Apple has announced that developers must ensure that all app submissions are optimized for iOS 7 by February 1, 2014, according to a new posting on its developer portal.

This includes both new apps and updates to existing ones. In order to optimize apps for the new OS, they must be built with the latest version of Xcode 5 — which includes 64-bit support, and access to features such as backgrounding APIs.
