Things i tried

I have restricted bundle id in api console .
I also tried removing StorageWithTileProto.omo file.
I cleaned project several times.
I restarted phone several times.
I also created new project ,that show same error .

This is my code

import Foundation

import UIKit

import GoogleMaps



class GoogleMaps :UIViewController {



 var gsmMapView: GMSMapView!







@IBOutlet weak var mapView: UIView!



let loacationManager = CLLocationManager()



override func viewDidLoad() {



    navigationController?.navigationBar.barTintColor =  

  UIColor.hexStringToUIColor(hex: "#555555")



    loacationManager.delegate = self



    loacationManager.requestAlwaysAuthorization()









    // Zoom to location

    let camera = GMSCameraPosition.camera(withLatitude: 0,

                                          longitude: 0, zoom: 6.0)

    // get google Maps

    gsmMapView = GMSMapView.map(withFrame: CGRect.zero, camera: 

    camera)

    mapView.addSubview(gsmMapView)



    }



   func toast(message msg: String) 

   {self.navigationController?.view.makeToast(message: msg)}

    }





extension GoogleMaps : CLLocationManagerDelegate{



func locationManager(_ manager: CLLocationManager, 

didChangeAuthorization status: CLAuthorizationStatus) {



    print("status (status.rawValue)")

    if(status != CLAuthorizationStatus.authorizedAlways){



        permissionDialog()

        return

    }

    loacationManager.startUpdatingLocation()











}



func locationManager(_ manager: CLLocationManager, didUpdateLocations 

 locations: [CLLocation]) {



    toast(message: "didUpdateLocations")

    guard let location = locations.first else {

        return

    }



    // 7

    //        gsmMapView.camera = GMSCameraPosition(target: 

           location.coordinate,

       //       zoom: 15, bearing: 0, viewingAngle: 0)

    //        

    // 8

    loacationManager.stopUpdatingLocation()

}



func locationManager(_ manager: CLLocationManager, 

  monitoringDidFailFor region: CLRegion?, withError error: Error) {

    print("Monitoring failed for region with identifier:  . 

     (region!.identifier)")

 }



func locationManager(_ manager: CLLocationManager, didFailWithError 

 error: Error) {

    print("Location Manager failed with the following error:  . 

 (error)")

}





func permissionDialog() {

    self.toast(message: "Give Always Authorization Premission")



    let alertController = UIAlertController(title: "Permission",

                                            message: "Please go to 

  Settings and turn on the location alway               permissions 

    for to work",

                                            preferredStyle: .alert)

    let settingsAction = UIAlertAction (title: "Settings", style: 

    .default, handler: ({ (_) -> Void in



        guard let settingsUrl = URL(string: 

 UIApplication.openSettingsURLString) else {

            return}

        if(UIApplication.shared.canOpenURL(settingsUrl)){

            UIApplication.shared.open(settingsUrl, options: [:], completionHandler: { (success) in })



        }

    }))

    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, 

  handler: nil)



    alertController.addAction(settingsAction)

    alertController.addAction(cancelAction)

    self.present(alertController, animated: true, completion: nil)

}

}
