如何在ios中找到json key名称或数据

struct MyDataModel: Codable {
    let key1: String
    let key2: Int
}

// 解析JSON数据
let jsonString = """
{
    "key1": "value1",
    "key2": 123
}
"""
let jsonData = jsonString.data(using: .utf8)!
let decoder = JSONDecoder()
do {
    let dataModel = try decoder.decode(MyDataModel.self, from: jsonData)
    print(dataModel.key1) // 输出：value1
    print(dataModel.key2) // 输出：123
} catch {
    print("解析JSON失败：\(error)")
}

let jsonString = """
{
    "key1": "value1",
    "key2": 123
}
"""
let jsonData = jsonString.data(using: .utf8)!
do {
    let jsonObject = try JSONSerialization.jsonObject(with: jsonData, options: [])
    if let jsonDict = jsonObject as? [String: Any] {
        for (key, value) in jsonDict {
            print("键名称：\(key)")
            print("对应数据：\(value)")
        }
    }
} catch {
    print("解析JSON失败：\(error)")
}

import SwiftyJSON

let jsonString = """
{
    "key1": "value1",
    "key2": 123
}
"""
let jsonData = jsonString.data(using: .utf8)!
let json = try! JSON(data: jsonData)
for (key, value) in json {
    print("键名称：\(key)")
    print("对应数据：\(value)")
}
