Answer 1

我更新 Xcode 时也遇到同样的问题。只需重新登录 Xcode 即可解决。

1. 打开Xcode
2. 打开项目的Runner.xcworkspace文件
3. 登录 Xcode：“签名和功能”->“全部”->“签名”

第 3 项是我的问题。更新 Xcode 时，我被注销了。

    build_configuration.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64 i386'
end

将此代码放入您的 Podfile 中

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |build_configuration|
        build_configuration.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64 i386'
    end
  end
end
