Due to this include,

#include <resolv.h>

We get the following linking error,

ld: warning: text-based stub file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.0.sdk/usr/lib/libresolv.tbd and library file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.0.sdk/usr/lib/libresolv.dylib are out of sync. Falling back to library file for linking.

You are building for the simulator using the Intel 32-bit architecture, which is no longer supported. Check that all of the different architecture settings in your build settings are set to the default values so that you're building for a 64-bit architecture.

Thanks @edford! I set "Build Active Architecture Only" to YES, and the issue was solved.
