custom Google Maps blue dot in Swift - swift

Question

What I want to achieve is to customize google maps blue dot with an svg icon,
with the icon moving when location is changed.
what I am doing:
struct GoogleMapsView: UIViewRepresentable {
#ObservedObject var locationManager = LocationManager.shared
#State var myLocationDot = GMSMarker()
#Binding var nearbyDrivers: [NearbyDriver]
init(nearbyDrivers: Binding<[NearbyDriver]>){
self._nearbyDrivers = nearbyDrivers
myLocationDot.position = locationManager.userLocation!.coordinate
}
func makeUIView(context: Context) -> GMSMapView {
let camera = GMSCameraPosition.camera(withLatitude: locationManager.userLocation!.coordinate.latitude, longitude: locationManager.userLocation!.coordinate.longitude, zoom: 15)
let mapView = GMSMapView(frame: CGRect.zero, camera: camera)
myLocationDot.position = CLLocationCoordinate2D(latitude: locationManager.userLocation!.coordinate.latitude, longitude: locationManager.userLocation!.coordinate.longitude)
let myLocationDotIcon = UIImage(named: "myLocationDotIcon.svg")
let myLocationDotIconImage = UIImageView(image: myLocationDotIcon!)
myLocationDotIconImage.frame = CGRect(x: 0, y: 0, width: 40, height: 50)
myLocationDot.iconView = myLocationDotIconImage
myLocationDot.zIndex = 1
myLocationDot.map = mapView
// MARK: - Load nearby drivers
if !nearbyDrivers.isEmpty {
for driver in nearbyDrivers {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: driver.location.lat, longitude: driver.location.long)
let locationIcon = UIImage(named: "carAnnotation.png")
let locationIconImage = UIImageView(image: locationIcon!)
locationIconImage.frame = CGRect(x: 0, y: 0, width: 24, height: 24)
marker.iconView = locationIconImage
marker.zIndex = 0
marker.map = mapView
}
}
//MARK: - MapStyle
do {
if let styleURL = Bundle.main.url(forResource: "style", withExtension: "json") {
mapView.mapStyle = try GMSMapStyle(contentsOfFileURL: styleURL)
} else {
NSLog("Unable to find style.json")
}
} catch {
NSLog("One or more of the map styles failed to load. \(error)")
}
return mapView
}
func updateUIView(_ uiView: GMSMapView, context: Context) {
uiView.isMyLocationEnabled = false
}
func makeCoordinator() -> Coordinator {
Coordinator(myLocationDot: $myLocationDot, owner: self)
}
class Coordinator: NSObject, GMSMapViewDelegate, CLLocationManagerDelegate {
#ObservedObject var locationManager = LocationManager.shared
#Binding var myLocationDot: GMSMarker
let owner: GoogleMapsView
init(myLocationDot: Binding<GMSMarker>, owner: GoogleMapsView) {
self.owner = owner
_myLocationDot = myLocationDot
}
func didTapMyLocationButton(for mapView: GMSMapView) -> Bool {
mapView.animate(toLocation: locationManager.userLocation!.coordinate)
return true
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
myLocationDot.position = locations.last!.coordinate
}
}
}
The idea is that I need to change the blue dot appearance but leave the functionalities as they need to be.
For some reason I can't find any course on advanced google maps customization. if you could refer a guy that does the thing, that would be awesome.
