filemanager | OpenIntents file manager

So I am writing a test python program with PySimpleGui, and it looks like this:

I've just started working on my first project for macOS and am having trouble setting up a NSTableView. When I run it the window will appear but there is nothing in it. I've made sure all the objects have the correct class in the identity inspector and can't seem to find what I'm doing wrong.

The goal of the app is to make a notes app. I want a tableView which displays the titles of all the notes in the database, in a single column, so when you click on the cell the note will then be displayed in the rest of the window.

Here's the code:

How to achieve to listing all files (e.g. Media) inside hidden subdirectory i.e. folder name start with '.' e.g. "(.media)" after using SAF in Flutter/Dart?

I have used ACTION_OPEN_DOCUMENT_TREE to let the user choose a folder [So to avoid using MANAGE_EXTERNAL_STORAGE] but couldn't view i.e. Read the files inside the hidden subdirectory of the folder.

Permission Granted folder is media:

storage/emulated/0/internal storage/Android/media/matrix/.new/

Issue:

Not able to list all files inside subfolder .new

At the same time...

Able to access files (not folder) inside matrix subfolder

Also if I rename the subfolder ".new" to new I am able to list all the files inside that folder

This import worked up until now.

When using Xcode 13.2.1 and SwiftUI to implement a simple slideshow, I am hitting a compile-time error in which Xcode takes about 5 minutes on my M1 to decide it cannot parse my code, and eventually gives me the error:

The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

I narrowed it down to the NavigationLink line near the bottom. If I comment that out, it compiles quickly with only a warning.

The following is my Minimal, Reproducible Example:

I am loading images into a SwiftUI List. When too many images are scrolled down, RAM skyrockets and crashes app. Why are images not deallocated as user scrolls down past them?

I am loading images as so:

I am trying to perform a series of network requests and would like to limit the number of concurrent tasks in the new Swift Concurrency system. With operation queues we would use maxConcurrentOperationCount. In Combine, flatMap(maxPublishers:_:). What is the equivalent in the new Swift Concurrency system?

E.g., it is not terribly relevant, but consider:

unable to save the zip file to external storage after picking a folder using ACTION_OPEN_DOCUMENT_TREE.

I'm creating a project which creates and manipulate files and document, in that task I want to save that stuff in external storage but I can't do that with android developer documentation, so please explain additionally.

I want to save this file

I have this static class:
