我第一次在iOS应用程序上工作，这个项目已经完成，它的android应用程序已经在play store上了。问题是我无法在Emulator或物理设备iPhone 6s中运行该应用程序。在过去的三天里，我尝试了所有可能的解决方案，但到目前为止都没有奏效。
我在终端中尝试的命令，如其中一个答案所示：
flutter pub get
cd ios && pod update
flutter clean && flutter run
尽管我尝试了其他各种命令/步骤来解决这个问题，比如flutter upgrade，但到目前为止没有任何帮助。
我得到的错误：
Running Xcode build...
Xcode build done. 21.4s
Failed to build iOS app

尝试执行以下步骤
清除所有pod及其关系：
在终端：cd ios
flutter clean
rm -Rf Pods
rm -Rf .symlinks
rm -Rf Flutter/Flutter.framework
rm -Rf Flutter/Flutter.podspec
rm Podfile
然后
flutter run
它将自动安装pod(第一次运行时可能需要一些时间，具体取决于您的依赖关系(。
当我试图在iPhone上从Android Studio或带有flutter run的终端运行项目时，也遇到了这个错误
这个解决方案对我有效：
在/ios文件夹上，我在Xcode中打开了.xcworkspace项目，在那里我清理了该项目，然后以我的设备为目标运行该项目。它第一次尝试就成功了，并成功地在我的手机上安装了该应用程序。
该项目在Xcode上构建并在我的iPhone上运行后，我现在可以直接从AndroidStudio再次运行该应用程序，而不会出现错误。
首先，重新安装软件包和pod：
执行这些命令：
cd /ios/
flutter clean
pod deintegrate
rm Podfile.lock
flutter pub get
pod install --repo-update
并再次运行应用程序
其次，升级您的flutter SDK：
运行这些命令：
flutter upgrade
对我来说，升级解决了这个问题。
