如何在SwiftUI中使用搜索栏过滤对象数组？

struct Person {
    let name: String
    let age: Int
}

@State private var searchText = ""
@State private var filteredPersons: [Person] = []

TextField("Search", text: $searchText)
    .textFieldStyle(RoundedBorderTextFieldStyle())
    .padding()

filteredPersons = persons.filter { person in
    return person.name.localizedCaseInsensitiveContains(searchText)
}

List(filteredPersons, id: \.self) { person in
    Text(person.name)
    Text("\(person.age)")
}

import SwiftUI

struct ContentView: View {
    struct Person {
        let name: String
        let age: Int
    }
    
    let persons = [
        Person(name: "John", age: 25),
        Person(name: "Jane", age: 30),
        Person(name: "Alice", age: 35)
    ]
    
    @State private var searchText = ""
    @State private var filteredPersons: [Person] = []
    
    var body: some View {
        VStack {
            TextField("Search", text: $searchText)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
            
            List(filteredPersons, id: \.self) { person in
                Text(person.name)
                Text("\(person.age)")
            }
        }
        .onAppear {
            filteredPersons = persons
        }
        .onChange(of: searchText) { newValue in
            filteredPersons = persons.filter { person in
                return person.name.localizedCaseInsensitiveContains(searchText)
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
