How to build single binary with 32 bit & 64 bit in xcode 6

Question

I have followed this stack overflow solution but even though i am getting below warning.

Missing 64 bit support.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.

I have chosen

 Project - Target - Build settings - Architectures - Standard Architectures(armv7,arm64). 

eventhough i am getting above warning. please help me out.Thanks in advance.

Answer 1

Had the same issue. It looks like adding 'arm64' to the Valid Architectures (also under build settings) solved it.
