Apple on Wednesday alerted members of its development community that existing applications on the App Store will need to include 64-bit support for any updates submitted after June 1 of next year. The clarification from Apple comes after developers expressed confusion regarding the company’s 64-bit app update policies. With Wednesday’s announcement, developers now have more than six months to prepare for the switch. All newly submitted apps will require 64-bit support beginning on Feb. 1, 2015. They must also be built with the iOS 8 software development kit as of that deadline.
Apple today began sending out emails to developers, reminding them that as of February 1, 2015, all apps submitted to the App Store need to be built with the iOS 8 software development kit and include 64-bit support. Developers were first informed of the upcoming rules back in October, after the release of iOS 8 and the iPhone 6/6 Plus. The email also states that as of June 1, 2015, all app updates submitted to the App Store will need to adhere to the same requirements, giving the company a way to make sure all current apps take advantage of 64-bit support and are iOS 8 compliant. The shift to across-the-board 64-bit support will offer improved app performance on 64-bit devices. “As we announced in October, 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. 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.”
