Exception:Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:...] prior to use

Question

I am trying to implement Google Maps SDK into my project using Swift 2.0. I follow this but when running this, my app is getting the following error:

2015-08-25 19:05:17.337 googleMap[1919:54102] *** Terminating app due to uncaught exception 'GMSServicesException', reason: 'Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:...] prior to use

I have tried all possible solutions from StackOverflow.

Answer 1

You need to set this both in didFinishLaunchingWithOptions

GMSPlacesClient.provideAPIKey("Your key")
GMSServices.provideAPIKey("Your key")

Answer 2

Just adding to Rajasekaran Gopal

Remember to add

import GoogleMaps
import GooglePlaces

then

GMSPlacesClient.provideAPIKey("Your key")
GMSServices.provideAPIKey("Your key")

in didFinishLaunchingWithOptions

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()
