Converting ViewController Module to External Swift Package

I used the Local Folder UIKit-Based ViewController Module to select three Xcode projects that may work differently with string values stored in each Xcode Project Helper File.

However, I have Successfully converted that Module to an Independent Swift Package And was able to deploy it on GitHub for easy use with different projects without having to update each file everywhere.

But Now the string value that the Package depended on is not taking that value from the Xcode project it has been added to.

So, How do we get value from the Xcode project for an independently added Swift Package to make it work?
