ios - flutter : iOS build failed

Question

我是使用 Flutter 进行 iOS 开发的新手，最近刚刚在 Flutter 中从 Android 切换到 iOS。

在 mac 上第一次运行该项目时出现以下错误，在 Android 上没有出现任何错误并且运行成功。

Could not build the application for the simulator.

也尝试过，

• pod 安装
• 使用 flutter create 重新创建 iOS 文件夹

但是没有效果

编辑:

将 IPHONEOS_DEPLOYMENT_TARGET 设置为 9.0 后，给出以下输出，

Xcode 13.3 似乎有一些变化，发布于 March 14, 2022.降级到 13.2.1 对我来说是一个可行的解决方法。
