这篇博客演示了如何在Swift UI中结合使用表格、标签、文本框和按钮，并与Objective-C进行混编实现网络请求。在iOS应用开发中，需要在Info.plist文件中配置App Transport Security Settings以允许任意加载，以确保网络请求的正常运行。文中详细介绍了AppDelegate、StudentViewController、MyUIViewController、NewsViewController、DetailViewController以及相关的Oc Model类的实现。

注意:数据请求要在info.plist文件里加上App Transport Security Settings并设置Allow Arbitrary Loads为YES
