The built-in apps in Apple’s newly announced iOS 7 use Neue Helvetica almost entirely. This is not a change from previous versions of the OS (other than a system-wide switch to lighter weights), but the typeface is all the more front-and-center in iOS 7 now that the depth, chrome, and button outlines have faded away.
There are a couple of exceptions from this Helvetication, however. One is the Newsstand app icon, and another is in the UI for the new Camera app. While the rest of the system uses Helvetica for buttons and navigation, settings in the Camera app are conspicuously exempt from the overarching style. At the moment, the type appears to be a slightly modified DIN 1451 Mittelschrift, the mechanical typeface created as a standard for German signage and industry — though they may have based the controls on one of the other (more typographically optimized) variants of DIN.
I assume the goal here was to simulate the typical routed lettering on a classic metal-bodied camera, such as a Leica. The allusion is subtle and effective, but this is a curious departure from Apple’s new stand against skeuomorphism. Perhaps there are certain brands (like Braun and Leica) that are simply too loved by Ive and company not to be emulated.
