I am trying to test my apps for iOS 12. I have a iPad only app that works fine under Xcode 9. When I try to compile it for the simulator with Xcode 10 GM, the following warning appears:

URGENT: building for iOS Simulator simulator, but linking against dylib (/usr/lib/libstdc++.6.0.9.dylib) built for macOS. Note: This will be an error in the future

It will build, but when running it crashes with the following message:

dyld: lazy symbol binding failed: can't resolve symbol ___cxa_guard_acquire in /Users/.... /.... xxx.app because dependent dylib #1 could not be loaded.

I haven't done anything, it happened on the first try.

Any ideas?

removed '/usr/lib/libstdc++.6.0.9.dylib' from the 'OTHER_LDFLAGS', seems to be fine again.
