Firebase Geofire centre map on location from database - swift

Question

So I have multiple locations stored in my database, using Geofire. I want to centre the map on a specific one.
I want to know if it is possible to access the firebase database to only retrieve the coordinates saved by GeoFire as a variable so that I can create a CLLocation and centre the map on this one location. Here is my code.
I call getJobLocation in my viewDidLoad. This is where I want to grab the job coordinates from Firebase and then call the other methods i.e. showJobsOnMap using these coordinates
func getJobLocation(jobID: String) {
...
}
func centreMapOnLocation(location: CLLocation) {
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate, 2000, 2000)
mapView.setRegion(coordinateRegion, animated: true)
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
let annoIdentifier = "job"
var annotationView: MKAnnotationView?
if annotation.isKind(of: MKUserLocation.self) {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "User")
annotationView?.image = UIImage(named:"currentLocationPin")
} else if let deqAnno = mapView.dequeueReusableAnnotationView(withIdentifier: "job") {
annotationView = deqAnno
annotationView?.annotation = annotation
} else {
let MKAV = MKAnnotationView(annotation: annotation, reuseIdentifier: annoIdentifier)
MKAV.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
annotationView = MKAV
}
if let annotationView = annotationView, let _ = annotation as? JobAnnotation {
let postsRef = self.dataBaseRef.child("jobs")
postsRef.observe(.value, with: { (posts) in
for _ in posts.children {
annotationView.canShowCallout = true
annotationView.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
annotationView.image = UIImage(named: "jobPin")
}
})
}
return annotationView
}
func showJobsOnMap(location: CLLocation) {
let circleQuery = geoFire!.query(at: location, withRadius: 2.5)
_ = circleQuery?.observe(GFEventType.keyEntered, with: { (key, location) in
if let key = key, let location = location {
if key == self.job.postID {
let postsRef = self.dataBaseRef.child("jobs").child(key)
postsRef.observe(.value, with: { (posts) in
for _ in posts.children {
let post = Post(snapshot: posts )
let jobDate = post.postDateTime
let price = post.price
let anno = JobAnnotation(coordinate: location.coordinate, jobID: key, jobDate: jobDate, title: "£\(price) - \(jobDate)")
self.mapView.addAnnotation(anno)
}
})
}
}
})
}
