tapp | tap { pp self } | iOS library

I'm thinking how to conditionally permit to start NavigationLink when user has tapped it. In UIKit it is just obvious but in SwiftUI this seems to me a huge problem. I know that I could declare NavigationLink somewhere in my view i.e.

I was making the responsive mobile version of a website, when I discovered that the body expands when resizing the window, here's a screenshot of it (the header is pink so I could spot where the error was in pixels, ah yes, it's in Italian but don't worry):

This is the code:

What I'm trying to accomplish is when user selects an element for UITableView this element gets append to servicioSeleccionadoarray. But I'm stuck in this because if user decides to deselect the cell I want to remove that item from the array. I've try anyarray.remove(at:)but I can figure the way to tapp into that index. This is my code so far.

When I tap on the Edit button it functions correctly to change the list to an active state with a delete icon beside each item. However, the sort icon does not show on the right side of each item as expected.

This leads me to believe that I have overlooked a key element in the following code. What else is required to enable the sort option?

This is driving me crazy:

Team, this is driving me crazy. I always receive this error when I start the UWP application:

As EFCore in UWP is not able to dbscaffold the database, following the suggestions found here I did an EF.Core WPF application, scaffolded the database creating the classes... Imported the generated classes in the UWP application (renamed the namespace where applicable).

In the UWP application I've added the Microsoft.EntityFrameworkCore and Microsoft.EntityFrameworkCore.SQLServer and added the Enterprise Capability: Enterprise Authentication

So everything should be fine... but.. it does not work. Exactly the same LINQ query that works fine in the WPF gives me the error in the UWP

Any idea? what am I missing?

--- Edit 1

I've even added the code from this page:

Use a SQL Server database in a UWP app connectionString = "Data Source=YourServerName\SQLEXPRESS;Initial Catalog=NORTHWIND;Integrated Security=SSPI";

so to my case:

I want to display a popup or modal that says something along the lines of 'please be patient while processing' while the application is performing a function in the background. However the popup appears after the background function has already happened. Below is an example of code that produces this problem.
