The Swift code that's generated is pretty good, but I found myself pretty much immediately wanting to edit it.

I now maintain a separate copy of the templates that implemented some missing features of the spec that I needed, and adjusted access control etc to suit my needs. And I also feel like checking the generated code into source control is the way to go, if only for the build time improvements. I mean it doesn't change often enough to warrant being rebuilt all the time.
