I wonder when this picture was taken. The iPhone design in the simulator, the old Gmail favicon, the old OS X scrollbars all indicate this being several years old.
Wouldn't be surprised if this code has been rewritten multiple times since.

Between iOS and macOS, and given the acquisition was in 2012, I'd imagine these photos were taken around then.
This code also appears not to be using automatically synthesized properties. On the left screen, they're directly accessing Ivars and their Ivars have trailing underscores rather than leading (the default when synthesized). I suppose they could be doing this anyways, though it wouldn't exactly be standard industry practice.
On the right Xcode screen, though, the code does use property syntax, so potentially ARC, although one doesn't imply the other.
