How to create a single binary with 32-bit and 64-bit in xcode 6

Question

I followed this decision, but even though I am getting a warning below.

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 chose

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

although I get a warning. please help me. Thanks in advance.

Answer 1

There was the same problem. It seems that adding “arm64” to the Valid architecture (also in the build settings) solved it.
