I am trying to show three things on map : GPS (the current location) , Marker 1 , Marker 2, but I am not sure I am doing it right or not ! Here is my code :
self.startMarker.position = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude) self.startMarker.icon = #imageLiteral(resourceName: "Pin Start") self.startMarker.map = self.mapView self.endMarker.position = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude) self.endMarker.icon = #imageLiteral(resourceName: "Pin End") self.endMarker.map = self.mapView let southWest = CLLocationCoordinate2DMake(self.startLatitude,self.startLongitude) let northEast = CLLocationCoordinate2DMake(self.endLatitude,self.endLongitude) let bounds = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest) let camera = self.mapView.camera(for: bounds, insets:.zero) self.mapView.camera = camera! More Code :
// MARK: - Google Map private func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) { if status == CLAuthorizationStatus.authorizedWhenInUse { mapView.isMyLocationEnabled = true } } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { let newLocation = locations.last mapView.camera = GMSCameraPosition.camera(withTarget: newLocation!.coordinate, zoom: 14) mapView.isMyLocationEnabled = true } The result is like this :
What I need :
EDITED
if let myLocation = self.mapView.myLocation { let path = GMSMutablePath() path.add(myLocation.coordinate) path.add(self.startMarker.position) path.add(self.endMarker.position) let bounds = GMSCoordinateBounds(path: path) self.mapView.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 40)) }

Showing All Markers with screen bound:
Here I am trying to provide you one simple example, hope this will help you. Using this, you can show any number of markers on screen.
Example:
let path = GMSMutablePath() for var i in 0 ..< array.count { let lat = Double(array.objectAtIndex(i).valueForKey(lattitude) as! String) let long = Double(arrayr.objectAtIndex(i).valueForKey(longitude) as! String) marker.position = CLLocationCoordinate2DMake(lat!,long!) path.addCoordinate(marker.position) marker.map = self.mapView } let bounds = GMSCoordinateBounds(path: path) self.mapView!.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 30.0)) Answers 2
Can you try the below code, this is converted from ObjC code here is the documentation of includingCoordinate
let bounds = GMSCoordinateBounds() bounds.includingCoordinate(self.startMarker.position) bounds.includingCoordinate(self.endMarker.position) bounds.includingCoordinate(yourCurrentLocationPosition) self.mapView.animateWithCameraUpdate(GMSCameraUpdate(fitBounds:bounds, padding:20.0f)) Answers 3
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { showMarkers(locations) //stop updating location when you find suitable } func showMarkers(userLocation: [CLLocation]){ let location1: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude) let location2: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude) let location3: CLLocationCoordinate2D = userLocation[0].coordinate var locationArray = [] locationArray.append(location1) locationArray.append(location2) locationArray.append(location3) var bounds = GMSCoordinateBounds() for location in locationArray { let latitude = location.valueForKey("latitude") let longitude = location.valueForKey("longitude") let marker = GMSMarker() marker.position = CLLocationCoordinate2D(latitude: latitude, longitude: longitude) marker.map = self.mapView bounds = bounds.includingCoordinate(marker.position) } let update = GMSCameraUpdate.fitBounds(bounds, withPadding: 100) mapView.animateWithCameraUpdate(update) } Note:
locationArray contains three locations ie. Marker 1, Marker 2, user location.
