我正在尝试做一个flutter插件，所以我按照https://flutter.dev/docs/development/packages-and-plugins/developing-packages上提供的步骤创建了一个插件。当我尝试运行一个ios示例时，我得到了一个错误。下面是我运行ios示例应用时得到的日志。
有人能帮我吗？

当我们在终端上通过命令创建插件时，它会创建一个插件，默认为Android的Java和iOS的Objective-C。它可以通过使用命令更改为Android的Kotlin和iOS的Swift，但它只会增加对根文件夹中android/和ios/的支持。这不会改变example/目录中的示例代码。所提供的示例仍然是Java for Android和Objective-C for iOS。所以我从Android Studio创建了一个插件，我通过选中“包括Swift对iOS代码的支持”选项创建了Swift对iOS的支持，它创建了一个使用Swift而不是Objective-C的示例。

如果您使用的是Apple Silicon Chip（M1），则可以执行此操作。

pod cache clean --all
Pod clean
pod deintegrate
sudo gem install cocoapods-deintegrate cocoapods-clean

sudo arch -x86_64 gem install ffi
arch -x86_64 pod repo update
arch -x86_64 pod install

我也面临过这个问题。然后我意识到这是"pod安装"的问题。并在这里找到了解决方案https://github.com/CocoaPods/CocoaPods/issues/10723

sudo arch -x86_64 gem install ffi

并运行：

arch -x86_64 pod install

代替

pod install

每次我把我的项目从一台电脑换到另一台电脑时，我都会遇到这个问题，
我按照这个步骤来解决这个问题，
1.

Delete podfile.lock

2.替换此

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

与

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
    flutter_additional_ios_build_settings(target)
  end
end

3.run

flutter clean
flutter run

您需要设置Swift版本，因为flutter_plugin did not specify a Swift version by default
在ios/Podfile中添加

config.build_settings['SWIFT_VERSION'] = '4.1'  # required by simple_permission

以下列方式：

target 'Runner' do
  use_frameworks!  # required by simple_permission
  ...
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.1'  # required by simple_permission
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

您也可以查看this github thread和这个stackoverflow讨论，以获得关于为什么会发生这种情况的更多细节。

我在项目级别名称SWIFT-VERSION上为Runner添加了一个用户定义的构建设置，其他设置都不起作用。

不用担心。有一个简单的解决方案。创建这个文件-AppResources/iOS/Podfile并将其添加到文件中

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.0'
     end
   end
end

至此，您的项目的SWIFT_VERSION已设置完毕。
