Apple Says New iOS Apps Must Include 64-bit Support by Feb. 1, 2015


Apple has announced to developers new iOS apps submitted to the App Store must support 64-bit apps starting on February 1, 2015:

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.

iOS apps with 64-bit support must be build using the iOS 8 SDK. The move looks to transition apps towards taking full advantage of Apple’s A7, A8 and A8X chips, which support 64-bit.

Oh, as for the developers out there, don’t forget you’ll still need to support the A5 processor found within the original iPad mini–a chip which debuted with the iPad 2 then made its way to the iPhone 4S back in 2011–for at least a couple more years.

    correction: A5 Debuted before iPhone 4S, with now discontinued iPad 2, so its even older 😛

  • Clarified thanks!

    What good is 64 bit with 1gb of ram in your phone! (roll eyes)
    Apps are going to get larger in size, less efficient, more power hungry. Some of the most reliable apps I have are 2 years old now and I keep them because they don’t use as much energy and don’t crash. THEY JUST WORK.

    What’s good having a 64bit processor without 64bit apps? They are obviously trying to transition everyone over, so when the 4/8GB devices come out there will be plenty of apps to take advantage.

    I don’t doubt it will work, I think it will be good for iPad because it has 2gb ram now, which will make things smoother. Apple has been on 1GB of ram for at least 3 years now with the iPhone, now would have been the right time to at least go to 2GB with the push for 64 bit. I think it will take a tidal wave of user feedback for them to finally make the update. I guarantee, the next iPhone release will have 2gb of ram. It will have to, because performance will suffer with 64 bit apps if they don’t.
