I just had the same problem. I created a GMSMapView object and it was initialized before maybe the api key could be read. So I moved it inside the viewDidLoad method and problem solved.

Before :

class ViewController: ..... {

let mapView = GMSMapView()

After :

class ViewController: ..... {

var mapView : GMSMapView?

override viewDidLoad(){
    mapView = GMSMapView()
