Depending on the amount of text in the textView, the following can cause the textView to go completely blank or scroll to a location in the middle of the text and prevent the user from scrolling to the end of the text. let nsRange = NSMakeRange(textView.text!.count - 1, 1) textView.scrollRangeToVisible(nsRange) I'm looking for a workaround to do the simplest thing in the world: scroll the damn textView to the bottom.
