I just downloaded 8.1.10 RC 2

I have both xCode 9.2 and 9.3 entered in preferences. I get a "green" OK in the standalone preferences.

But when I try to build for iOS , I get


Unable to build app for device: linking for arm (arm64) failed with Undefined symbol for
architecture arm 64

"_pthread_key_delete",referenced from:
    |4092 in revsecurity

# and whole series like this
# see screenshot here

What to do?
