I have received email from app store.
"Missing 64-bit support "
We have discovered one or more issues with your recent delivery for "xxxxxxx". Your delivery was successful, but you may wish to correct the following issues in your next delivery:
Missing 64-bit support - Beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. 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.
After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.
