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?
I have almost updated my app 10 times or more.
But I did not documented my app's build numbers. I have even deleted old archives from Xcode organiser. I checked App Store Connect's version history but it only shows App Versions and not Build Numbers.
Is there any way to know build version for all my app updates and releases?

After implementing SplitViewController for CollectionViewController... I noticed when I toggle switch for SplitViewController gap between two cells breaks or layouting of Cell i.e. sizeForItemAt
I have implemented multitasking - view for my app. i.e. if traitCollection.verticalSizeClass == .regular && traitCollection.horizontalSizeClass == .regular etc.

I want to disable Dark Mode system wide.
Apple Developer has mentioned that you can add 'UIUserInterfaceStyle' key to info.plist. But I checked there is no such key in list and it also gives error when you upload app to the App Store.
I tried using below code in AppDelegate.swift file.
window?.overrideUserInterfaceStyle = .light'
But it seems above code doesn't apply to LaunchScreen.storyboard
How to fix this?
That is LaunchScreen should also obey command to disable dark mode system wide.
I have implemented three tab bar view controllers for my app. Each tab has collection views, And I have implemented following code in my ViewController to change tab bar image icon from stroke to fill on respective tab bar selection. I am using System Icons (SF Symbols).
My Code:
self.tabBarController?.tabBar.items?[0] = UITabBarItem(title: "Myanmar", image: UIImage(systemName: "m.square.fill"), selectedImage: UIImage(systemName: "m.square"))
self.tabBarController?.tabBar.items?[1] = UITabBarItem(title: "Singapore", image: UIImage(systemName: "s.square"), selectedImage: UIImage(systemName: "s.square.fill"))
self.tabBarController?.tabBar.items?[2] = UITabBarItem(title: "Hyderabad", image: UIImage(systemName: "h.square"), selectedImage: UIImage(systemName: "h.square.fill"))
Error that I am getting at AppDelegate is: "Directly modifying a tab bar managed by a tab bar controller is not allowed."

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...
My Questions:
If I implement Trial period then can I offer free app as my previous user have already bought my app when it was paid.
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...
