Problem

I'm trying to follow the Date Planner tutorial and the symbol picker went really weird.
I changed sth, and the whole app stoped working
I changed it back, it still wont work.
SymbolPicker code:

struct PickerView: View {
    @State var item: TodoItem
    @State private var showingPopover: Bool = false
    var columns = Array(repeating: GridItem(.flexible()), count: 6)
    var body: some View {
        LazyVGrid(columns: columns){
            ForEach(SymbolOptions.symbolNames, id: \.self){ symbol in
                Button {
                    item.symbol = symbol
                } label: {
                    Image(systemName: symbol).foregroundColor(item.color)
                }
            }
        }
    }
}
