【问题描述】：

我在升级到Xcode 13 后才开始遇到这个问题。几天前我将Flutter 升级为2.5.1。

这就是我所看到的：

Could not build the application for the simulator.

我尝试过重新安装 Flutter，删除并重新克隆我的项目，移除 pod，flutter clean + pod install，flutter 缓存修复，以及从项目中移除 Flutter 并重新添加。

每一个都会导致上述错误的一些变化。

我还必须更改我的Podfile --

post_install do |installer|
  installer.pods_project.targets.each do |target|
   target.build_configurations.each do |config|
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
   end
  end
 end

如果我将其还原，则会收到一组不同的错误，其中一些 pod 抱怨设置为 8.0，需要从 9.0 到 14.9.9。

我尝试更改 Runner 项目中的各个 pod，但这不起作用。以上清除了该错误，但现在我面临另一个错误。

请注意，android 运行良好。这只是 iOS。

对这个有什么其他建议吗？

【参考方案1】：

这对我有用：

在 Podfile 中： 替换

post_install do |installer|
  installer.pods_project.targets.each do |target|
   target.build_configurations.each do |config|
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
   end
  end
 end

由

post_install do |installer| 
  installer.pods_project.targets.each do |target| 
    flutter_additional_ios_build_settings(target) 
  end 
end

然后在 Xcode 和 Pods 中打开 iOS 文件，对于每个 Target，在 Build Settings 中，将部署目标设置为 11（也许 9 就足够了）

这是你已经尝试过的吗？

【参考方案2】：

XCode 13 和 Flutter 2.5.3 有类似的问题：通过 xcodebuild 构建随机模块时出现错误（从 UI 构建可以正常工作）。在我尝试删除“有问题的”库之后 - 错误是针对下一个随机库，直到我卡在 Flutter.h 中。

我的问题是，在解决问题的过程中，我在 XCode 中将部署目标更改为 13，但却弄得一团糟：我在 Podfile、Project->Runner->Info中更新了它>，Project->Runner->Build settings，但是忘记为 Targets->Runner->Build Settings 做。

一旦我更新了Targets->Runner->Build Settings，它也开始成功编译。

最终我在所有地方都回滚到了 Target 11.0，它仍然可以编译。
