1. 由于Switf 3.0的引入，导致Socket.IO-Client-Swift编译报错

1）cocopods升级：pod repo update

2）导入8.0.2版本的Socket.IO

2. 编译提示”Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly."

podfile末尾添加如下代码：

post_installdo|installer|

installer.pods_project.targets.eachdo|target|

target.build_configurations.eachdo|config|

config.build_settings['SWIFT_VERSION'] ='3.0'

end

end

end

3. 代码编辑xcode崩溃

插件儿问题，终端输入defaults delete com.apple.dt.Xcode DVTPlugInManagerNonApplePlugIns-Xcode-8.0清除插件即可

4. 工程编译出现一堆nw_socket_handle_socket_event错误

Edit Scheme->Run->Environment Variables添加OS_ACTIVITY_MODE=disable
