App Rejected Due to Missing NSPhotoLibraryUsageDescription

I had an app using this library get rejected for a missing NSPhotoLibraryUsageDescription when submitting with Xcode 8. I think it's due to the use of UIImagePickerController in XLFormImageCell.

My app doesn't use this cell or access the user's photo library in any way, so I'd prefer to not have to set a fake usage description. Is there any way to conditionally not compile this class, or create a CocoaPod subspec that doesn't include the XLFormImageCell?

Thanks
