Answer 1

in my case --didFinishLaunchingWithOptions-- method didn't call because i updated swift version. first make sure this method called normally. and in my case i didn't need to GMSPlacesClient.provideAPIKey("Your key"). however you can initial GMSServices in your initial viewcontroller (if its not contain map or related objet to it)

Answer 2

You need to set this both in didFinishLaunchingWithOptions

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

Answer 3

In my app i provided key to GMSPlacesClient in AppDelegate -didFinishLaunchingWithOptions

Ex:
@import GooglePlaces;
@import GoogleMaps; 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [GMSServices provideAPIKey:@"You key"];
    [GMSPlacesClient provideAPIKey:@"Your key"];
}

For Swift:

import GoogleMaps
import GooglePlaces

//in application(_:didFinishLaunchingWithOptions:)

GMSServices.provideAPIKey("YOUR_API_KEY")
GMSPlacesClient.provideAPIKey("YOUR_API_KEY")

Answer 4

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
    }
