推荐答案

快速解决方案是将所有libstdc ++.*文件从旧的Xcode(9.4)复制到新的Xcode(10.x)

The quick solution is to copy all libstdc++.* file from old Xcode(9.4) to new Xcode(10.x)

对于设备:

cp/Applications/Xcode9.4.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/libstdc++.*/Applications/Xcode10.app/Contents/Developer/Platforms /iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/

cp /Applications/Xcode9.4.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/libstdc++.* /Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/

对于模拟器:

cp/Applications/Xcode9.4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/libstdc++.*/Applications/Xcode10.app/Contents/Developer/Platforms /iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/

cp /Applications/Xcode9.4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/libstdc++.* /Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/
