Apple once again reminds developers of upcoming 64-bit bit app rules

Apple has issued an email to registered iOS app developers on Tuesday reminding them all iOS apps will need to include 64-bit support for the latest A-series chips. Apple has sent outprevious emails before, but it serves as another reminder before the change goes into effect.

“As a reminder, beginning February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK,” Apple’s email reads. Apps submitted without 64-bit support after the first of the month will not receive App Store approval, and the developer will be forced to make changes to support Apple’s latest A7 processor that features a 64-bit architecture.

Past new apps, developers will need to include 64-bit support in any future app updates starting June 1. If 64-bit support isn’t included, the update will not be accepted. Existing apps on the App Store that have already been approved by Apple will not be removed for not supporting 64-bit.

Apple brought 64-bit support to the iPhone 5s in 2013, and of course extended it to the iPad, iPhone 6, and iPhone 6 Plus. The iPhone 5c is the only current device in Apple’s lineup to not see the performance benefit of a 64-bit chip architecture that brings better performance to apps.
