Xcode 5.1: missing required architecture arm64

According to apple’s release note, see the following note point.

Note:

Be aware of the following architectures issues when opening your
existing projects in Xcode 5.1:

  • When building for all architectures, remove any explicit
    architectures setting and use the default Standard Architectures
    setting. For projects that were previously opted-in using “Standard
    Architectures Including 64-Bit”, switch back to the “Standard
    architectures” setting.
  • When opening an existing project for the first time, Xcode 5.1 may
    display a warning about the use of the Xcode 5.0 architectures
    setting. Selecting the warning provides a workflow to revise the
    setting.
  • Projects not able to support 64-bit need to specifically set the
    architectures build setting to not include 64-bit.

So you’ve to set architecture as below to support libs architecture.

Update: From May 15, you’ve to take build from 5.1.1, see this post.
