Unless I am missing something, didSelectRowAtIndexPath: is never implemented in RootViewController. So, at the bottom of page 179 when the book states, "You should also be able to select tasks in the Tasks screen and view them in the ViewTaskController screen.," I don't see how that's possible. It is implemented in the downloaded solution code, but the book never implements it.

... the book is.

Did you also notice the incorrect error code for the priority edit controller?

OK. What needs to happen in the edit date controller
