Apple have reminded developers that starting on February 1st, new apps submitted to the App Store must include 64-bit support and be built using the iOS 8 SDK. Starting on June 1st, the same requirements are necessary for updates submitted for existing apps.
Apple has told developers that by using the default X code build setting “Standard architectures,” they can build a single binary with both 32-bit and 64-bit code.
The new rules though, won’t affect any iPhone model older than the Apple iPhone 5s.
As we announced in October, beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures†to build a single binary with both 32-bit and 64-bit code.
