Using binary Swift SDKs from non-Swift apps

As an SDK developer, I'd like to convert my SDKs to Swift and still support non-Swift based apps. However, it seems that Xcode requires binary Swift SDK clients to add a dummy Swift file to their apps to avoid undefined Swift system library linkage failures. See examples here, here and here

Is there a way to get Xcode to implicitly link the Swift system libraries? Or anything in the Xcode roadmap to improve this use case?
