Drag the generated files into Xcode and add them to your target.

Access localized singular strings:
Strings.Singular.uploader_errorAlert_message.localizedString => "The upload failed."

Access localized singular strings:
LocalizedSingularString(SingularString_uploader_errorAlert_message) => "The upload failed."
Access localized plural strings:
