如何修复“并发”仅在iOS 15.0.0或更新的iOS中可用。错误颤动

Question

我最近将Flutter SDK更新为3.0.4，并且在尝试在iOS模拟器上启动时，我的项目将不再构建。

我遇到了以下错误，并在每个错误下实现了解决方案：

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99.

过去有效的解决方案，但现在失败了，因为这也包括在错误消息中： flutter- iOS模拟器部署目标“ iPhoneos_deployment_target”设置为7.0＆amp; amp;构建输入文件找不到googleservice-info.plist

和

error: 'Flutter/Flutter.h' file not found

解决方案，当我上述错误时，过去工作，而不是现在： error：'flutter/flutter.h'文件当flutter上运行时找不到iOS （基本上删除和重建iOS文件夹）

然后，我尝试重新实现此功能（ https://codewithandrea.com/tips/speed-up-cloud-firestore-firestore-xcode-builds/ ）在重建iOS文件夹（需要一个新的podfile）之后，因为构建在上面的解决方案中是永远的，失败，并且在扑面更新之前运行良好。我使用了Firestore版本9.2.0，因为那是我的podfile.lock文件中的内容。

这是我开始获得无法解决的Swift编译器错误的时候，如下所示。其他项目正在运行颤抖的更新和此模拟器。即使将解决方案从上面的“使用Andrea”链接逆转之后，我仍然会遇到同样的错误。

POD安装，POD更新，颤抖的酒吧缓存维修，清洁颤音，扑面酒吧Get，Pod安装 - Repo-Update，这些都无法解决错误。

请帮忙。

错误消息（这不会让我发布整个内容，字符限制）：
