If you're recompiling with iOS SDK 9.0, add the following to your application's plist if you're using a version of the Facebook SDK v4.6.0 or above:

   LSApplicationQueriesSchemes
   
          fbapi
          fb-messenger-api
          fbauth2
          fbshareextension
   

To prepare the facebook integration supported to iOS 9, go through Facebook Integraion for iOS 9 guidelines

To check version of facebook SDK, use below line of code:

   print("SDK version \(FBSDKSettings .sdkVersion())")
