In this code, when I type GIDSignIn.sharedInstance, for some reason sharedInstance is not a function, which means I can't acces clientID. I cannot find a solution for this anywhere.
import UIKit
import GoogleSignIn
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
GIDSignIn.sharedInstance().clientID = "clientID"
return true
}
