How to define a UIView from a swiftUI View - swiftui

I need to adapt some sdk demo code from swift to swiftui .
In this code, an element must be created based on a UIView container defined in the storyboard
Setup idea: self.arViewContainer.frame
arViewContainer is non other than the main area of the phone in the storyboard .
I would like to know what to do in swiftui in order to have this setup based on my mainView

You need to make UIViewRepresentable struct, write in the typealias what UIView you need to adapt to, and then implement 2 methods which take in the typealias you provided (and then you can delete the typealias because you don't need it anymore, it's only for Xcode to understand what goes into the 2 methods):

What is the SwiftUI sheet view equivalent in UIKit?

SwiftUI can easily present a sheet view on top of the existing review when a condition is met (see screen record below). What is the sheet component equivalent in UIKit?
Tried to Google a result and it looks like there is a sheet related view called UIActionSheet, but that does not seem like the right UI control.
REFERENCE
Example of how to achieve the same behavior with UIKit.
iOS 14 navigation bar title is not displayed in UINavigationController created programmatically
This is just another UIViewController presented modally with a Done UIBarButtonItem on the right side.

Xcode 12 iOS 14 Widget without SwiftUI

Is it possible to create Xcode widget in Xcode 12 but without the use of SwiftUI and instead use XIB files to construct the Widget UI?
Widget protocol is only available in SwiftUI framework, so you can only create widgets using SwiftUI.

Update
You can't use UIKit views wrapped in UIViewRepresentable within SwiftUI for Widgets, It will appear blank.

No, due to performance and battery life concerns, WidgetKit only works with SwiftUI.
https://developer.apple.com/documentation/widgetkit
You configure the widget with a timeline provider, and use SwiftUI views to display the widget’s content. The timeline provider tells WidgetKit when to update your widget’s content.

installsStandardGestureForInteractiveMovement on UICollectionView in ViewController

I want to implement reordering of collection view cells in a collection view inside a View Controller, but the moveItemAt method is not being called since I can't seem to access the installsStandardGestureForInteractiveMovement property of the CollectionViewController.
I want to know if this property is exclusive to UICollectionViewController or I can somehow access it in UIViewController currently hosting it?

Presenting several times the same ViewController in a TabBar inside a storyboard

Hullo,
I would like to use the same view controller to present various information from within a tabbarcontroller. The number of view controllers will be established programmatically. I found a way to do it by initiating the other viewControllers with their nib, but by using StoryBoarding I have no cue about how to get the nib identifier of a viewController.
Is it possible to use this technique, or Segues give an alternative?
Thanks, Fabrizio
