Xcode 5.1: missing required architecture arm64

Question

Just upgraded to Xcode 5.1, getting the following error:

ignoring file ...Dependencies/SalesforceNetworkSDK/libSalesforceNetworkSDK.a, missing req

Answer 1

I ended up getting my project to build by (1) turning off build active archs only (2) removing arm64 from valid archs and (3) making sure that the Pods project was building for only armv7 and armv7s.

Also worth noting here, that at the time of writing this edit, Salesforce mobile SDK was not available for arm64

Answer 2

Don't know previous iOS but Setting Build Active Architecture Only to YES in iOS 8 did the trick.

Answer 3

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.

Reference from this post.

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

Answer 4

I just changed the Debug from Yes to No,

Build Settings -> Architectures -> Build Active Architecture Only -> Debug -> NO.

This one fixed my error.
