ios – Improper merchandise will get deleted from LazyVGrid

My purpose is to create a listing like this in SwiftUI

Each time the person faucets add, a brand new row is created after which on swiping to delete, the respective row must be deleted.

So as to try this, I begin with a really primary mannequin

struct SnagItem: Codable {
    personal(set) var reference: Int = 0
    personal(set) var particulars: String = ""
    personal(set) var isCompleted: Bool = false
    
    enum CodingKeys: String, CodingKey, CaseIterable {
        case reference = "Reference"
        case particulars = "Particulars"
        case isCompleted = "IsCompleted"
    }
}

extension SnagItem: Hashable { }

I exploit this mannequin inside a view mannequin which I want to bind to my SwiftUI view, that is the view mannequin:

class SnagItemViewModel: ObservableObject {
    personal let snagItem: SnagItem
    
    @Printed var particulars: String = ""
    @Printed var isCompleted: Bool = false
    
    init(withSnagItem snagItem: SnagItem) {
        self.snagItem = snagItem
        particulars = snagItem.particulars
        isCompleted = snagItem.isCompleted
    }
}

I’ve one other view mannequin that retains monitor of all of the snag gadgets (rows) utilizing an array. This additionally handles the including and deletion of things.

class SnagItemsViewModel: ObservableObject {
    @Printed var snagItems: [SnagItemViewModel] = [SnagItemViewModel(withSnagItem: SnagItem())]
    
    func getSnagItem(at index: Int) -> SnagItemViewModel {
        snagItems[index]
    }
    
    func addSnagItem() {
        snagItems.append(SnagItemViewModel(withSnagItem: SnagItem()))
    }
    
    func deleteSnagItemRecord(at indexSet: IndexSet) {
        guard let index = indexSet.first else { return }
        snagItems.take away(at: index)
    }
}

@Printed var snagItems: [SnagItemViewModel] = [SnagItemViewModel(withSnagItem: SnagItem())]

I’ve created a SwiftUI view that acts as a container:

struct SnagItemsView: View {
    @StateObject var snagItemsViewModel: SnagItemsViewModel
    
    var physique: some View {
        ForEach(0 ..< snagItemsViewModel.snagItems.rely, id: .self) { snagItemIndex in
            let snagItemViewModel = snagItemsViewModel.getSnagItem(at: snagItemIndex)
            
            SnagItemRowView(reference: snagItemIndex + 1,
                            snagItemViewModel: snagItemViewModel)
        }
        .onDelete(carry out: delete(at:))
    }
    
    func delete(at indexSet: IndexSet) {
        withAnimation {
            snagItemsViewModel.deleteSnagItemRecord(at: indexSet)
        }
    }
}

Every row then has it is personal view:

struct SnagItemRowView: View {
    @State var reference: Int
    @StateObject var snagItemViewModel: SnagItemViewModel
    
    let gridItemColumnConfig = [
        GridItem(.fixed(Constants.Frame.minGridItemWidth)),
        GridItem(.flexible()),
        GridItem(.fixed(Constants.Frame.minGridItemWidth))
    ]
    
    var physique: some View {
        LazyVGrid(columns: gridItemColumnConfig, spacing: 8) {
            ForEach(0 ..< SnagItem.CodingKeys.allCases.rely, id: .self) { columnIndex in
                
                let snagItemCategory = SnagItem.CodingKeys.allCases[columnIndex]
                
                if snagItemCategory == .reference {
                    Textual content("(reference)")
                } else if snagItemCategory == .particulars {
                    TextField(snagItemViewModel.localizedText(for: .enterValue),
                              textual content: $snagItemViewModel.particulars,
                              axis: .vertical)
                } else {
                    Toggle("", isOn: $snagItemViewModel.isCompleted)
                        .labelsHidden()
                }
            }
        }
    }
}

The whole lot appears to work high quality for essentially the most half.

It begins off like this:

When the person faucets Add, one other row is added and doing this a number of instances provides extra rows:

The problems start, when I attempt to delete:

As you’ll be able to see I am attempting to delete row 3, after deletion that is the result’s that row 4 will get deleted as an alternative, atleast from a UI perspective:

I printed out the values from my get operate and it appears that evidently the view mannequin truly appears to have the proper objects, the SwiftUI View does not appear to render the proper knowledge nevertheless for some purpose:

I added a breakpoint in my delete operate, to see if the precise index was being handed and it looks as if every thing appears good right here:

Lastly, when I attempt to add one other row after the deletion course of, the previous knowledge appears to be added again once more:

And once more, once I verify the view mannequin, the info appears to be proper, however the SwiftUI view exhibits one thing else.

What am I doing improper and the way may I repair this ?
