From the creator

There are many tasks during my development day that take up significant time, not because they’re complicated, but because they’re tedious. With Developer Duck, these tasks are significantly faster. I use it for adding DocC comments, writing simple extensions, writing tests for those extensions, and even researching unfamiliar APIs.
