Flutter 无法导入使用 Cocoapods 安装的依赖项

我已经安装了带有CocoaPods的FBSDK，但由于某些原因无法将其导入到AppDelegate.swft文件中.FBSDK工具包出现在我的Xcode项目中，所以我觉得它应该可以工作. 个

我无论如何都不是iOS开发人员，我只是想为Ffltter SDK编写一个简单的原生插件.有谁有主意吗？

--Here is what the pod file looks like--个

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

if ENV['FLUTTER_FRAMEWORK_DIR'] == nil
  abort('Please set FLUTTER_FRAMEWORK_DIR to the directory containing Flutter.framework')
end

target 'Runner' do
  use_frameworks!

  # Pods for Runner
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
pod 'FBSDKShareKit'

  # Flutter Pods
  pod 'Flutter', :path => ENV['FLUTTER_FRAMEWORK_DIR']

  if File.exists? '../.flutter-plugins'
    flutter_root = File.expand_path('..')
    File.foreach('../.flutter-plugins') { |line|
      plugin = line.split(pattern='=')
      if plugin.length == 2
        name = plugin[0].strip()
        path = plugin[1].strip()
        resolved_path = File.expand_path("#{path}/ios", flutter_root)
        pod name, :path => resolved_path
      else
        puts "Invalid plugin specification: #{line}"
      end
    }
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

---EDIT---个

我收到以下错误ATM:FBSDKCoreKit.framework: No such file or directory.当我在Xcode中打开Frameworks文件夹时，所有文件名都是红色的: 个 But that exact folder in Finder is empty.所以我猜这就是显示错误的原因.问题是如何解决这个问题.

这是我的embedded binaries和linked frameworks and libraries在项目中的样子: 个
