如何使用JSON对SwiftUI中的列表进行排序

[
  {
    "name": "Item 1",
    "value": 10
  },
  {
    "name": "Item 2",
    "value": 5
  },
  {
    "name": "Item 3",
    "value": 8
  }
]

@State private var items: [Item] = []

struct Item: Codable, Identifiable {
    let id = UUID()
    let name: String
    let value: Int
}

.onAppear {
    guard let url = Bundle.main.url(forResource: "data", withExtension: "json") else { return }
    do {
        let data = try Data(contentsOf: url)
        let decoder = JSONDecoder()
        items = try decoder.decode([Item].self, from: data)
    } catch {
        print("Error decoding JSON: \(error)")
    }
}

func sortList(by keyPath: KeyPath<Item, Comparable>) {
    items.sort { $0[keyPath: keyPath] < $1[keyPath: keyPath] }
}

Button("Sort by Name") {
    sortList(by: \.name)
}
Button("Sort by Value") {
    sortList(by: \.value)
}
List(items) { item in
    Text(item.name)
    Text("\(item.value)")
}
