react-native-Cocoapods-Swift-Project

https://reactnative.cn/docs/integration-with-existing-apps/

1、创建一个xcode工程，single View就行，项目语言选择swift，oc的直接生成就行不用这么麻烦。
2、把跟目录上创建 node的package.json,执行命令

npm init
npm install react-native --save-dev
npm install react --save-dev
 
3、创建podfile文件，然后执行pod install ，必须第二步完成。代码如下：

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

target 'demo1' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  pod 'DoubleConversion', :podspec => './node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'glog', :podspec => './node_modules/react-native/third-party-podspecs/GLog.podspec'
  pod 'Folly', :podspec => './node_modules/react-native/third-party-podspecs/Folly.podspec'

  pod 'React', :path => './node_modules/react-native', :subspecs =>  [
  'Core',
  'DevSupport',
  'RCTText',
  'RCTNetwork',
  'RCTWebSocket',
  'CxxBridge'
  ]

  # 如果你的RN版本 >= 0.42.0，请加入下面这行
  pod "yoga", :path => "./node_modules/react-native/ReactCommon/yoga"

end

执行npm start 启动服务

运行项目　　

出现如下错误

查了下资料 需要修改

在info.plist中添加 AppTransport Security Settings 在其下再添加 Allow Arbitrary Loads选择为 yes，修改网络可以使用http请求。

运行正常

ok,  新建Swift工程，配合Cocoapods 构建react-native项目就完成了。
