Apple Tells Developers It's 64-Bit Or Bust For iOS 8 Apps Starting In February
"To enable 64-bit in your project, we recommend using the default Xcode build setting of 'Standard architectures' to build a single binary with both 32-bit and 64-bit code," Apple says.
This shouldn't come as a bombshell to iOS developers. After all, just about every current iOS device is rocking a custom 64-bit A7 or A8 series System-on-Chip (SoC). That's been true since the iPhone 5c, and with Apple's recent product launches (iPhone 6, iPhone 6 Plus, iPad Air 2, and iPad mini 3), the iPhone 5c stands out as the only modern iOS device without 64-bit support.
What will this mean for you, the end user? That remains to be seen. Though there are performance benefits to be tapped into by moving to 64-bit, we've yet to see anything particularly meaningful on the mobile front. However, with Apple now forcing the issues, it could motivate developers to not only make the switch to 64-bit coding, but also to fine tune their new apps.
