Shortly after iOS release 8.1 for iPhone, iPad and iPod Touch, the Apple company has published in the information center dedicated to application developers for the iOS platform an information that will surely displease a good part of the users. As of February 1, 2015, any application submitted for publication or update in the App Store must be developed using iOS 8 SDK and must have support for 64-bit processors implemented.
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 rule requires that some applications must be compatible only with iOS 8, or iOS 7 in the rarest cases, so the update to the latest version of the operating system will be mandatory at the beginning of next year. Apple was mocked for the low number of users who updated to iOS 8 this fall, and now it has found a fix for the problem, so you should prepare to update in the coming months.
