Flutter 应用程序无法在 iOS 模拟器上运行

Question

我一直在为 android 和 iOS 开发一个应用程序，该应用程序在 Android 设备上运行良好，但是当我尝试在 iOS 设备上运行时出现一些错误。 我将 xcode 和开发人员工具更新到最新版本，正如在类似问题中所建议的那样，但它们都不适合我。

    Could not build the application for the simulator.

到目前为止我为解决这个问题所做的工作（但失败了）：

• 将 macOS、xcode 和开发者工具更新到最新版本，
• 删除 podfile 并重新创建它，
• 删除iOS文件夹并重新创建它，
• 删除开发者工具并重新安装它，

不幸的是，他们都没有工作。

从零开始，我设法将应用程序安装到模拟器，但崩溃了：

打开 podfile 取消注释平台并将值更改为 11.0。 运行 pod 安装。 在 xcode 中打开 xcworkspave 文件。 转到项目并清理构建文件夹。 如果您看到任何警告图标，则在顶部。 请单击它并解决这些警告。 从 xcode 运行一次，如果它可以工作，那么所有后续构建都应该从你的 ide 工作
