Core Animation creator leaves Apple for Facebook

updated 04:24 pm EDT, Thu May 22, 2014

Also credited with number of other OS X, iOS technologies

John Harper -- the creator of the Core Animation framework used in iOS and OS X -- has left Apple for a position at Facebook, according to posts on Twitter. Core Animation first appeared in the iPhone OS in 2007, and migrated to OS X months later. Harper has spent over 12 years at Apple in total, and is credited with helping on a number of other iOS/OS X components as well, including Core Image, the port of X11, and OS X's windowing system.

Harper is due to join Facebook next week. His departure from Apple could potentially affect the direction of iOS and OS X, but no major redesigns are expected until 2015 at the earliest.
