iOS 升级Xcode11的libstdc++.6.0.9 的兼容问题

苹果早在 Xcode 8中 就废弃了libstdc++, 给了开发者两年时间过渡, 如今在Xcode 10 & Xcode 11中已不再支持. 在Build Phases > Link Binary With Libraries 中已经搜不到libstdc++的库了

真机路径:

libstdc++.6.0.9.tbd

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.0.sdk/usr/lib

模拟器编译路径:

libstdc++.6.0.9.tbd

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator12.0.sdk/usr/lib

模拟器编运行径:

Xcode 10

libstdc++.6.0.9.dylib

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/

Xcode 11

libstdc++.6.0.9.dylib

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib
