I wonder how to add complex labels to a button. I know that you can do it in the default label in the Attributes Inspector but I wish to do it programmatically also. By a complex label I mean newspaces, tabspaces, newlines, et cetera; along with the text of the label. I presume this is stored somewhere by the Attributes Inspector but I don't know where to find it. In any case, I wish to store in a string text that would be on several lines, with tabspaces and newspaces. Can strings store information in that manner in Swift 3? thanks for your time and patience postscript: is there any free program for mac that shows all carriage return, newlines, tablines, etc?
