解析json数据后更新swiftui文本视图

import SwiftUI
import Foundation

struct MyData: Codable {
    let name: String
    let age: Int
    // 其他属性...
}

let jsonString = """
{
    "name": "John",
    "age": 25
}
"""

if let jsonData = jsonString.data(using: .utf8) {
    do {
        let myData = try JSONDecoder().decode(MyData.self, from: jsonData)
        // 解析成功，可以在这里更新文本视图
    } catch {
        print("JSON解析失败：\(error)")
    }
}

struct ContentView: View {
    @State private var myData: MyData?
    
    var body: some View {
        VStack {
            Text("Name: \(myData?.name ?? "")")
            Text("Age: \(myData?.age ?? 0)")
        }
    }
}

if let jsonData = jsonString.data(using: .utf8) {
    do {
        let myData = try JSONDecoder().decode(MyData.self, from: jsonData)
        self.myData = myData
    } catch {
        print("JSON解析失败：\(error)")
    }
}
