Apps running on 32-bit code needs to switch.
Apple has announced that starting from 1st February next year all the newly submitted apps and updates of the existing apps must have 64-bit support.
The company will not accept the apps that do not have 64-bit support in the App store; instead it has recommended app developers to switch from 32-bit code to 64-bit code.
For developers creating new apps will mean using the latest iOS 8 SDK, included in Xcode 6 or later, and reports suggest that the process of app development will become easier.
The move is also expected to encourage developers to tune the apps for Apple’s A7 and A8 chips.
The transition is likely to have positive impact on the Apple devices’ performance as they will not have to juggle between 32- and 64-bit codes.
Apple said in its blog: "Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be 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."
