Issue with focus on ChattoViewController Start

[vpadmnabh]

Hi, I am preloading my data in Another ViewController and on display of ChattoViewController my array is already ready. When i open chats from starting are visible in the viewcontroller and i have to scroll down each time at bottom manually. I call self.delegate?.chatDataSourceDidUpdate(self, updateType: .normal) at the end of preload. If I try to change focus in ViewDidAppear the scroll to bottom is visible keeping animation flag to false also.
