VersionNumber and VersionString in umbrella header

I am adding a new framework to a Swift + Objective-C project. So, into my framework, I have an umbrella header: xFramework.h

#import <UIKit/UIKit.h>

//! Project version number for xFramework.
FOUNDATION_EXPORT double xFrameworkVersionNumber;

//! Project version string for xFramework.
FOUNDATION_EXPORT const unsigned char xFrameworkVersionString[];

I don't want to depend upon UIKit in my framework. But, if I remove the import, FOUNDATION_EXPORT will not be found.

1. How much from this autogenerated file do I really need?
2. Are the xFrameworkVersionNumber and xFrameworkVersionString[] needed to be used in a Swift Framework?

I've understood from this question that FOUNDATION_EXPORT is a kind of public.

Thank you.
