Apple requires all developers to switch to 64-bit code support

From February next year, any application or update to get permission to publish in the App Store will have to support 64-bit code and be built on the iOS 8 SDK.

Apple informed iOS developers about this yesterday. 

The need to collect applications using the new SDK is not new, this could have been expected, given that last year the Apple company implemented the iOS 7 SDK in the same way. The only disappointing thing is that now developers will not be able to choose whether to work on 32-bit or 64-bit. 

It is clear that no one is going to delete applications that already exist in the App Store that do not support “progressive code”, but if the developers want to fix a couple of bugs, they will have to work hard on adapting the old project.
