With iOS 8, Apple opened the floodgates of third-party keyboards, custom sharing and action options, contextual Spotlight, Extensibility that allows for interactive notifications, Family Sharing options and Continuity workflows, and many more. It also brought on updates to Messages and Photos, like custom photo filters and effects, improved Mail and Safari, and a fresh Health app, among many other things.
It now seems that Apple is hard at work already testing iOS 9, according to Google Analytics, as you can see below. Tim Cook said Apple will try and release a new major version of iOS and Mac OS each year, and, given the Analytics screenshot here, it is intent to deliver.
Unfortunately, at this point in time, it is anyone's guess what the update is going to include, but if last year is any indication, we can expect Apple's "walled garden" gate to be left ajar a tiny bit more - who knows, maybe even homescreen widgets will be in store. We kid, but iOS 9 should be revealed for the masses during WWDC at the beginning of the summer, and there is plenty of time for the leaks to trickle through and form a veritable river of information about what lies ahead for iOS. In the meantime, check out this iOS 9 concept video below, which condenses a wish list of the new features folks would like to see with this year's Apple mobile OS update.
