  • Developers Alerted That They May Now Submit 64-bit Applications to the App Store


    On Monday, Apple notified developers that they could begin submitting applications to the App Store that will offer support for the 64-bit A7 chip, which will be included inside of every iPhone 5s.

    The notice is shown below:

    You can submit 64-bit apps for iOS 7 today that take advantage of the power of iPhone 5s. Xcode can build your app with both 32-bit and 64-bit binaries included so it works across all devices running iOS 7. If you wish to continue to support iOS 6 then you will need to build for 32-bit only. Next month we will be making changes that will allow you create a single app binary that supports 32-bit on iOS 6, as well as 32-bit and 64-bit on iOS 7.
    Notably, Apple appears to have removed the notice a while after putting it up, as MacRumors reports. It may have been an early notice. We assume that it would still be okay for developers to begin submitting 64-bit applications when they're ready.

    All applications built for iOS 6 will have to be 32-bit, as the iPhone 5s is not capable of running iOS 6. Developers that are making applications for iOS 7 will have the choice of creating 32-bit or 64-bit versions of their applications. It is also possible for developers to offer a 32-bit version of an application for iOS 6 and a 64-bit version of an application for iOS 7. Xcode will make it simple for developers to compile 32-bit and/or 64-bit versions of their applications as necessary.

    The iPhone 5s isn't the only device that's expected to have a 64-bit chip. The next generation iPad is predicted to offer a 64-bit A7X chip that will also be capable of running these specially-built applications.

      And is this supposed to be an amazing thing for us end-users? What is the benefit of having apps in 64bit? (Not being ironic, but I really don't understand the difference...)

      Thinking about the future, I'm sure phones won't be bottlenecked at 1GB of RAM forever.
