UITextView Scrolling Indicator issue

Question

My UITextView becomes scrollable at a certain number of lines. When I scroll up a paragraph of text, the scrolling indicator is not scrolling to the top of the UITextView but to the top of text container. Any suggestions?

Here's my UITextView code:

lazy var chatTextField: UITextView = {

    let chatText = UITextView()
    chatText.scrollIndicatorInsets.top = 0

    chatText.contentInset = UIEdgeInsetsMake(-40, 0, 0, 0)
    chatText.delegate = self
    chatText.backgroundColor = UIColor.clearColor()
    chatText.font = UIFont(name: "Arial", size: 16)
    chatText.textColor = UIColor(r: 120, g: 128, b: 125)
    chatText.translatesAutoresizingMaskIntoConstraints = false
    return chatText
}()

Take note of the scrolling indicator; it should be pushing the top part.

I use a collectionView and these lines of code work for me. Try:

dispatch_async(dispatch_get_main_queue(), {self.collectionView!.reloadData()
                    let indexPath = NSIndexPath(forItem: self.messages.count-1, inSection: 0)
                        self.collectionView?.scrollToItemAtIndexPath(indexPath, atScrollPosition: .Bottom, animated: true)
                    })
