I have few questions about implementing free trials for my UIKit Swift App. Currently my app is paid i.e. One time purchase. I have good amount of user who have purchased my app as an Paid app previously. Now I want to introduce Trial period for my app I am also exploring RevenueCat framework for this...

And new user can use my app for free for 14 days then one time payment will start. Is there any good documentation for this kind of logic / programming? with source code examples... Thanks in advance...

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?
