Try the following code:

There are several ways to generate XML from tables in Oracle.

The main benefit to using the SQL functions (like XMLELEMENT and XMLFOREST) is that you don't have to iterate over a cursor line-by-line - you can do all the work in one query. Conversely, if you want to do it row-by-row with a cursor like that, using DBMS_XMLGEN would probably make more sense. You might want to do that if you have a lot of changes to make to the data before writing it to XML.

Here's a procedure to do it with XML SQL functions.

Apparently your problem is the architecture of your code. On loadPlaces you are iterating through your categories and doing several network calls. Then you append those results to places and use reloadData to reload the table, but on cellForRowAt you call loadPlaces again.

Even that you set isLoading = true inside loadPlaces you have multiple requests going on and all of them set isLoading = false at the end. So at some point you will have some unexpected result. You also have some force load cases that add up to all that.

Last but not least, since you are calling self.tableView?.reloadData() inside a closure, it its possible that its not updating correctly.

TL;DR

1. Wrap your reloadData around a DispatchQueue.main.async block.

2. Implement a queue that serialises your network requests to put some order around your calls. You can use a library like this for example.

It seems that the problem is clear - doneTap calls performSegue with sender set to nil:

I would suggest that you limit the number of cells inside UITableView delegate method number of cells

In the VC with the stepper, override prepareForSegue:

Let's recap.

Here you can find great answer on multiple selection: UITableView Multiple Selection

It starts with: tableView.allowsMultipleSelection = true

and so on.

now that i have tapped multiple lines how can i use this self.performSegue(withIdentifier: nearbySearchSegueIdentifier, sender: list[indexPath.row]) in a button func,

You don't have to provide sender with performSegue, it can well accept nil. Just specify segue id and nil as a sender and you're all set:

Look at what you are doing here:

You have to use begin & end update methods before and after your changes.
