TWTRComposerViewController not appearing in iPhone X landscape

问题

We are implementing TWTRComposerViewController in our landscape App for posting tweets from the App using videos created within the App. We're using the below written code:

    if (Twitter.sharedInstance().sessionStore.hasLoggedInUsers()) {

        let txtString = "App-Name"
        let composer = TWTRComposerViewController(initialText:txtString, image:nil, videoURL:nil)
        composer.delegate = self
        viewController.present(composer, animated: false, completion: {
            completion(true)
        })

    } else {

        Twitter.sharedInstance().logIn { session, error in
            if(error != nil){
                print(error?.localizedDescription)
                Error(error! as NSError)
            }
            if session != nil {
                let txtString = "Voki"
                let composer = TWTRComposerViewController(initialText: txtString, image: nil, videoURL:nil)
                composer.delegate = self
                viewController.present(composer, animated: false, completion: {
                    completion(true)
                })

            }
            else {
                completion(false)
            }
        }
    }

This works fine in all phones, iPhone 6, 6S, 7, 7 plus but in iPhone X, the composer doesn't appear. If we check presentedViewController then it shows that TWTRComposerViewController is presented but nothing appears on App and the screen freezes out.
