why have the BNRCoursesViewController class extension in BNRAppDelegate.m as described on page 10860 in the Kindle edition?
I left the extension in BNRCoursesViewController.m (where I see more use for it) and the code works as I expected.
And, I was not able to find the place in the book, where the code should be added there (BNRAppDelegate.m).
Please let me know where I’m missing something.
Thanks and cheers,
