如何在swift中将JSON数据写入/保存到Xcode中的.json文件？

import Foundation

let user: [String: Any] = [
    "name": "John Doe",
    "age": 30,
    "email": "johndoe@example.com"
]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: user, options: .prettyPrinted)
    // jsonData现在包含了转换后的JSON数据
} catch {
    print("JSON转换失败：\(error)")
}

let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.appendingPathComponent("example.json")

do {
    try jsonData.write(to: fileURL)
    print("JSON数据已成功写入文件")
} catch {
    print("写入文件失败：\(error)")
}
