我正在使用 Flutter 和 AWS Auth Cognito，当我尝试在 ios 模拟器上运行 flutter run 时，我收到以下错误消息：
leon@MBP app % flutter run --flavor dev
Launching lib/main.dart on iPhone 15 Pro in debug mode...
Running Xcode build...
└─Compiling, linking and signing... 1,531ms
Xcode build done. 11.0s
Failed to build iOS app
Parse Issue (Xcode): Module 'amplify_auth_cognito' not found
/Users/leon/work/app/ios/Runner/GeneratedPluginRegistrant.m:11:8
Could not build the application for the simulator.
Error launching application on iPhone 15 Pro.
但是，如果我通过以下方式启动它。 XCode 我可以在模拟器上构建应用程序，没有任何问题。在 Android 模拟器上，它也可以通过我的 launch.json 中提供的运行命令或 vs-code 运行选项运行。

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter packages.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# Related to i18n section in dependencies
generate: true
# To add assets to your application, add an assets section, like this:
assets:
- assets/Graphics/
- assets/Graphics/onboarding/
- assets/Graphics/logo/
- assets/Graphics/Cards/
- assets/Graphics/tva/
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:
- family: Inter
fonts:
- asset: assets/google-fonts/Inter/static/Inter-Bold.ttf
weight: 700
- asset: assets/google-fonts/Inter/static/Inter-SemiBold.ttf
weight: 600
- asset: assets/google-fonts/Inter/static/Inter-Regular.ttf
weight: 400
# - family: <Name>
# fonts:
# - asset: <path>.ttf
# style: normal
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
我已经更新了 auth_cogntio 插件，更新了 pod 存储库，解体了 pod，再次安装了 pod 等等。我认为这是一个配置问题，但我不知道还能在哪里查看，因为它通过 XCode 运行运行，但在其他地方都失败了。
我希望它通过 vsCode 运行或终端运行，并通过 ./ios/Runner.xcworkspace UI 构建它
也许其他人也面临同样的问题？
我已经确定了问题的根本原因，这与构建设置有关。具体来说，就是优化级别配置。将优化级别设置为“无”（对于常规构建设置和 Swift 编译器）解决了该问题。
以下是我遵循的步骤：
在构建设置中将优化级别设置为“无”。 在 Swift 编译器设置中设置“无优化”。 进行了颤振清洁。 删除了 Pod 和 Podfile.lock。 重新启动该进程并重新安装 Pod。 此外，我检查了依赖项版本并确保它们更新如下：
amplify_flutter：^2.2.0 至 2.5.0 amplify_auth_cognito：^2.2.0 到 2.5.0 放大核心：^2.2.0 至 2.5.0 最后，我删除并重新添加了 Link Binary with Libraries 中所需的库，这有助于解决链接问题。
