How to add custom subclass in cocoa framework

Question

I have just started making a custom library for reusing. I have multiple files which I want to put in that reusable file and am able to do that. But the problem is that I while importing all files are getting imported, I am want to import specific .swift file.

How can I implement that?

Example: I want to add multiple .swift in CocoaLibrary folder. and when import CoCoaLibrary, I want to do import like

import CocoaLibrary.CommonConstant

I don't know the path to implement this, so just mentioning the desired result.
