For iOS 11 / Swift 4 you should add the following code to your AppDelegate:didFinishLaunchingWithOptions

SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

Final code is:

import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.\

        // FACEBOOK CONFIGURATION
        SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)


        return true
    }
