Question

我按照本教程尝试在我的项目（https://medium.freecodecamp.org/how-to-handle-internet-connection-reachability-in-swift-34482301ea57）中安装并使用了可达性

它说明已全部安装，但我的Import语句仍然出现错误。

下面的图像显示Podfile，pod安装过程，项目目标名称和错误。

有什么主意我想念的吗？我需要检测连接类型（3G，4G，Wifi等）

NetworkStatus.swift标头

import Foundation
import Reachability //No such module 'Reachability'

Podfile

Dans-MacBook-Pro:gnccapp danpalmer$ cat Podfile
# Uncomment the next line to define a global platform for your project
  platform :ios, '12.2'

target 'gnccapp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for gnccapp
  pod 'ReachabilitySwift'
  pod 'Alamofire'

end

Answer 1

确保打开的文件以.xcworkspace而不是.xcodeproj结尾

Answer 2

确保打开由cocoapods（白色）生成的xcworkspace文件
清理构建文件夹（shift + Command + K）
构建项目（命令+ B），即使出现错误也是如此。有时您必须构建项目以使Xcode理解要导入一些cocoapods框架。

希望这会有所帮助
