我是第一次在iOS应用上使用flutter项目，该项目已经完成，并且其Android应用已经在Play商店中。问题是我无法在模拟器或物理设备iPhone 6s中运行该应用程序。在过去三天中，我尝试了所有可能的解决方案，但到目前为止都没有奏效。
我在终端中尝试过的命令如答案之一所示：
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flutter upgrade之类的问题，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
Error output from Xcode build:

答案 0 :(得分：1)
尝试从 Android Studio 或带有 flutter run
这个解决方案对我有用：
在 /ios 文件夹中，我在 Xcode 中打开了 .xcworkspace 项目，在那里清理并以我的设备作为目标运行该项目。它在第一次尝试时成功并成功地在我的手机上安装了该应用程序。
在 Xcode 上构建项目并在我的 iPhone 上运行后，我现在可以直接从 Android Studio 再次运行该应用程序，而不会出现错误。
答案 1 :(得分：0)
尝试执行此步骤
清除所有吊舱及其关系：
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
它会自动安装Pod（首次运行可能会花费一些时间，具体取决于您的依赖项。）
