You can use RxCoreLocation:

import UIKit
import GoogleMaps
import RxCoreLocation
import RxSwift

class MapViewController: UIViewController {
    private var mapView: GMSMapView?
    private let disposeBag = DisposeBag()
    private let manager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        manager.requestWhenInUseAuthorization()
        manager.startUpdatingLocation()

        let camera = GMSCameraPosition.camera(withLatitude: 0, longitude: 0, zoom: 17.0)
        mapView = GMSMapView.map(withFrame: .zero, camera: camera)
        view = mapView

        manager.rx
            .didUpdateLocations
            .subscribe(onNext: { [weak self] in
                guard let location = $0.locations.last else { return }
                let camera = GMSCameraPosition.camera(withLatitude: location.coordinate.latitude, longitude: location.coordinate.longitude, zoom: 17.0)
                self?.mapView?.animate(to: camera)
                self?.manager.stopUpdatingLocation()
            })
            .disposed(by: disposeBag)
    }
}
