How to write a native application for macOS?

Question

macOS

I want to write a program for my poppy, where I can store my notes in a certain way and structure files. Could you suggest what tools to use.

I realized that I set myself xCode, use SwiftUi to build the interface and Swift as the base language. And no more frameworks and stuff is needed?

In the Apple documentation, I often see mention of UiKIt (as I understand it, this is a legacy component for drawing interfaces), Cocoa (As I understand it, this is the name of the macOS platform API, analogous to winAPI).

In the latest version , iOS apps run on Macs in two ways:
1) ARM-based Macs simply run the app. It can only be adapted to the iPad, it can be adapted to the poppy. Either way, it's an iPad app with nuances. You can write in SwiftUI and Swift + UIKit. What do you like.
2) Macs on Intel can run applications that are adapted through Catalyst . In a way, it's already outdated.
Both ways are not native development . You don't need it, use the migration tools.
UIKit is a framework with visual elements . Buttons, controllers, sliders from Apple.
