> In retrospect I enjoyed this a lot, for two reasons. One is that getting code review from experienced engineers is one of the best ways to grow as a programmer, and the Apple engineers came from a totally foreign engineering culture — no unit tests! no comments! — that also was clearly producing a high-quality product.

Anyone know if this still applies to Apple’s SW engineering culture? Or if it’s just some urban myth? Hard to believe.

From my experience observing Apple and Google in WebKit and LLVM project: it's relative. Of course Apple's culture is not literally "no unit tests" and "no comments", as can be easily verified by looking at sources Apple released. On the other hand, I do think Apple's culture was "less unit tests" and "less comments" compared to Google, and it still is.
