Had a stray CPATH in my bash_profile that caused ../../scripts/ios-configure-glog.sh to default to /lib/cpp instead of iPhone SDK version of clang.

Found this @torbulent gave me the clues I needed!

[amanikiruga]

If anyone else encounters this issue for a react native project when running expo run:ios, specifically if you are also seeing "xcrun: error: SDK "iphoneos" cannot be located", this stack overflow solved it for me: https://stackoverflow.com/questions/68565356/xcrun-error-sdk-iphoneos-cannot-be-located#_=_
The solution is:

1. Launch Xcode
2. Preferences
3. Locations
4. Make sure there's a dropdown option selected for the command line tools. Or even if it is already selected, reselect it. It will ask for your password.
   Hope this helps!
