Apple has announced that its new iOS 11, launched at its developer conference in San Jose, will only operate on 64-bit devices, making the iPhone 5 and 5C, among other devices, obsolete and meaning some apps and games may stop working.

The new version of iOS features a new interface and redesigned App Store, but also removes support for 32-bit devices and apps. Apple's iPhone and iPads have both used 64-bit processors, which allow the system to use larger amounts of memory among other speed advantages, since the A7 processor came with the iPhone 5S and iPad Air in 2013.
