Flutter：项目未在 iOS 模拟器上构建

Question

Flutter 应用程序构建在 iOS 模拟器上失败，即使它在 Android 模拟器上成功编译，iOS 和 Android 物理设备也从命令运行第 iOS 行构建成功。

Flutter版本从2.5.3升级到2.8.1后出现此问题。

以前，它工作正常。

Could not build the application for the simulator.

此模拟器也未在 Xcode 中显示。

可能这是一个解决方案：

查看 XCode 上的“构建设置”并将“支持的平台：iphoneos”更改为“支持的平台：iOS”。
