Apple’s releases of each major version of iOS have all concentrated on WWDC, which makes a lot of sense since this is the World Wide Developers Conference that happens every year in June. As is obvious, iOS 7 was planned to be released on those dates, but that’s actually only two months away if you think of it.
Sources very close to Apple have begun the rumor that Apple is running behind on the development of the OS. Apparently the company is even using resources from OS X in their future 10.9 update (which sometimes varies in its release between WWDC and the fall) in order to reach the WWDC deadline of iOS 7. This is not new; as Apple had to do the same thing the first time they released the iPhone in 2007.
Sadly for Apple, iOS 7 is a different animal. There’s no more Scott Forstall, Apple is forced to change this operating system dramatically since we’ve been bored of it for almost three years now, and to make matters worse, iOS 6 has been a tremendous failure. We know this is Jony Ive’s first try at influencing the OS, and we’ll admit most of us can’t wait to see what’s under their sleeve. Hopefully they’ll be done on time, since there’s only a good amount of bugs a human being can take from iOS 7.
