AttributedStringWrapper is a simple packaging for NSAttributedString to make the developers easy to use
AttributedStringWrapper is base on String extension, converted into RawRepresentable protocal in order to solve the question of Objective-C namespace. So it looks a bit strange, if you have a better way, please contact me
