iCloud storage tools might not ship
[Updated with alleged icons] If the ports are finished in time, iOS 8 may include versions of OS X's Preview and TextEdit apps, according to claims by questionable sources say. Unlike their Mac counterparts, the iOS apps reportedly won't be able to actually edit images, PDFs, or text documents. They are, however expected to support viewing OS X documents stored in iCloud; for management and editing, people will be directed toward existing apps like iBooks and Pages, says the rumor.
The new apps are believed to be possible through corporate restructuring done by Apple's head of Software Engineering, Craig Federighi. Teams are no longer constrained by platform, and so can be asked to develop apps and features for iOS and OS X simultaneously. Under Apple's earlier organization, an iOS team might have simply attempted to duplicate Preview and TextEdit in their own way.
The company is also said to be investigating new iCloud storage tools that could make it easier to develop server-integrated iOS apps. Developers have often complained that iCloud integration can be unwieldy; it's unclear though if the tools will actually launch, since Apple engineers have proposed them unsuccessfully in the past.
Update: An alleged early iOS 8 screenshot shows icons for Preview and TextEdit, as well as Healthbook, a rumored forthcoming health- and fitness-related app. The authenticity of the rumors and images haven't been verified.
