title: how to always show TextView text above keyboard in swift?
body: <p>I have a Textview that's covered partially by the keyboard when it shows. As a result, the text which entered into the space covered by the keyboard can not be seen as it is typed. 
  How do I make the TextView scroll up when the entered text reached the space covered by the keyboard? </p>
  
  <p>I have scroll enabled on the TextView but since all the text is visible on the screen , the vertical scroll bar is not visible. Can I have the vertical scroll bar visible at all time event when editing?</p>
