Newline and / or carriage return in Swift String

I am trying to add Newline or Carriage return to UITextView.

    var text = UITextField()
    text.text = "This is a text \r\n This is a text"

      

        
        
        
      

    

The result shows all the text on one line:

This is the text This is the text

Can't draw new line or CR in UITextView? Or what am I missing here?
