how fix ?

a solution , workaround avoid issue:

option (solution)- ensure /etc/hosts file contains entry:

127.0.0.1       localhost

option b (workaround)- if must have 127.0.0.1 mapped differently, eg happened doing facebook api testing required set local.mysite.com, disabling xcode debugger:

product -> scheme -> edit scheme -> debugger -> none

will resolve this.
