在Xcode9中运行代码有效,但在Xcode10中导致错误.

我正在做自己的测试应用程序，作为 iOS 开发学习过程的一部分（在 Xcode 11.0 上使用 swift 5）。我想在我的登录页面上添加 Facebook 登录，但在导入库时我一直收到No such module 'FacebookCore'消息。

我按照developer.facebook上的说明尝试使用cocoaPods实现SDK，这是我的Podfile

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

target 'TestApp' do

  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for TestApp
  pod 'FBSDKCoreKit'
  pod 'FBSDKLoginKit'

  target 'TestAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'TestAppUITests' do
    # Pods for testing
  end

end

按照 Facebook 的指示执行 …
