Using debounce on a single-element publisher like dataTaskPublisher does not make sense. What sort of output do you expect with using debounce?

However it is working now and I am very grateful! Happy to hear that. Frankly I was at a loss how I should tell what is wrong... I will try better if I have another chance. Good luck.

Hardly to say anything with the fragments of code currently shown. Please include enough code (including class/struct headers and how those types are instantiated).

Create a function to execute all of them and call it.

Where is your ZStack embedded? Can you show all the code?

There may be some problems in your code. Can you create a minimized project which can reproduce the issue and show all the code? Just a short fragment of code would not help finding what is the problem.

Please show the class header of the view controller and the part defining leaderBoardTableView. Your code looks as if it is a subclass of UITableViewController.

The back button in the UINavigationBar under control of UINavigationView is constructed based on the settings of the previous view controller. Please try this:         self.navigationController?.navigationBar.backItem?.backButtonTitle = backButtonTitle (Not topItem, but backItem. Modifying topItem would be effective only before the navigation takes place.) By the way, your question is not related to the SwiftUI framework and the tag SwiftUI is not appropriate. Better use UIKit instead.

These are Class ! Stating it as class is not the definition.

I want to check if the element 'Medic()' exists in my array.  It depends on the definition of Medic and other types in the array.

What do you get with all the prints in your code?

AdMob is not a framework nor a service of Apple's. You should better find an appropriate channel to ask about it.

Thanks for showing the new code. But there is still no code using counter.

place the ContentView() in NavigationView{}, Why are you putting NavigationView in your RiyaVitaMealApp? You have two NavigationViews nested (one in RiyaVitaMealApp and one in ContentView), which causes two navigation bars stacked. It may look like too much space on the top. Please try removing one of the NavigationViews.

I made sure I was adding in SWIFTACTIVECOMPILATION_CONDITIONS As far as I tried in one of my project with Xcode 12.4, SWIFT_ACTIVE_COMPILATION_CONDITIONS is shown in Swift Compiler - Custom Flags section of Build Settings as Active Compilation Conditions. Not in User-Defined. Not sure if Xcode has moved it or you had done it wrong. But please try add one in Active Compilation Conditions.
