Unity XCode build linker command failed with exit code 1

I used unity 2018.3.5 and xcode 10.1
Who can fix this error for me?

Undefined symbols for architecture armv7:
“_getIPv6”, referenced from:
_IOSIpv6_getIPv6_m9EC241BE5A4FA66C88AC51CBA9EAC10C554BA989 in Bulk_Assembly-CSharp_1.o
(maybe you meant: _IOSIpv6_getIPv6_m9EC241BE5A4FA66C88AC51CBA9EAC10C554BA989)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Set tick on Armv7 in player settings unity
