ActivityIndicatorView | A number of preset loading indicators created with SwiftUI | Frontend Framework library

I have created this custom code to create a loader in my project. The problem is that I have to copy and paste this function in all my classes. Is there any way I can declare this code in one global functions class and just use them wherever I want to use by calling.

I used NVActivityIndicatorView to create a loading page and turn over the tab screen for 5 seconds.

ActivityIndicatorView is short-lived and disappears quickly. Using a timer, I made an event happen in five seconds. Timer.scheduledTimer()used DispatchQueue.main.async{}. I thought it runs main thread. I changed timeInterval, and it didn't change.

I have a basic view that displays a list that fetches data from an API. I want to implement an activity indicator while the data is being retrieved from the API. In MVC we could use a delegate and protocol and make the view controller inherit the protocol, and after the model has finished fetching the data we call the delegate to tell the view controller that the data has finished retrieving (now hide the activity indicator, etc.). How to achieve a similar thing in SwiftUI and it's MVVM style?

I have tried implementing an activity indicator from this question, I just don't get how and when to stop it: Activity indicator in SwiftUI

My SourcesViewModel (it fetches news article sources from newsapi.org)

NEHotspotConfiguration works well, but the error is nil both when the SSID I am trying to connect to is not available (out of range or off) or when the password I've submitted is incorrect.

What am I doing wrong? I want to be able to distinguish between these two scenarios so I can inform the user accordingly.

Code snippet:

This problem has been answered several times before on this site, I have tried them all and none work. The difference I think is that I have a UITableView inside my UIViewController. I have tried when loading the data within viewDidLoad, here the screen I am coming from show until all is complete and my new view appears. I have also tried within viewDidAppear, here I have a blank table showing before the final view comes up.

I have tried 4 methods all from this site, I call pauseApp(n) before I start the load and restartApp(n) when completed

I have a video player and a UIView overlaying it which I use for Gesture Recognition in the video area. I am doing this so you can tap different area of the video to play, rewind and do other functions.

At the moment, this works fine in landscape but if I rotate the device to portrait. The UIView doesn't resize but the video player does. I tried to use constraints programmatically but I can't figure out how to access the NSLayout anchor of the video player.

I have a function which retrieve the size of the video frame which I currently use to set the UIView to the size of the video player.

The code below can be just copied into a project to play a video and show the UIView I want to adjust. You just need to add UIView to the UIViewController storyboard. The code does not contain the GestureRecogniser part.

I am parsing a feed of json data representing events. On a day where there ARE events, the json feed will be a Dictionary of Dictionaries, and looks something like this:

I'm trying to add a child view controller to a parent view controller in a swift ios application, but when I add the child view controller, the activityIndicatorView doesn't appear. What could I be missing? Here is a snippet that can be tried in a playground:

I want to run UIActivityIndicator when the application is opened. How can I do this? My code is the way I share it down there. I want this code to work when Launchscreen opens.
