Not sure if this belongs in Aurelius or DBSchema, but it would be nice to be able to read a swagger spec and generate an interface unit (optional) and implementation unit for Delphi from it with stub methods that can be filled out.
An interactive tool would be nice so if it's a huge spec and you only need a few things, then you can select the ones you want and it will pull in all of the dependent classes and definitions needed so it compiles without error and without all of the additional stuff you don't need. (This should probably be part of Delphi, but they don't think it's important.)
