this is a quote form apple news website : "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" , so i wouldn't consider this as a work around for solving this problem , any other ideas ?
