该项目用于Xcode 10+ 不支持使用lbstdc++插件报错异常解决方案
类似这种报错Info: Error: ld: library not found for "-lstdc++.6"

Device(真机)
Put tbd copy to the path
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/
Simulator(模拟器)
Put dylib copy to the path:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/
