Hello I have a Core Data model with 18 attributes, name of Entity is Item, its attributes are attr_1, attr_2, ... , attr_18 and all of them is String type, however, the following code didn't work :

struct ContentView: View {
  @Environment(\.managedObjectContext) private var viewContext

  @FetchRequest(
        sortDescriptors: [NSSortDescriptor(keyPath: \Item.name, ascending: true)],
        animation: .default)
  private var items: FetchedResults<Item>

  var body: some View {
      List {
          Text(items.attr_1)
          Text(items.attr_2)
          // ...
          Text(items.attr_11)  // ERROR: Extra argument in call
          // ... 
          Text(items.attr_18)
      }
  }
}

So how could I make sure every attribute could show in the List? I would really appreciate it if you could help me or give me some hints.

Create a computed property on your Item entity which returns an array of your attributes. Then us a ForEach to create your List. With this approach you can show more than 10 Views.

Hi @Heyya-x! I am sure there is a better solution, but quick fix can be this version ->

List {
    ForEach(items) { item in
      Group {
        Text(item.att_1)
        ...
        Text(item.att_10)
      }
      Group {
        Text(item.att_11)
        ...
        Text(item.att_18)
      }
   }
}

Basically, you are grouping up to ten views in container...

if there is no need to loop through the items so you can just put views as static by grouping them:

List {
    Group {
      Text(item.att_1)
      ...
      Text(item.att_10)
    }
    Group {
      Text(item.att_11)
      ...
      Text(item.att_18)
    }
}
