xcode10遇到找不到libstdc++.tdc
打开前往文件夹
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/
这三个目录添加一下这三个库完美解决
库可以去xcode9.4.1或更早版本去找
下面是添加的库百度网盘链接:https://pan.baidu.com/s/1icLltrY_qknW8d44-JQisA
