对于flutter，这是我在<project_root>/ios/Podfile中使用的

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS"] = "armv7"
    config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
  end
end

首先将部署更改为您所选择的:例如'11.0' 并将此步骤添加到pod文件的最后

end
post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
  end
 end
end

对于Flutter使用这个

platform :ios, '10.0'

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

Xcode > Runner >信息部署目标> IOS部署目标:11 ．

开放终端:

pod cache clean --all

.

pod update

对我有用:

rm ios/Podfile
flutter pub upgrade
flutter pub get
cd ios && pod update
flutter clean && flutter run
sudo arch -x86_64 gem install ffi
arch -x86_64 pod install 

无需在pod安装后指定部署目标，您可以为每个pod删除pod部署目标，这将导致部署目标从Podfile继承。

您可能需要运行pod install以使效果发生。

platform :ios, '12.0'

  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
    end
  end
