Apple has posted a notice on their developer website reminding app developers that starting Feb. 1, all new iOS 8 software submitted to the App Store must include 64-bit support.
Today’s reminder is the second such notice sent out to developers ahead of Apple’s planned migration to a comprehensive 64-bit App Store. The company first announced 64-bit requirements for iOS 8 in October.
The 64-bit requirement is for new submissions only. Developers who want to update existing apps have until June 1, 2015 to build in 64-bit support. All newly submitted apps after Feb. 1 will need to be built using Apple’s iOS 8 software development kit.
The iOS 8 SDK is available via Apple’s Developer Portal, and is included as part of Xcode 6.1.1.
The iPhone 5s debuted in 2013 as the first mainstream 64-bit device, sporting the A7 SoC. Other device makers soon scurried to pledge 64-bit support for their future devices soon after the A7 was released.
