iOS 7's release introduced a new visual interface for the operating system, and Apple updated most of its own apps to take advantage. Two notable standouts were iBooks. That was remedied today when Apple posted iBooks 3.2 and iTunes U 1.4 to the App Store.
With the initial release of iOS 7, iBooks retained a "skeuomorphic" look, displaying books in a wooden bookcase motif. But with iBooks 3.2, that real world simulation is gone. What's left is a clean, minimalistic look that better reflects the iOS 7 aesthetic.
iTunes U gives you access to complete courses from leading universities. Like iBooks, the iTunes U app wasn't updated with iOS 7's new look and feel when the new operating system bowed in September. But concurrently with the launch of iBooks 3.2, Apple has posted iTunes U 1.4, which also brings the interface in line with the iOS 7 aesthetic.
Apple notes no other changes for either version besides the interface update.
Apple is systematically getting rid of all traces of skeuomorphism in iOS 7, to match the new iOS 7 design. I doubt it'll ever go away completely, even in Apple's apps: a practical example is GarageBand, which uses dials, switches and instrument controls that mirror their real-world counterparts in form and function. But iBooks and iTunes U are two places where skeuomorphism just simply isn't necessary, so it's good to see them improve consistency with the rest of the OS.
Are you a heavy iBooks user? Do you download courses through iTunes U? Are you happy with the interface changes, or were you content with the bookshelf interface? Sound off in the comments - I want to know.
