  • Apple Announces 64-Bit Requirement for All iOS Apps Starting February 2015


    In a recent announcement made on its developer web portal, the Cupertino California company informed developers that apps must include 64-bit support and be built with the latest iOS 8 SDK starting February 1st of the next year. This wasn’t really a surprise considering most of the current iOS devices are powered by 64-bit A7 or A8 chips. Apple said the following on the Developer webpage regarding the matter:

    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.

    The Cupertino California company was the first to bring a 64-bit portable computing mainstream with the iPhone 5S in 2013 and has since expanded the processors to the iPad. With the introduction of this year’s iPhone 6 and 6 Plus, the only iOS device left without the 64-bit support is the company’s iPhone 5C which is now being offered as a free on-contract option from wireless carriers.

    For those of you who didn’t remember, the 64-bit chips in smartphones and tablets previously “set off panic” for chipmakers like Qualcomm which didn’t have roadmaps as aggressive as Apple’s rollout. Competitors ended up dismissing the technology stating it was unnecessary but ended up changing their route sinking R&D funds into building their own 64-bit products which ended up rolling out shortly after the A7 chip hit the market.

    Developers looking to update their apps with 64-bit support can download the latest version of Xcode with the up to date iOS 8 SDK through Apple’s Developer Center.

      Would this remove apps from the store without support or simply not allow new apps/updates not supporting it?

      My guess is that they will just not allow updates to apps that are not coded for 64bit. If they removed all the 32bit apps, all the people with phones prior to 5S would not be able to download any apps anymore. That would not fly at all with customers or the world at large. Look at how freaked out people got over getting a free music album!

      That's what I figured. Considering that some apps still aren't even updated for the iPhone 5 screen it may be a while before we get 100% 64bit compatible apps.

      With iOS 8, most devices are 64-bit anyway. I'm hoping with the launch of iOS 9 or 10 we will see the removal of 32-bit devices as well as non-retina devices. This causes such a pain for developers and even stops them from fully optimizing their apps for the majority of the devices using the App Store.

      Not exactly. People with old phone would still be able to download apps, as Apple is advising developers to include both 32 and 64 bits in same app.

      x64 is backwards compatible with x32. You're not going to lose support for the apps you already own if you have an iPhone 4.

      But new apps submitted to the store will soon be required to be x32 with mandatory x64 support, most likely.

      Not all apps need 64bit processing.

      I think you have it backwards. Most 64-bit operating systems can run 32-bit code, but in general 32-bit systems cannot run 64-bit code.
