Jun 19 Engineering has provided the following information regarding this issue: Thanks for reporting this issue. We have removed support for the old GNU C++ library (stdlibc++) in Xcode 10. Because you’re targeting (iOS6), the compiler selects stdlibc++ by default, which is not longer supported. We will add a new warning in Xcode 10 that clarifies that. To fix your issue you can either upgrade the deployment target to iOS7+ or pass en explicit -stdlib=libc++ argument to your build command (Xcode’s “C++ Standard Library Setting”).
