No template needed IMO.

I used CC just yesterday to build a native MacOS menu bar app by using plan mode (opus) until there was alignment then to edit mode for the build (I use Zed for the prompting).

CC walked me through the needed Xcode project setup and handled all of the code there after.

I’m sure something more complex would be more challenging but I was happy with a two-shot result for this native menu bar app.
