Xcode 10 (iOS 12) does not contain libstdc++6.0.9

Question

I download the newest Xcode from Apple, but I found I cannot search the library named \"libstdc++6.0.9\".

Answer 1

I was able to fix the build issue by copying the necessary files from 9.4 to 10.1, both platform libs and runtime. But it only resolves the cases with simulator. My app still stucks at start (splash screen) when running on physical device.
