问题
I am trying to save information to my contacts through programming and everything goes successful, however when I try to save social profiles I get this SIGABRT ERROR:
2017-01-23 00:10:11.323693 FVSCANNER[765:154249] [MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles

Could someone please explain to me what do I need to do in order to fix this? Thank You in advance!
