A terse but very clear message directed at registered developers has been sent out this week from Cupertino: all app submissions from February 1 forth must support 64-bit architectures and iOS 8. No ifs or buts.
Apple is making it clear, albeit using very mild vocabulary, that it will no longer accept non-iOS 8 submissions starting early next year. The reasons are obvious: to reduce fragmentation in the ecosystem.
The memo was posted on the News and Announcements area on Apple’s dev portal. It states that “Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later.”
