Mark Gurman is back at it again over at 9to5Mac. He has some of the best sources and a very impressive track record for Apple rumours and scoop over the past couple of years.
Here's what he has to say this time:
Sources tell us that iOS 9 engineers are putting a “huge” focus on fixing bugs, maintaining stability, and boosting performance for the new operating system, rather than solely focusing on delivering major new feature additions. Apple will also continue to make efforts to keep the size of the OS and updates manageable, especially for the many millions of iOS device owners with 16GB devices.
If true, I think this is a great direction for Apple. In iOS 8, almost my entire wish list of new feature requests was addressed. Now, if they would all work much more reliably, I would be a very happy camper. I expect that the media will try to spin this negatively, as they generally do with Apple news, but I think Apple can sell it just fine. All the really hard core iOS users are begging for these bug fixes, and all "normal" users—99.9% of the user base—barely use most of the new or power user features anyway. I know of all my friends, I have to teach most of them about the new features I think they would find useful. Not one of them could explain an extension, or continuity, or customizable share sheets.
