I liked the one he wrote ;). Last year (BC), I enjoyed Advanced Swift. In fact, I was inspired to write a collection utility, based on it.

He knows his stuff; especially when teamed with the wizards at objc.io.

But the classics are never out of date. Rapid Development, along with other McConnell classics, is a "must-read," as far as I'm concerned.
