screen not zoom to right coordinates - swift google map api - swift

Question

when getting dynamic google map with using GMSMap the map doesn't show the current location that i gave him and not zoom the map
import UIKit
import GoogleMaps
import MapKit
class LocationItemViewController: UIViewController,GMSMapViewDelegate, CLLocationManagerDelegate {
#IBOutlet weak var lblInfo: UILabel!
#IBOutlet weak var lblTitle: UILabel!
#IBOutlet weak var viewMap: UIView!
#IBOutlet weak var googleMapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
let latitude = (String(format:"%.02f", locationItem.itemLatitude ) as NSString).doubleValue
let longgitude = (String(format:"%.02f", locationItem.itemLongitude) as NSString).doubleValue
let camera = GMSCameraPosition.cameraWithLatitude(latitude,longitude: longgitude, zoom: 7)
let mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView.myLocationEnabled = true
self.googleMapView = mapView
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake((locationItem.itemLatitude as NSString).doubleValue, (locationItem.itemLongitude as NSString).doubleValue)
marker.title = "somelocation"
marker.snippet = "anywhere"
marker.map = mapView
lblTitle.text = locationItem.itemName
lblInfo.text = locationItem.itemAddress
}
I was locate the GMSServices.provideAPIKey("YOUR_API_KEY") in app delegate

To display your current location you have to do the same thing which we do for apple maps to access our location.
In plist you have to add 2 entries and take permission from User
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
Check this link for more details iOS 8 CLLocationManagerDelegate methods are never called
Now regarding your google maps zoom issue
var mapView:GMSMapView?
Now in your viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
GMSServices.provideAPIKey("YOUR_API_KEY")
//Taking HardCoded lat longs for the time being. These lat longs are of New Delhi, India
let camera = GMSCameraPosition.cameraWithLatitude(28.6139, longitude: 77.2090, zoom: 10)
mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView!.myLocationEnabled = true
self.view = mapView
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(28.6139, 77.2090)
marker.title = "Delhi"
marker.snippet = "India"
marker.map = mapView
//As view takes some time to load so I am calling my zoom function after a delay of 1 second. You can use the zoom function code in viewDidAppear too
//Also this syntax is the latest Swift 2.2 syntax. If you are using the old Swift version, make the changes accordingly for performSelector method
self.performSelector(#selector(zoom), withObject: nil, afterDelay: 1.0)
}
Here is the zoom method
func zoom() {
CATransaction.begin()
CATransaction.setValue(1, forKey: kCATransactionAnimationDuration)
// It will animate your camera to the specified lat and long
let camera = GMSCameraPosition.cameraWithLatitude(28.6139, longitude: 77.2090, zoom: 15)
mapView!.animateToCameraPosition(camera)
CATransaction.commit()
}
