xcode版本16

测试代码：

func performLoginRequest() {
            // 1. 定义请求的 URL
            guard let url = URL(string: "http://-----") else {
                print("Error: Invalid URL for login request.")
                return
            }

            // 2. 定义请求参数
            let parameters: [String: Any] = [
                "user_name": "admin",
                "user_type": 0,
                "tenant_name": "system",
                "login_url": "-----",
                "password": "-----"
            ]

            // 3. 将参数转换为 JSON Data
            guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else {
                print("Error: Could not convert parameters to JSON data.")
                return
            }

            // 4. 创建 URLRequest
            var request = URLRequest(url: url)
            request.httpMethod = "POST"
            request.setValue("application/json", forHTTPHeaderField: "Content-Type") // 设置Content-Type为JSON
            request.httpBody = httpBody

            // 5. 使用 URLSession 发送请求
            let task = URLSession.shared.dataTask(with: request) { data, response, error in
                if let error = error {
                    print("Error during HTTP request: \(error.localizedDescription)")
                    // 尝试打印更详细的错误信息，例如域名解析失败等
                    if let nsError = error as NSError? {
                        print("NS Error Code: \(nsError.code)")
                        print("NS Error Domain: \(nsError.domain)")
                        print("NS Error UserInfo: \(nsError.userInfo)")
                    }
                    return
                }

                guard let httpResponse = response as? HTTPURLResponse else {
                    print("Error: Invalid HTTP response.")
                    return
                }

                print("HTTP Status Code: \(httpResponse.statusCode)")

                if let data = data {
                    // 尝试将响应数据转换为字符串或 JSON
                    if let responseString = String(data: data, encoding: .utf8) {
                        print("HTTP Response String: \(responseString)")
                    }

                    do {
                        if let jsonResponse = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
                            print("HTTP JSON Response: \(jsonResponse)")
                        } else {
                            print("HTTP Response is not a valid JSON dictionary.")
                        }
                    } catch {
                        print("Error parsing JSON response: \(error.localizedDescription)")
                    }
                } else {
                    print("Error: No data received in response.")
                }
            }

            // 6. 启动任务
            task.resume()
        }

说是新版xcode和ios限制不许访问http

网上都说修改Info.plist文件，但新版xcode创建的项目没有Info.plist文件

解决办法：
info→custom ios target properties中添加：

build setting中的info.plist values不用管；

到这里应该就结束了，结果运行还是报错啊

需要彻底清除缓存：

1. Product > Clean Build Folder (Shift + Command + K)。

2. 删除 Derived Data：
   Xcode > Settings… (或 Preferences… for older versions of Xcode)。
   选择 Locations 选项卡。
   点击 “Derived Data” 路径旁边的箭头，在 Finder 中打开该文件夹。
   删除该文件夹内的所有内容（不是删除文件夹本身）。

3. 重新打开 Xcode，并再次运行
