按id对自定义对象的SwiftUI数组进行排序

struct Person: Identifiable {
    let id: Int
    let name: String
}

let people = [
    Person(id: 3, name: "Charlie"),
    Person(id: 1, name: "Alice"),
    Person(id: 2, name: "Bob")
]

let sortedPeople = people.sorted { $0.id < $1.id }

import SwiftUI

struct ContentView: View {
    let sortedPeople: [Person]

    var body: some View {
        List(sortedPeople) { person in
            VStack(alignment: .leading) {
                Text(person.name)
                    .font(.headline)
                Text("ID: \(person.id)")
                    .font(.subheadline)
                    .foregroundColor(.gray)
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView(sortedPeople: [
            Person(id: 3, name: "Charlie"),
            Person(id: 1, name: "Alice"),
            Person(id: 2, name: "Bob")
        ].sorted { $0.id < $1.id })
    }
}
