Keyboard is not being dismissed: Facebook Account Kit iOS 11

Question

I have integrated Facebook Account Kit SDK v.4.26.0.

Following is the scenario in which I am facing difficulty:
When user clicks on sign in, Login with Phone Number controller is being presented and keyboard is appeared immediately on that screen to enter phone number. Now I tap on anywhere in the screen outside textfield & keyboard to trigger keyboard dismiss event. But from iOS 11.*, keyboard is not dismissed and if I navigate back by clicking back button, in that situation also keyboard remains open. Keyboard dismiss action works fine before iOS 11.0.

Following are the steps I have tried to resolve this problem:
1. Using AKFViewController instance which is presented for authentication, I tried to execute view.endEditing(true) in order to dismiss keyboard from delegate methods of AKFViewControllerDelegate . ( This method did not worked )

Answer 1

This is fixed in the 4.28.0 release
