How to call a function inside another?

How to call a function which has already been initialised, again ? I have a search bar which searches for particular word and if it finds it, it changes a particular value.

var mover: String!
@IBOutlet weak var searchBar: UISearchBar!

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
   let camera = GMSCameraPosition.camera(withLatitude: latPass, longitude: longPass, zoom: 5)
   let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
   view = mapView

}

I want my camera to change value according to my searchBar.text

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
    print(searchBar.text!)

    if searchBar.text!=="test"{
        mover="test"

    }
}

The value of mover is changed, but how to refresh the camera view so it animates to particular coordinates.

I think is bad approach instaciating your mapView every time your CLLocationManager give some valid position, taking in account your current implementation, you must add a flag variable to execute the code inside your didUpdateLocations only once

Code

var mover: String!
var positionWasUpdated : Bool = false
@IBOutlet weak var searchBar: UISearchBar!

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
   guard !positionWasUpdated else{
        return
   }

   let camera = GMSCameraPosition.camera(withLatitude: latPass, longitude: longPass, zoom: 5)
   let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
   view = mapView

}

After that when searchBar text is "test" you can use .animate(to:) method to animate the map to your new desired location

Code

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
    print(searchBar.text!)

    if searchBar.text!=="test"{
        mover="test"
        if let mapView = self.view as? GMSMapView
        {
            mapView.animate(to: GMSCameraPosition.camera(withLatitude: yourDesiredLatitude,
                                                      longitude: yourDesiredLongitude, zoom: 15.0))
        }
    }
}
