Swift GoogleMaps fitBounds Zoom - swift

Question

New coder try to fit GoogleMap in my view.
I have searched a lot of information and I have come to this conclusion, but it does not work for me.
override func loadView() {
var markerList = [GMSMarker]()
// Create a GMSCameraPosition
let camera = GMSCameraPosition.camera(withLatitude: 4.390205, longitude: 2.154007, zoom: 8)
let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
mapView.isMyLocationEnabled = true
view = mapView
mapView.settings.myLocationButton = true
//mapView.setMinZoom(10, maxZoom: 20)
//create markers
for loc in arrayOfMapStops {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: loc.lat, longitude: loc.long)
marker.title = loc.address
marker.snippet = loc.type
if loc.type == "Entrega" {marker.icon = GMSMarker.markerImage(with: .green)}
else {marker.icon = GMSMarker.markerImage(with: .blue)}
marker.map = mapView
markerList.append(marker)
}
//fit map to markers
var bounds = GMSCoordinateBounds()
for marker in markerList {
bounds = bounds.includingCoordinate(marker.position)
}
let update = GMSCameraUpdate.fit(bounds)
mapView.moveCamera(update)
}
The map is not adjusted with the proper zoom.
Anyone can help me with the zoom issue?
Thanks in advance :)

I solved the problem by myself. I use DispatchQueue to set the right zoom to my map.
Here is my final code:
override func loadView() {
var markerList = [GMSMarker]()
// Create a GMSCameraPosition
let camera = GMSCameraPosition.camera(withLatitude: 40.4167 , longitude: -3.70325, zoom: 8)
let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
mapView.isMyLocationEnabled = true
view = mapView
mapView.settings.myLocationButton = true
//mapView.setMinZoom(10, maxZoom: 20)
//create markers
for loc in arrayOfMapStops {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: loc.lat, longitude: loc.long)
marker.title = loc.address
marker.snippet = loc.type
if loc.type == "Entrega" {marker.icon = GMSMarker.markerImage(with: .green)}
else {marker.icon = GMSMarker.markerImage(with: .blue)}
marker.map = mapView
markerList.append(marker)
}
delay(seconds: 3) { () -> () in
//fit map to markers
var bounds = GMSCoordinateBounds()
for marker in markerList {
bounds = bounds.includingCoordinate(marker.position)
}
let update = GMSCameraUpdate.fit(bounds, withPadding: 100.0)
mapView.animate(with: update)
}
}
func delay(seconds: Double, completion:#escaping ()->()) {
let when = DispatchTime.now() + seconds
DispatchQueue.main.asyncAfter(deadline: when) {
completion()
}
}
