I have recently started using SwiftUI and have build up a simple app that fetches data from a web service. I have following code in my View

    struct ProductsView: View {
    @EnvironmentObject var viewModel: ProductViewModel
    
    var body: some View {
        NavigationView {
            List(content: {
                ForEach(viewModel.products, id: .self) { product in
                    ProductRow(product: product)
                }
            })
            .padding()
        }
        .task {
            try? await viewModel.fetchProducts()
        }
        .alert(isPresented: $viewModel.showError) {
            Alert(title: Text("Error"), message: Text($viewModel.productError.wrappedValue?.localizedDescription ?? ""), dismissButton: .default(Text("OK")))
        }
    }
}

The app works fine but When I run above code with debugger the viewModel.fetchProducts() is called three times which is surprising as I have only used it once. Can someone please suggest how can I improve it?
