OS X 10.11 and iOS 9 (Mid 2015 Reveal, Late 2015 Launch)
As with the iPhone and the iPad, Apple releases new versions of iOS and OS X on a yearly basis. We don’t know much about OS X 10.11 or iOS 9 at this early date, aside from the fact that the two operating systems are in development.
With iOS 8, Apple intended to introduce features like improved transit and indoor mapping features for the Maps app and split-screen multitasking for the iPad. If these options don’t make it into an upcoming iOS 8 update, they could potentially be bundled into iOS 9. iOS 8 featured few visual changes, so iOS 9 could introduce both new features and some design updates to further refine the look unveiled with iOS 7.
