TagView | Quick , convenient label on the view | Data Labeling library

The app has the following setup:

My main view creates a tag cloud using a SwiftUI ForEach loop. The ForEach gets its data from the @Published array of an ObservableObject called TagModel. Using a Timer, every three seconds the ObservableObject adds a new tag to the array. By adding a tag the ForEach gets triggered again and creates another TagView. Once more than three tags have been added to the array, the ObservableObject removes the first (oldest) tag from the array and the ForEach removes that particular TagView.

With the following problem:

The creation of the TagViews works perfect. It also animates the way it's supposed to with the animations and .onAppear modifiers of the TagView. However when the oldest tag is removed it does not animate its removal. The code in .onDisappear executes but the TagView is removed immediately.

I tried the following to solve the issue:

I tried to have the whole appearing and disappearing animations of TagView run inside the .onAppear by using animations that repeat and then autoreverse. It sort of works but this way there are two issues. First, if the animation is timed too short, once the animation finishes and the TagView is removed, will show up for a short moment without any modifiers applied, then it will be removed. Second, if I set the animation duration longer the TagView will be removed before the animation has finished. In order for this to work I'd need to time the removal and the duration of the animation very precisely, which would make the TagView very dependent on the Timer and this doesn't seem to be a good solution.

Another solution I tried was finding something similar to self.presentationMode.wrappedValue.dismiss() using the @Environment(\.presentationMode) variable and somehow have the TagView remove itself after the .onAppear animation has finished. But this only works if the view has been created in an navigation stack and I couldn't find any other way to have a view destroy itself. Also I assume that would again cause issue as soon as TagModel updates its array.

I read several other S.O. solution that pointed towards the enumeration of the data in the ForEach loop. But I'm creating each TagView as its own object, I'd assume this should not be the issue and I'm not sure how I'd have to implement this if this is part of the issue.

Here is the simplified code of my app that can be run in an iOS single view SwiftUI project.

I am fairly new to android & Java.

I am getting Index out of bound error for the first time.

I have looked at all the solution & tried debugging but I can't resolve it.

I'm getting this weird error when I try to upload images. The upload to the server works, but then immediately after I'm getting the error. When I only upload text it works fine, but when I try to use the imagesID after I upload, it gives this error. Does anybody know why I'm getting this error, and how to fix it?

I'm getting the error on line "this.state.imagesID.push({key:key });" in xhr.onreadystatechange which is inside the upload() function

My the class with the error:

I have an API call to list tasks from the database. Now I can able to retrieve tasks and loaded in the collection view. When tap creates a new task button, I will fill the form and save it to the database. When going back to the task list it will hit API and list old tasks with new tasks. But, In my, it shows duplicate tasks too.

For Example:- My task array [task1, task2, task3] but the result [task1, task2, task3, task 3, task 1]

Here is my code for the API call.

I'm trying to do something that's pretty straight forward in my mind.

I want a subview of a VStack to dynamically change its height based on its content (ProblematicView in the sample below).

It usually works pretty well, but in this case ProblematicView contains a GeometryReader (to simulate a HStack over several lines).

However, the GeometryReader greedily takes all the space it can (the expected behavior happens if you remove the GeometryReader and it's content). Unfortunately on the Parent view (UmbrellaView in the sample below), the UmbrellaView VStack assigns 50% of itself to the ProblematicView instead of the minimal size to display the content of the view.

I've spend a few hours playing with min/ideal/maxHeight frame arguments, to no avail.

Is what I'm trying to achieve doable?

I added pictures at the bottom to clarify visually.

I am trying to create a small reusable view for the "tags" at the bottom ("PC-12 Restricted" and "PC-24 Restricted").

This is the code I have, and mostly it's working.

I am developing an end-point where users can get the categories and only admin can create them. I am using Django and DjangoRestFramework. More specifically I am using ListCreateAPIView.

Here is my code.

I am using TaglistView to show tags in UITableViewCell. https://github.com/ElaWorkshop/TagListView

Now need to get id for the tag selected on a particular index path.

eg: JSON array is in format:

Index 0 : [{ name: "abc", value: "11" },{ name: "c", value: "12"}]

Index 1 : [{ name: "abcd", value: "21" },{ name: "abcde", value: "22" }]

Index 2 : [{ name: "abcde", value: "31" }, { name: "abcde", value: "32" }]

Code that I have used for adding taglist:

I have some problem ListView in ScrollView not displaying all items

and I try this code, it works but it takes a long time to process in the Adapter.

I have tried this code which is faster but doesn't display all items

How do I fix it?

Note: my ListView id is lv_poll_feed
