Some suggested that in Apple’s next mobile operating system, Ive is pushing a more “flat design” that is starker and simpler, according to developers who have spoken to Apple employees but didn’t have further details. Overall, they expect any changes to be pretty conservative. For the past few years, Apple has unveiled versions of its mobile operating system in the summer.
This is all in-line with a couple of whispers I’ve heard. There will be some fairly significant changes to the design within some key apps and system-level elements, but overall, don’t expect a hugely different iOS.
