Just upgraded to Xcode 5.1, getting the following error:
ignoring file ...Dependencies/SalesforceNetworkSDK/libSalesforceNetworkSDK.a, missing required architecture arm64 in file ...Dependencies/SalesforceNetworkSDK/libSalesforceNetworkSDK.a (3 slices)
If I turn off build active archs only and remove arm64 from valid archs I get:
See Question&Answers more detail:osBuild/Products/Debug-iphoneos/libPods.a, file was built for archive which is not the architecture being linked (armv7)
