Google Places Picker SDK (Not Working) Swift 4 - swift

Question

I recently decided to build an application using the Maps SDK from Google, but the problem is, when I open the view controller, it only let me click for the first item.
I cant find the solution using only the google documentation.
Anyone has a fix for this?
import UIKit
import GoogleMaps
import GooglePlaces
import GooglePlacePicker
class PlacePickerVC: UIViewController, CLLocationManagerDelegate, GMSMapViewDelegate, GMSAutocompleteViewControllerDelegate, UITextFieldDelegate {
let currentLocationMarker = GMSMarker()
var locationManager = CLLocationManager()
var local = ""
var morada = ""
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Teste"
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
locationManager.startMonitoringSignificantLocationChanges()
let config = GMSPlacePickerConfig(viewport: nil)
let placePicker = GMSPlacePickerViewController(config: config)
placePicker.delegate = self
present(placePicker, animated: true, completion: nil)
}
// Handle the user's selection.
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
//Display the places but only show
print("Place name: \(place.name)")
print("Place address: \(place.formattedAddress)")
print("Place attributions: \(place.attributions)")
dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
print("Error: ", error.localizedDescription)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
dismiss(animated: true, completion: nil)
}
}
extension PlacePickerVC : GMSPlacePickerViewControllerDelegate {
func placePicker(_ viewController: GMSPlacePickerViewController, didPick place: GMSPlace) {
print("Place name \(place.name)")
}
func placePicker(_ viewController: GMSPlacePickerViewController,
didFailWithError error: Error) {
// In your own app you should handle this better, but for the demo we are just going to log
// a message.
NSLog("An error occurred while picking a place: \(error)")
}
func placePickerDidCancel(_ viewController: GMSPlacePickerViewController) {
// Dismiss the place picker, as it cannot dismiss itself.
//viewController.dismiss(animated: true, completion: nil)
print("No place selected")
}
}
Numbers 1 2 and 3 can't be clicked.
