How to focus on a specific location by using google maps.

Asim Gunduz

Hi, I want to pass coordinates from FirstVC to my SecondVC. and inside the SecondVC which holds MyMap I want the map to show the coordinates I've sent from the FirstVC to do this Here is what I did. SecondVC

override func viewDidLoad() {
super.viewDidLoad()

//Mapview Settings.
self.MyMapView.delegate = self
self.MyMapView.isMyLocationEnabled = true
self.MyMapView.settings.myLocationButton = true

}

I have this Function

func InitGoogleMaps(pMyMapInf:MyMapInf){

if (pMyMapInf.IsEmpty)
{
    return
}

let camera = GMSCameraPosition.camera(withLatitude: pMyMapInf.MyDestinLongitute, longitude: pMyMapInf.MyDestinLongitute, zoom: 6.0)
let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
MyMapView = mapView
MyMapView.isMyLocationEnabled  = true
self.MyMapView.camera = camera

// Creates a marker in the center of the map.
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: pMyMapInf.MyDestinLatitude, longitude: pMyMapInf.MyDestinLongitute)
marker.title = pMyMapInf.MyDestinCity
marker.snippet = pMyMapInf.MyDestinCountry


print("Latitude is: \\(pMyMapInf.MyDestinLatitude) ")
print("Longitude is: \\(pMyMapInf.MyDestinLongitute) ")
print("City is: \\(pMyMapInf.MyDestinCity) ")
print("Country is: \\(pMyMapInf.MyDestinCountry) ")

marker.map = mapView

MyMapView.animate(to: camera)

}

And I have this Observer to trigger the above function.

var MyMapInfo:MyMapInf = MyMapInf()
{
didSet{
InitGoogleMaps(pMyMapInf: MyMapInfo)
}
}

so what happens is: on my FirstVC I create a new instance of MyMapInf()

var loFVcMyMapInf = MyMapInf()
SecondVC.MyMapInfo = loFVcMyMapInf

and I present the SecondVC(or I present the SecondVC then set didset observer , When this happens I see that my function is triggered and I see the values I print on the console, however, there ain't any movements on the map or a marker. it's still what am I missing here?
