You should set up API keys before you set up the UIWindow in AppDelgate, if your initial View Controller uses GoogleMaps.

For example:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        //MARK: Google Maps setup
        GMSServices.provideAPIKey("YOUR API KEY")
        GMSPlacesClient.provideAPIKey("YOUR API KEY")

        let window = UIWindow(frame: UIScreen.main.bounds)
        window.backgroundColor = UIColor.white
        window.makeKeyAndVisible()
        window.rootViewController = ViewController()
        self.window = window
        return true
    }
