Content not refreshed when creating new views

[razyalov]

I have the QGrid setup to render a list of objects that are converted to views inside the QGrid’s block. When my API fetches updated data the view is rebuilt. I confirmed that the QGrid is called again, yet, it keeps rendering the initial list of views and not the newly created views. If I switch to List it works properly. Only with QGrid it doesn’t refresh. Here is the code in question:

    var body: some View { self.makeView()
        .onReceive(timer) { _ in
            self.refreshView()
        }
    }
    
    private func makeView() -> some View {
        VStack {
                Text("Dashboard").font(.largeTitle)
            if self.circuits.count > 0 {
                // need to use an if, b/c showing scrollable view without content will not refresh later on
                    QGrid<[CircuitInfo], CircuitCell>(self.circuits, columns: 2, columnsInLandscape: 4, vSpacing: 10, vPadding: 10, isScrollable: true) { circuit in
                        CircuitCell(circuit: circuit)
                }
            }
            Spacer()
            HStack {
                Text("\(self.circuitsCount())").font(.footnote).padding(5)
                Spacer()
                Text("Updated: \(lastUpdated)").font(.footnote).padding(5)
            }
        }
    }

Any ideas as to what I might be doing wrong?

I also have a data source being updated and the grid is not being refreshed

  @ObservedObject var viewModel: ViewModel

  var body: some View {

    QGrid(
      viewModel.attachments,
      columns: horizontalSizeClass == .compact ? 2 : 3,
      vSpacing: 24,
      hSpacing: 16,
      vPadding: 16,
      hPadding: 16
    ) {

      AttachmentButton(
        viewModel: AttachmentViewModel(attachment: $0)
      )

    }
    .onAppear(perform: viewModel.load)
    .navigationBarTitle("Attachments")

  }

Replacing QGrid with List works, but not the desired layout.

QGrid

Did you figure out a way out for this issue?

Ended up writing my own version from scratch.

Thanks for replying. Even I had to create my own solution. But mine is not generic. I have to create a grid for every type of data. Is it possible for you to share the approach you followed?

Very similar to the QGrid source code just without all the configuration options. I divide my list into rows and add them into a vstack of hstacks inside a parent scroll view.
