无法为模拟器构建应用程序。 在 iPhone 11 上启动应用程序时出错。 退出（sigterm）

【问题讨论】：

这很可能是 Flutter 插件问题，可能是因为 Swift 代码过于老旧，与当前的 XCode 不兼容。最好编辑您的 pubspec.yaml 并使用此插件的最新版本：flutter_inappwebview: ^2.1.0+1

@tgram 谢谢先生的回复，但我没有在我的代码中安装这个插件

插件 flutter_inappbrowser 自 2.0.2 版起已重命名为 flutter_inappwebview。请使用新的以获得更好的支持。

是的，先生，这个问题谢谢你，但如果运行应用程序无法连接到我的服务器并得到另一个错误imgur.com/4caHkOH

【参考方案1】：

是的，您需要使用最新版本的依赖项。
