I've achieved the functionality of changing text on a UILabel and applying styling to particular characters in a subset of a string used for that attributed text, for example on a string $0.00, I can change the alpha of only the ending '00' when the user has only typed '0.'
However, I'd like to then animate the letters as the come in. CashApp (reference) does something a bit similar to this... how can I smoothly animate only the text which is added to the label and not the entire label itself??
