I suddenly get a message on
The resource could not be loaded because the App Transport Security
policy requires the use of a secure connection
A Boolean value used to disable App Transport Security for any domains not listed in the NSExceptionDomains dictionary. Listed
domains use the settings specified for that domain.
Apple announced that iOS apps have until January 1, 2017, to enable App Transport Security.
So,if you plan submit app store after 2017,please turn on ATS.
====== Old answer=====
I submit my app at 9/17/2015, and have passed the app store review process and successfully released the app.
So,I do not think apple will reject the app for this reason for now
My new app passed apple review process at 10/30/2015 with this key set to YES.
