Apple requires all new apps and version updates to support iOS 8 SDK and 64-bit

October 20, 2014, Apple official released a news, the news content is as follows:

Starting February 1, new iOS apps uploaded to the App Store must include 64-bit support and being built with the iOS 8 SDK, included in Xcode 6 or later. 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.

Requires that all new apps and newer versions of apps that have been submitted must use the iOS 8 SDK and provide 64-bit support since February 2015.

Apple's request for developers to use the iOS 8 SDK and last year's request for developers to use the iOS 7 SDK is similar, but the requirement to support 64-bit is substantial.

Apple unveiled its 64-bit A7 processor when it launched its iphone 5s in 2013. At present, Apple sells only a small number of low-end devices that do not support 64-bit, so this is a great opportunity for developers to support new technologies.

Support for 64-bit iOS apps must be built using the iOS 8 SDK, and 64-bit support means the app can take full advantage of the performance of Apple A7, A8, and A8X chips.
