iOS 11 may require 64-bit apps


Since February 2015, Apple has required submitted apps to be 64-bit compliant. iOS 11 could potentially be the inevitable cut off for old apps that have not since been updated.

Apple Insider:

With the first iOS 10.3 beta, Apple inserted a message warning that 32-bit apps "will not work with future versions of iOS." Previously iOS only cautioned that 32-bit apps might slow down a device.

It's speculated this could affect as many as 187,000 apps in the App Store. That number though could be reduced if Apple continues culling the App Store of outdated apps. Either way, if an app hasn't be updated by time iOS 11 launches (2.5 years), odds are it's abandoned by the developer and it's time to move on.
