Apple announced yesterday:
Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. 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.
This means any projects in process need to switch to iOS 8 and 64-bit if they are going to launch after Feb 1. More importantly, all updates to old apps after that date will not be accepted unless the apps are updated.
To Do: Check immediately what iOS and what bit support (64 or 32) all you current public apps include, and begin making update plans for any legacy applications to ensure you don’t end up with an update you cannot submit.
As always, please do not hesitate to contact us if we can be of assistance.
