subtitle"] as? String ?? ""
self.longitude = dictionary["longitude"] as! Double
self.latitude = dictionary["latitude"] as! Double
self.coordinate = CLLocationCoordinate2DMake((dictionary["longitude"] as? Double)!, (dictionary["latitude"] as? Double)!)
}
}
noteBrain or model class
import Foundation
import UIKit
import MapKit
import CoreLocation
import Firebase
import FirebaseDatabase
class noteBrain: UIViewController, CLLocationManagerDelegate{
var noteArray = [noteClass]()
var newNote = false
var outsideToggle = true
let span:MKCoordinateSpan = MKCoordinateSpanMake(0.0025, 0.0025)
var manager = CLLocationManager()
func getNotes() -> Array <noteClass>
{
return noteArray
}
func appendArray(newNote : noteClass){
noteArray.append(newNote)
}
func checkInside( s1 : Int ) -> noteClass{
return noteArray[0]
}
func checkToggle() -> Bool{
return outsideToggle
}
func fetchUser() {
FIRDatabase.database().reference().child("notes").observe(.childAdded, with: { (snapshot) in
if let dictionary = snapshot.value as? [String: AnyObject] {
let user = noteClass(dictionary: dictionary)
self.appendArray(newNote: user)
}
}, withCancel: nil)
}
}
