@a9wtPrLyjKTbNH0 you could play with this script but I'm almost sure that @mikael would give a better way with his anchor module

cgs = tvo.sizeThatFits_(CGSize(textview.width,2000))
textview.height = cgs.height

tv.border_width = 1 # only to show height automatically varying

tv.text = 'a\n'*20
sv.add_subview(tv)
