Facebook login, when i'm press continue from facebook interface, it crashing on my iOS11.3 version. it quitely working good in ios11.4 and iOS11.03 lowers versions.

回答1:

It got resolved by the Facebook developer team. Meanwhile, we have to use the following snippet for iOS11.3. If older Methods also will work i think.

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
}
