Apple introduced its first 64-bit, the A7 chip, back in 2013 with the iPhone 5S. The company also released its first OS version built on 64-bit architecture in that year as well. However, starting with iOS 11, which is set to launch later this year, the Cupertino-based giant will drop the support for all the 32-bit apps on the App Store. In other words, if you are used to running a lot of apps or games built on 32-bit architecture on any of the previous iOS versions, you will not be able to do so on the next iOS version i.e. iOS 11.
Some of the apps running on the recently released iOS 10.3 have already started showing warnings which read – “ This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility”.
The old apps and games can only be saved if the developer updates to compatibility or develop the app on the 64-bit architecture. However, if a developer fails to do so, be ready to bid adieu to your favourite games post next update. If you are not aware, Apple has already made mandatory for all the new apps to come with 64-bit compatibility. Further, Apple gave a deadline until June 2015 to all the developers to make all the apps and games 64-bit compatibility post which the developer was forced to update the compatibility. If failed, such apps will not be supported on iOS 11.
To sum up, new iPhones which will be updated to iOS 11 will not support older games or the games which are not updated to 64-bit compatibility. Although there has been no official statement from Apple about anything of this sort, but, the company has already been contacting various developers to update their apps to 64-bit. In future, Apple might also eventually force users to shift to new hardware i.e. a new or upcoming iPhone and iPad.
Nevertheless, if you are running on an older iPhone which is not built on 64-bit SoC (Processor), it is not long when app developers entirely drop the support for 32-bit devices.
