Hi I am using showcase for displaying help text for user first time login.But I am facing few issues in iOS 12 version.
I am presenting a showcase and meanwhile if get a notification I will navigate to another screen.After dismissing from Second Viewcontroller If I tap on screen showcaseview next sequeence is showing.

I am not sure how to kill the showcase view instance completely.
