• Developers Can Reportedly Exclude 32-bit Device Compatibility in Apps Made for iOS 9



    As many of Apple's mobile devices are now using the 64-bit chip architecture, since the initial unveiling of the A7 chip with the iPhone 5s in 2013, Apple will give App Store application developers the ability to phase out support for 32-bit App Store applications that are made for iOS 9.

    As first noted by 9to5Mac Wednesday morning, this gives developers the power to reduce compatibility with devices such as the iPhone 4s, iPhone 5, iPhone 5c, and iPod touch 5g, as well as early versions of the iPad. This might be a necessary step for CPU intensive applications that just won't run well on the older mobile processors and performance suffers as a result.

    Developers are likely to be pleased with being given the power to choose to do the extra work to support 32-bit devices or simply support Apple's latest 64-bit devices. The majority of developers will likely still support 32-bit devices considering 32-bit devices make up a huge chunk of the iOS device market to this day. The additional flexibility, however, will certainly be nice for them.

    It is worth noting that Apple will not be phasing out any legacy iOS devices with the launch of iOS 9; all devices capable of iOS 8 can run iOS 9.

      It probably has to do with app slimming so that universal apps don't need 32 and 64 bit resources on a device that only needs one or the other.
