How to store a complex structure data in Core Data?

Forums > SwiftUI

Hello, I want to storage a structure wtih more than 10 variable. The sturcture is like this:

var option_1: [String]
var option_2: [String]
// ...
var option_n: [String]

struct Item {
    var name: String

    // The following  variable attr_i can choose one option from option_i: [String]
    var attr_1: String
    var attr_2: String
    // ...
    var attr_n: String

And I want to show them in a List line by line. Howerver, List can get most 10 subview, so I can't list them like:

List {

  // I alse want to make each attr_i could taggle from option_i: [String], 
  // for example by using Picker
  // ...

And create this many attribute in Core Data and use them one by one is imposible.I try to use ForEach to get the attribute of Item but I failed.

This problem makes me clueless and gets me nowhere

So I want to aks how could I get some structure that can storage in Core Data and CloudKit and alse I can show them in a easy way, and each attr_i could taggle from option_i: [String].

I would really appreciate it if you could help me or give me some hints.
