No matching architecture in universal wrapper using Carthage

It compiles fine.
But when it runs it gives an error:
FBSnapshotTestCase.framework/Frameworks/libswiftCore.dylib: no matching architecture in universal wrapper)

FBSnapshotTestCase is actually a unit test, so this probably isn't supposed to work in a UITest target
