Swift Google Place Autocomplete not working wtih Google Maps - ios

Question

I am using a search bar to use Google Place Autocomplete feature. However, it is not working when I am putting the search bar on top of GMSMapView. It works completely fine when I comment out loadView() function. Is there a way to use the place autocomplete with Google map?
import UIKit
import GoogleMaps
class ViewController: UIViewController {
var resultsViewController: GMSAutocompleteResultsViewController?
var searchController: UISearchController?
var resultView: UITextView?
override func loadView() {
let camera = GMSCameraPosition.cameraWithLatitude(1.285, longitude: 103.848, zoom: 12)
let mapView = GMSMapView.mapWithFrame(.zero, camera: camera)
self.view = mapView
}
override func viewDidLoad() {
super.viewDidLoad()
resultsViewController = GMSAutocompleteResultsViewController()
resultsViewController?.delegate = self
searchController = UISearchController(searchResultsController: resultsViewController)
searchController?.searchResultsUpdater = resultsViewController
let subView = UIView(frame: CGRectMake(0, 65.0, 350.0, 45.0))
subView.addSubview((searchController?.searchBar)!)
self.view.addSubview(subView)
searchController?.searchBar.sizeToFit()
searchController?.hidesNavigationBarDuringPresentation = false
// When UISearchController presents the results view, present it in
// this view controller, not one further up the chain.
self.definesPresentationContext = true
}
}
// Handle the user's selection.
extension ViewController: GMSAutocompleteResultsViewControllerDelegate {
func resultsController(resultsController: GMSAutocompleteResultsViewController,
didAutocompleteWithPlace place: GMSPlace) {
searchController?.active = false
// Do something with the selected place.
print("Place name: ", place.name)
print("Place address: ", place.formattedAddress)
print("Place attributions: ", place.attributions)
}
func resultsController(resultsController: GMSAutocompleteResultsViewController,
didFailAutocompleteWithError error: NSError){
// TODO: handle the error.
print("Error: ", error.description)
}
// Turn the network activity indicator on and off again.
func didRequestAutocompletePredictionsForResultsController(resultsController: GMSAutocompleteResultsViewController) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictionsForResultsController(resultsController: GMSAutocompleteResultsViewController) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
}
The code above is from https://developers.google.com/maps/documentation/ios-sdk/map and https://developers.google.com/places/ios-api/autocomplete. I copied these for testing and is still not working.

Sorry, I don't have the reputation to write comments yet, but I think this could help you to figure out the issue.
First call the super.loadView() and when you initialize the GMSMapView you must set a frame size. Finally add the mapView to the subview.
override func loadView() {
super.loadView()
let camera = GMSCameraPosition.cameraWithLatitude(1.285, longitude: 103.848, zoom: 12)
let mapView = GMSMapView.mapWithFrame(self.view.frame, camera: camera)
self.view.addSubview(mapView)
}
